Description:
CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims priority to U.S. Patent Application Ser. No. 61/506,378, filed on 11 Jul. 2011, and titled “Telecommunications Enclosure with Splice Tray Assembly.” 
     
    
     TECHNICAL FIELD 
       [0002]    The present disclosure relates to telecommunications enclosures, and more particularly, to telecommunications enclosures including splice tray assemblies for fiber optic cables. 
       BACKGROUND 
       [0003]    Telecommunications systems typically employ a network of telecommunications cables capable of transmitting large volumes of data and voice signals over relatively long distances. The telecommunications cables can include fiber optic cables, electrical cables, or combinations of electrical and fiber optic cables. A typical telecommunications network also includes a plurality of telecommunications enclosures integrated throughout the network of telecommunications cables. The telecommunications enclosures are adapted to house and protect telecommunications components such as splices, termination panels, power splitters, and wavelength division multiplexers. 
         [0004]    It is often preferred for telecommunications enclosures to be re-enterable. The term “re-enterable” means that the telecommunications enclosures can be reopened to allow access to the telecommunications components housed therein without requiring the removal and destruction of the telecommunications enclosures. For example, certain telecommunications enclosures can include separate access panels that can be opened to access the interiors of the enclosures, and then closed to re-seal the enclosures. Other telecommunications enclosures take the form of elongated sleeves formed by wrap-around covers or half-shells having longitudinal edges that are joined by clamps or other retainers. Still other telecommunications enclosures include two half-pieces that are joined together through clamps, wedges or other structures. Telecommunications enclosures are typically sealed to inhibit the intrusion of moisture or other contaminants. 
       SUMMARY 
       [0005]    Aspects of the disclosure are directed to telecommunications apparatus including an enclosure having an enclosure base and an enclosure cover that join together at a sealed interface that extends about a perimeter of the enclosure. The enclosure has a first end positioned opposite from a second end and has a top side defined by the enclosure cover and a bottom side defined by the enclosure base. The enclosure has side walls that have lengths that extend from the first end to the second end and that have overall side wall heights that extends from the bottom side to the top side of the enclosure. The enclosure cover includes first side wall portions that cooperate with second side wall portions of the enclosure base to define the side walls. The first side wall portions define a majority of the overall side wall heights adjacent the first end of the enclosure and the second side wall portions define a majority of the side wall heights adjacent the second end of the enclosure. 
         [0006]    Aspects of the disclosure also are directed to a seal interface between first and second enclosure pieces of an enclosure. The seal interface extends about a perimeter of the enclosure and includes first and second portions that are offset from one another so as to not be positioned along a common plane. In some implementations, the first portion is positioned along a first plane and the second portion is positioned along a second plane that is parallel to and offset from the first plane. In certain implementations, the seal interface includes a third portion that gradually transitions between the first and second planes. 
         [0007]    Aspects of the disclosure also are directed to a telecommunications apparatus including an enclosure having an enclosure base and an enclosure cover that join together at a sealed interface that extends about a perimeter of the enclosure. The enclosure has a first end positioned opposite from a second end and has a top side defined by the enclosure cover and a bottom side defined by the enclosure base. The enclosure including a plurality of latches for securing the enclosure base and the enclosure cover together and for compressing the sealed interface. The latches are moveable between latched and unlatched positions. The latches include a plurality of latch lever handles that overhand the top side when the latches are in the latched position. In some implementations, the latches include wire clips that are pivotally connected to the latch lever handles and to the enclosure base. In certain implementations, the latch lever handles are trapezoidal in shape. 
         [0008]    Aspects of the disclosure also are directed to a telecommunications apparatus including an enclosure defined at least in part by a first housing piece and a second housing piece. Fiber management trays are pivotally mounted within the enclosure. A resilient member is mounted to the first housing piece. The resilient member presses against the fiber management trays when the first and second housing pieces are secured together so as to resist pivotal movement of the fiber management trays when the enclosure is closed. 
         [0009]    Aspects of the disclosure also are directed to a fiber management tray including a tray body defining a first optical fiber entrance/exit location and a second optical fiber entrance/exit location. The tray body also defines a plurality of fiber storage loop paths and a splice holder location. The tray body further includes a crossing location on a top side of the tray body for crossing a fiber receiving tube routed onto the tray body through the first optical fiber entrance/exit location and an optical fiber routed onto the tray body through the second optical fiber entrance/exit location. The crossing location includes a first surface for supporting the fiber receiving tube and a second surface for supporting the optical fiber, the second surface being recessed relative to the first surface. 
         [0010]    Aspects of the disclosure also are directed to a fiber management device including a base having a front side and a back side; a plurality of fiber management trays pivotally mounted at the front side of the base; and an optical splitter mounted at the back side of the base. The optical splitter has first and second sets of output fibers that are looped about 180 degrees in opposite directions about a bend radius limiter before being passed through though-holes of the base to the fiber management trays at the front side of the base. 
         [0011]    Aspects of the disclosure also are directed to a latch for an enclosure that includes a trapezoidal latch lever handle and a clip pivotally connected to a major side of the latch lever handle. 
         [0012]    Aspects of the disclosure also are directed to a telecommunications apparatus including an enclosure defining a plurality of cable ports bounded by cable port walls, wherein a first portion of each cable port wall is disposed inside the enclosure and a second portion of each cable port wall is disposed outside of the enclosure. 
         [0013]    Aspects of the disclosure also are directed to a fiber optic enclosure defining a cable port having an elongate transverse cross-sectional shape. 
         [0014]    Aspects of the disclosure also are directed to an insert for insertion in a cable port of a fiber optic enclosure. The insert defines a central axis and a single cable receiving opening that has a center that is offset from the central axis. 
         [0015]    Aspects of the disclosure also are directed to an insert adapted for insertion in a cable port. The insert includes a cable through-opening for receiving a telecommunications cable; a post about which a strength member of the cable can be wrapped; and a structure that can be cut by the strength member to form a retention slit. 
         [0016]    Aspects of the disclosure also are directed to an insert adapted for insertion in a cable port. The insert includes a cable through-opening for receiving a telecommunications cable; a post about which a strength member of the cable can be wrapped; and a structure defining a retention slit for receiving the strength member. 
         [0017]    Aspects of the disclosure also are directed to a tube manager including a ring, a cross-section spaced from the ring, and a plurality of arms connecting the ring and the cross-section. The cross-section defines apertures sized to receive loose fiber tubes. The arms extend from the ring to the cross-section without extending beyond either the ring or the cross-section. 
         [0018]    Aspects of the disclosure also are directed to an insert adapted for insertion in a cable port. The insert includes a corrugated conduit for receiving a plurality of fiber tubes; a body; a first manager coupled to the body, and a second manager configured to couple together the body and the corrugated conduit. The first manager defines apertures through which the fiber tubes can be routed out of the insert. The second manager includes a cross-section defining apertures through which the fiber tubes can be routed. The second manager also includes inwardly extending feet having detents that fit within slots defined in the corrugated conduit.

     DETAILED DESCRIPTION 
       [0061]      FIG. 1  is an exploded view of a splice enclosure assembly  100  including a base  101  and a cover  102  that cooperate to form an enclosure  103  that defines an interior  104 . Latch arrangements  105  releasably secure the cover  102  in a closed position relative to the base  101 . The latch arrangements  105  may be released to enable the cover  102  to be removed from the base  101 . A splice tray assembly  106  is mounted within the interior  104  of the enclosure  103 . Various cable port assemblies  107 ,  108 ,  109  are disposed in cable ports defined by the enclosure  103  to enable optical fiber cables to be routed into and out of the enclosure  103 . 
         [0062]    In particular, a first input cable port assembly  107 , a second input cable port assembly  108 , and a plurality of output cable port assemblies  109  are disposed at the enclosure  103 . In the example shown, the enclosure  103  includes one first input cable port assembly  107 , one second input cable port assembly  108 , and five output cable port assemblies  109 . In some implementations, the enclosure  103  may include multiple first cable port assemblies  107  and/or multiple second input cable port assemblies  108 . In still other implementations, the enclosure  103  may include greater or fewer output cable port assembly  109 . 
         [0063]    As used herein, the terms “input” and “output” are used for convenience and are not intended to be exclusory. Optical signals carried over optical fibers may travel in either or both directions. Accordingly, optical fibers routed through either of the input cable port assemblies  107 ,  108  may carry input and/or output signals. Likewise, the optical fibers routed through the output cable port assemblies  109  may carry input and/or output signals. 
         [0064]    The optical fibers routed into the enclosure  103  through the input cable port assemblies  107 ,  108  are optically coupled to the optical fibers routed into the enclosure  103  through the output cable port assemblies  109 . For example, the optical fibers may be coupled together at the splice tray assembly  106  as will be disclosed in more detail herein. In certain implementations, one or more of the optical fibers also may be routed to a splitter (see  FIG. 38 ) as will be disclosed in more detail herein. Fibers output from the splitter may be routed to the splice tray assembly  106 . 
         [0065]    As shown in  FIGS. 2-9 , the enclosure  103  has a top  110 , a bottom  111 , a first side  112 , a second side  113 , a first end  114 , and a second end  115 . The cable port assemblies  107 - 109  are disposed in cable ports at the first end  114  of the enclosure  103 . The second end  115  of the enclosure  103  is generally solid (i.e., does not define cable ports). The base  101  forms the bottom  111  of the enclosure  103  and the cover  102  forms the top  110  of the enclosure  103 . The base  101  forms the majority of the first end  114  of the enclosure  103  and the cover  102  forms the majority of the second end  115  of the enclosure  103 . The base  101  and cover  102  cooperate to forms the sides  112 ,  113  of the enclosure  103 . 
         [0066]    The base  101  includes a bottom surface  142 , a rear wall  143 , and sidewalls  144  extending upwardly from the bottom surface  142  and forwardly of the rear wall  143  to a front wall. The sides  112 ,  113  of the base  101  (i.e., the sidewalls  144 ) are taller towards the first end  114  and shorter towards the second end  115  of the enclosure  103 . The taller sides and first end  114  of the base  101  provide protection for the cable port assemblies  109  when the cover  102  is removed from the base  101 . The shorter sides and second end  115  of the base  101  facilitate access to the splice tray assembly  106  when the cover  102  is removed from the base  101 . In certain implementations, the side walls of the base  101  remain short along a majority of the length of the splice tray assembly  106 . In one implementation, the side walls of the base  101  remain short along the length of the splice tray assembly  106 . 
         [0067]    A gasket or sealing ring  116  ( FIG. 32 ) is disposed between the base  101  and the cover  102  around the perimeter of the enclosure  103 . The gasket  116  inhibits dirt, water, or other contaminants from entering the enclosure  103  when the cover  102  is secured to the base  101  by the latches  105 . In some implementations, the base  101  defines a gasket channel  117  in which the gasket  116  may seat. In certain implementations, the cover  102  forms a tongue  118  that extends downwardly into the cover in alignment with the gasket channel  117 . When the cover  102  is disposed on the base  101 , the tongue  118  compresses the gasket  116  in the channel  117 . In other implementations, the cover  102  may define a second channel instead of the tongue  118  to accommodate the gasket  116 . In still other implementations, the cover  102  may define the channel and the base  101  may define the tongue. 
         [0068]    As shown in  FIG. 9 , the gasket channel  117  extends along the perimeter of the enclosure  103  in a non-planar route. The walls of the base  101  are higher at the first end  114  of the enclosure  103  and lower at the second end  115  of the enclosure  103 . The higher walls at the first end  114  define a first plane along which a first section  120  of the gasket channel  117  extends and the lower walls at the second end  115  define a second plane along which a second section  121  of the gasket channel  117  extends. The base walls transition between the first and second planes to define a transitional section  122  of the gasket channel  117 . In the example shown, the base walls transition on each side  112 ,  113  of the enclosure  103  to define two transitional sections  122 . 
         [0069]    In some implementations, the first section  120  of the gasket channel  117  defines a majority of the gasket channel  117 . For example, the first section  120  of the gasket channel  117  extends along a majority of the lengths of the enclosure  103 . In other implementations, the second section  121  and/or the transitional section  122  may define the majority of the gasket channel  117 . In some implementations, the transitional section  122  has a non-planar contour. For example, in the example shown, the transitional section  122  is contoured in a convex slope (see  FIG. 9 ). In other implementations, the transitional section  122  is planar, but angled relative to the first and second planes. 
         [0070]    In some implementations, the gasket channel  117  defines tabs  119  ( FIGS. 28-32 ) that aid in retaining the gasket  116  within the gasket channel  117 . For example, the tabs  119  may aid in retaining the gasket  118  in the transitional section  122  of the channel  117 . Two opposing tabs  119  extend inwardly from sides of the channel  117  at spaced locations along the channel  117 . In some implementations, the tabs  119  are rounded. In other implementations, the tabs  119  may have any suitable shape (e.g., triangular, rectangular, etc.). In certain implementations, the tabs  119  extend between a bottom of the channel  117  and a top of the channel  117 . In the example shown, the tabs  119  extend at a non-orthogonal angle relative to the bottom surface of the channel  117 . 
         [0071]    As shown in FIGS.  1  and  12 - 14 , the cover  102  is secured to the base  101  using latching arrangements  105 . For example, in certain implementations, each latching arrangement  105  is configured to releasably latch the cover  102  to the base  101 . Each latching arrangement  105  includes a clip member  123  and at least one tensioning member  127 . In the example shown, each clip member  123  includes two tensioning members  127 . One end of the tensioning member  127  couples to the base  101  and the opposite end of the tensioning member  127  attaches to the clip member  123  (e.g., through a passage or recesses in the clip member  123 ). 
         [0072]    In certain implementations, the tensioning member  127  is configured to pivot relative to the base  101  to move the clip member  123  between a lowered position ( FIG. 12B ) and a raised position (see  FIGS. 12C and 13 ). The tensioning member  127  also is configured to pivot relative to the clip member  123  to enable the clip member  123  to latch to the cover  102 . In particular, the clip member  123  is configured to rotate relative to the tensioning member  127  between an unlatched position (see  FIG. 12C ) and a latched position ( FIG. 13 ) as will be discussed in more detail herein. 
         [0073]    In some implementations, at least one latching member  105  is disposed at each side of the enclosure  103 . In certain implementations, the clip members  123  of the latching members  105  cover a majority of the perimeter of the cover  102 . In the example shown, two latching members  105  are disposed at each side  112 ,  113  of the enclosure and one latching member  105  is disposed at each end  114 ,  115  of the enclosure  103  (e.g., see  FIG. 2 ). In other implementations, however, a greater or lesser number of latching members  105  may be disposed at each side  112 ,  113  and/or end  114 ,  115 . In some implementations, the clip member  123  has a generally trapezoidal shape with the abutment section  124  being formed at the longer side and the grip section  125  being formed at the shorter side. Adjacent latching members  105  form miter joints at the corners of the enclosure  103 . 
         [0074]    As shown in  FIG. 14 , the cover  102  is configured to receive the latching members  105 . The cover  102  includes sidewalls  138  extending downwardly from a top surface  130 . The top surface  130  has a central raised surface  131  that is surrounded on all four sides by an inner channel  132 . A raised outer surface  133  bounds the channel  132  on all four sides of the top surface  130 . An outer channel  134  surrounds the raised outer surface  133  and an outer lip  135  bounds the outer channel  134 . Vertical notches  136  are defined at spaced intervals in the outer lip  135 . The vertical notches  136  lead to vertical recesses  139  defined in the sidewalls  138 . The notches  136  and recesses  139  are sized and shaped to accommodate the tensioning members  127 . Two raised structures  137  are disposed on opposite sides  112 ,  113  of the top surface  130 . Each of the raised structures  137  extends from the perimeter of the enclosure  103  to the inner channel  132 . The raised structures  137  are shaped to accommodate the shape of the clip members  123  when the clip members  123  are latched to the cover  102 . In the example shown, the raised structures  137  have angled sides that extend along the angled sides of the adjacent clip members  123  (see  FIG. 13 ). 
         [0075]    The clip members  123  of the latching members  105  are configured to fit with the cover  102 . Each clip member  123  includes an abutment section  124 , a grip section  125 , and notches  126  (see  FIG. 12A ). In some implementations, the grip section  125  is disposed on an opposite side of the clip member  123  from the abutment section  124 . The notches  126  are disposed on the same side of the clip member  123  as the abutment surface  124 . In certain implementations, the abutment section  124  defines a generally S-shaped contour (see  FIG. 12A ). For example, the abutment section  124  defines a concave section  124 A extending downwardly from the top surface of the clip member  123  and a convex surface  124 B extending downwardly from the concave surface  124 A. 
         [0076]    The tensioning member  127  of each latching member  105  includes two legs  128  connected at a first end  129 . In certain implementations, the legs  128  of the spring members  127  are connected at both ends. The first end  129  of the tensioning member  127  is disposed within a downward facing recess  141  in the base  101  (see  FIGS. 12B and 12C ). The recess  141  enables the legs  128  of the tensioning member  127  to be pivoted about the first end  129  between the latching position and the released position. The second end of the tensioning member  127  extends into the clip member  123  to enable the clip member  123  to pivot about the second end. 
         [0077]    To latch the cover  102  to the base  101 , the legs  128  of the tensioning member  127  are pivoted upwardly until the clip member  123  is moved to a position adjacent the cover  102 . The clip member  123  is positioned so the convex section  124 B of the abutment section  124  is disposed in the outer channel  134  of the top surface  130  of the cover  102  and the grip section  125  extends upwardly from the top surface  130  (see  FIG. 12C ). The outer lip  135  fits within the concave section  124 A of the abutment section  124  of the clip member  123 . When the abutment section  124  is disposed in the outer channel  134 , a user pushes the grip section  125  towards the top surface  130  of the cover  102 , thereby causing the clip member  123  to pivot about the convex surface  124 B of the abutment section  124 . 
         [0078]    When the clip member  123  has been pivoted into the latched position ( FIG. 13 ), the grip section  125  is disposed over the inner channel  132 . The clip member  123  tapers inwardly from the abutment section  124  towards the grip section  125 . Accordingly, the grip section  125  is spaced upwardly a distance from the surface of the inner channel  132 . The distance is sufficient to allow a user to grasp the grip section  125  by inserting fingers into the space above the inner channel  132 . Accordingly, a user may unlatch the clip member  123  from the cover  102  by lifting the grip section  105 , thereby causing the clip member  123  to pivot about the convex surface  124 B of the abutment section  124  until the grip section  125  extends upwardly from the cover  102 . 
         [0079]      FIGS. 33-46  illustrate an example implementation of the splice tray assembly  106  in isolation from the enclosure  103 . The splice tray assembly  106  includes a base plate  180  on which one or more groove plates  160  are disposed. Each groove plate  160  is configured to hold one or more splice trays  150 . In certain implementations, the base plate  180  also may be configured to hold one or more splice trays  150 . In the example shown, the base plate  180  is configured to hold two splice trays  150  and four groove plates  160 . Each groove plate  160  in the illustrated embodiment holds nine splice trays  150 . In other implementations, however, the base plate  180  may hold a greater or lesser number of groove plates  160  and each groove plate  160  may hold a greater or lesser number of splice trays  150 . 
         [0080]    As shown in  FIG. 34 , the base plate  180  includes side walls  182  extending upwardly from a bottom surface  181 . One of the side walls  182  defines a plurality of apertures  183  and the other of the side walls  182  defines a plurality of resilient tabs  184 . Each of the tabs  184  has a latch  185  extending inwardly from the tab  184 . Each latch  185  defines a ramp tapering outwardly as the ramp extends towards the bottom surface  181 . Each latch  185  defines a shoulder facing the bottom surface  181 . Each tab  184  is configured to flex outwardly to move the latch  185  away from the apertures  183 . Each tab  184  may be moved independently from the other tabs  184 . 
         [0081]    The base plate  180  includes a first retention arrangement  187  at which one or more first optical fibers may enter the base plate  180  and a second retention arrangement  188  at which one or more second optical fibers may enter the base plate  180 . In certain implementations, the first and second retention arrangements  187 ,  188  are located on opposite sides of the base plate  180 . In certain implementations, the first and second retention arrangements  187 ,  188  are located on a common end of the base plate  180 . The first retention arrangement  187  defines channels through which optical fiber cables or fibers thereof pass. In certain implementations, the channels of the first retention arrangement  187  are ramped downwardly towards the bottom surface  181 . The second retention arrangement  188  includes retaining fingers that form a through-channel. In certain implementations the retaining fingers are spaced apart sufficient to form a gap at the top of the second retention arrangement  188 . 
         [0082]    In some implementations, the base plate  180  is configured to support the splice trays  150 . For example, in certain implementations, the base plate  180  also defines a rest  186  that will be described in more detail herein. In certain implementations, the base plate  180  defines one or more splice tray mounting structures  189  at each of which a splice tray  150  may be pivotally attached. In certain implementations, the splice tray mounting structures  189  are disposed on a platform raised above the bottom surface  181 . In the example shown, the base tray  180  includes two splice tray mounting structures  189  disposed on a raised platform adjacent the rest  186 . 
         [0083]    One or more groove plates  160  ( FIGS. 35-39 ) may be coupled to the base plate  180  (e.g., see  FIGS. 40-42 ). Each groove plate  160  includes a base  161  having side walls  162 . In some implementations, a single groove plate  160  is sized to extend over a majority of the length of the base plate  180 . In other implementations, however, multiple groove plates  160  are disposed along the length of the base plate  180  (see  FIG. 33 ). Each groove plate  160  is sized so that the exterior surfaces of the side walls  162  abut the interior surfaces of the base plate side walls  182  when the groove plate  160  is disposed on the base plate  180 . Latching tabs  163  ( FIG. 33 ) are disposed on one of the side walls  162  and latching shoulders  164  ( FIG. 35 ) are disposed on the other of the side walls  162 . 
         [0084]    To attach the groove plate  160  to the base plate  180 , the latching tabs  163  of the groove plate  160  are inserted into the apertures  183  of the base plate  180 . The side of the groove plate  160  defining the latching shoulders  164  is then pivoted downwardly towards the flexible tabs  184  of the base plate  180 . As the groove plate  160  is pivoted, the latching shoulders  164  ride over the ramp defined by the latches  185  of the flexible tabs  184 , thereby flexing the tabs  184  outwardly. When the groove plate  160  has been pivoted sufficiently for the latching shoulders  164  to clear the latches  185 , the flexible tabs  184  snap back into position so that the shoulders of the latches  185  abut the latching shoulders  164  of the groove plate  160 . To release the groove plate  160  from the base plate  180 , a user flexes the tabs  184  outwardly from the groove plate  160  until the latching shoulders  164  of the groove plate  160  clear the shoulders of the latches  185  of the tabs  184 . 
         [0085]    Each groove plate  160  includes one or more splice tray mounting structures  167  at which splice trays  150  may be pivotally coupled to the groove plate  160 . In certain implementations, the splice tray mounting structures  167  are disposed in a row down the center of the groove plate  160 . Each groove plate  160  also includes structures for guiding the optical fibers from the base plate  180  to the splice trays  150 . For example, in certain implementations, each groove plate  160  includes a tube routing guides  165  and a fiber routing guides  166  for each splice tray mounting structure  167 . In other implementations, each groove plate  160  may include two tube routing guides, two fiber routing guides, or no guides. 
         [0086]    In the example shown in  FIG. 35 , the fiber routing guides  166  are disposed in a row on one side of the splice tray mounting structures  167  and the tube routing guides  165  are disposed in another row an opposite side of the splice tray mounting structures  167 . In certain implementations, each groove plate  160  includes one or more curved flanges extending upwardly from the sides  162  of the groove plate  160 . In some implementations, a shorter curved flange  168  is disposed at the side  162  of the groove plate  160  adjacent the fiber routing guides  166  and a taller curved flange  169  is disposed at the side  162  of the groove adjacent the tube routing guides  165 . 
         [0087]    As shown in  FIG. 41 , when the groove plate  160  is coupled to the base plate  180 , the first retention arrangement  187  of the base plate  180  aligns with a fiber routing channel defined across the groove plates  160  between the shorter curved flanges  168  and the fiber routing guides  166 . The second retention arrangement  188  of the base plate  180  aligns with a tube routing channel defined across the groove plates  160  between the taller curved flanges  169  and the tube routing guides  165 . The curved flanges  168 ,  169  aid in guiding the optical fibers along the routing channels to the splice tray  150 . 
         [0088]    In some implementations, one or more of the fibers received at the first retention arrangement  187  may be routed to an optical splitter  192  at which optical signals carried by the fibers  193  are split onto a plurality of optical fibers  194 .  FIG. 38  shows one example optical splitter  192  disposed at a splitter mounting area  171  in a cavity  170  defined in the bottom of the groove plate  160 . In the example shown, a single splitter  192  is disposed t the splitter mounting area  171 . In other implementations, however, greater or fewer splitters  192  may be disposed in the cavity  170 . In the example shown, the splitter  192  is positioned at one end of the groove plate  160 . 
         [0089]    An input aperture  172  is defined through the top surface  161  of the groove plate  160 . Splitter input fibers  193  are routed from the top surface  161  of the groove plate  160 , through the input aperture  172 , to the splitter  192 . In the example shown, the input aperture  172  is defined at an opposite end of the groove plate  160  from the optical splitter  192 . In certain implementations, the input aperture  172  is disposed at one of the fiber routing guides  166  of the groove plate  160 . In certain implementations, one or more bend radius limiters  176  may be provided between the input aperture  172  and the optical splitter  192  to inhibit excessive bending of the splitter input fiber  193  as the splitter input fiber  193  is routed through the cavity  170 . 
         [0090]    One or more output apertures  173  also are defined through the top surface  161  of the groove plate  160 . The output apertures  173  are disposed at an opposite side of the groove plate  160  from the input aperture  172  and splitter  192 . In the example shown, the output apertures  173  are disposed in a row extending between opposite ends of the groove plate  160 . Each of the apertures  173  is elongated in the direction extending between the sides  162  of the groove plate  160 . In certain implementations, the top surface  161  defines ramps  174  leading to the output apertures  173 . In the example shown, nine output apertures  173  extend through the top surface  161 . In other implementations, however, the top surface  161  can define greater or fewer output apertures  173 . In certain implementations, the output apertures  173  are disposed at two or more of the tube routing guides  167  of the groove plate  160 . 
         [0091]    Two or more splitter output fibers  194  extend from the splitter  192  towards the output apertures  173 . One or more bend radius limiters  176  are provided to aid in routing the splitter output fibers  194  around the cavity  170  to the output apertures  173 . In some implementations, the bend radius limiters  176  are positioned to provide a first routing path  177  that extends from the splitter  192 , along a first end of the groove plate  160 , past the row of output apertures  173 , around a bend radius limiter  176  towards a second end of the groove plate  160 , and towards the output apertures  173 . In some implementations, the bend radius limiters  176  are positioned to provide a second routing path  178  that extends from the splitter  192 , towards the second end of the groove plate  160 , along the second end past the row of output apertures  173 , around a bend radius limiter  176  towards the first end of the groove plate  160 , and towards the output apertures  173 . 
         [0092]    In the example shown, the splitter output fibers  194  routed to the output apertures  173  located at the second end of the groove plate  160  follow the first routing path  177  and the splitter output fibers  194  routed to the output apertures  173  located at the first end of the groove plate  160  follow the second routing path  176  (e.g., see  FIG. 38 ). As shown in  FIGS. 38 and 39 , in certain implementations, a retaining arrangement  175  is disposed at each output aperture  173 . Each retaining arrangement  175  defines a slit aligned with the output aperture  173  that guides the respective splitter output fiber  194  through the aperture  173  and onto the top surface  161  of the groove plate  160  (see  FIG. 39 ). 
         [0093]    Each groove plate  160  includes one or more splice tray mounting arrangement  167  at which the splice trays  150  are mounted. In certain implementations, each splice tray mounting arrangement  167  include a hinge mount through which a hinge-pin of a corresponding splice tray  150  is inserted to pivotally couple to the groove plate  160 . The base plate  180  also may include one or more such splice tray mounting arrangement  189 . Optical fibers received at the base plate  180  are routed over the groove plates  160  to the splice trays  150 . 
         [0094]      FIG. 45  shows an example splice tray  150  suitable for use with the groove plate  160  and/or base plate  180  described above. The front of each splice tray  150  includes a splice area  151  at which two or more optical fibers may be optically coupled together. Each splice tray  150  also includes a first entrance  152  through which at least a first optical fiber enters the splice tray  150  and a second entrance  154  through which at least a second optical fiber enters the splice tray  150 . In certain implementations, the entrances  152 ,  154  are located adjacent the hinge pin of the splice tray  150 , but face in different directions. For example, the first entrance  152  of each splice tray  150  may be aligned with a corresponding one of the fiber routing guides  166  and the second entrance  154  may be aligned with a corresponding one of the tube routing guides  165 . 
         [0095]    The first entrance  152  guides the fibers onto the splice tray  150  along a first direction and the second entrance  154  guides the fibers onto the splice tray  150  along a second direction. The optical fibers entering the splice tray  150  at the second entrance  154  cross the optical fibers entering the splice tray  150  from the first entrance  152 . To facilitate the interactions of these fibers, a recessed channel  153  is provided at the first entrance  152 . Accordingly, any fibers routed through the second entrance  154  cross over any fibers routed through the first entrance  152  and the recessed channel  153 . 
         [0096]    The front of each splice tray  150  also includes a first routing channel  157  for the fibers extending through the first entrance  152  and a second routing channel  156  for the fibers extending through the second entrance  154 . The routing channels  156 ,  157  guide the fibers from the entrances  152 ,  154  to the splice area  151 . In certain implementations, the first routing channel  157  extends from the first entrance  152 , along a recessed channel  153 , and into the first routing channel  157  that guides fibers around one or more spool  158  disposed at a central portion of the splice tray  150 . In the example shown, the first routing channel  157  wraps around two fiber spools separated through the middle by a slit to enable the fibers to be wound in a “FIG.  8 ” configuration. 
         [0097]    The second routing channel  156  extends from the second entrance  154 , across a top of the recessed channel  153 , and into a helical outer channel located at an outer edge of the splice tray  150 . The helical channel  156  guides the fibers around the splice tray  150  and opens into the first routing channel  156  in an opposite direction from the first entrance  152 . In some implementations, the optical fibers routed onto the splice tray from the second entrance  154  are disposed in a loose tube  195  (see  FIG. 46 ). One or more retaining fingers  155  are provided at the second entrance  154  and along the helical routing channel  156  to aid in retaining the tube  195 . 
         [0098]    In the example shown in  FIG. 40 , the splice trays  150  are disposed in a row with a first splice tray  150 A at a first end and another splice tray  150 N at a second end. Each splice tray  150  is pivotally mounted to the respective groove plate  160  or base  180  so that each splice tray  150  may be separately pivoted between a rest position and an unblocking position. When in the rest position, each of the splice trays  150  is oriented so that the front of the tray  150  generally faces towards the first splice tray  150 A. In certain implementations, the front of the splice tray  150  also faces at least partially upwardly away from the respective groove plate  160  or base plate  180 . When in the unblocking position, each of the splice trays  150  is oriented so that the front of the tray  150  faces generally downwardly towards the respective groove plate  160  or base plate  180 . 
         [0099]    In the example shown in  FIGS. 40-43 , all of the splice trays  150  are disposed in the rest position. Each splice tray  150  rests on the splice tray  150  behind it. The rear of the splice tray  150 N at the second end of the row abuts the rest  186  of the base plate  180 . The rest  186  maintains the splice trays  150  in the rest position. The first splice tray  150 A is accessible to a user. No splice tray  150  blocks access to the first splice tray  150 A and the front of the first splice tray  150 A faces partially upwardly. In some implementations, the splice trays define a rounded edge  159 . For example, as shown in  FIG. 44 , the perimeter along the rear side of each splice tray  150  may have a rounded contour  159 . The rounded contour may enhance the movement of the splice trays  150  between the rest and unblocking positions. 
         [0100]    To access a select splice tray  150  from further along in the row, all of the splice trays  150  located in front of the selected splice tray  150  are moved to the unblocking position and the selected splice tray  150  remains in the rest position. Accordingly, no splice trays  150  will block access to the selected splice tray  150  and the front of the selected splice tray  150  faces partially upwardly. 
         [0101]    The splice tray assembly  106  is configured to be disposed within the base  101  so that the row of splice trays  150  extends between the first end  114  and the second end  115  of the enclosure  103  (see  FIG. 1 ). In the example shown, the splice trays  150  are oriented so that the front of each splice tray  150  faces generally towards the second end  115  of the enclosure when in the rest position. In certain implementations, the front of each splice tray  150  also faces partially towards the cover  102  when in the rest position. In other implementations, however, the splice trays  150  may be oriented to face generally in a different direction relative to the enclosure  103 . 
         [0102]    As shown in  FIGS. 10 and 11 , a cushioning strip  190  may be disposed beneath the cover  102  to aid in retaining the splice trays  150  in the rest position while the cover  102  is attached to the base  101 . The cushioning strip  190  extends along the length of the platform  130  of the cover  102  between the first end  114  and the second end  115 . The cushioning strip  190  is sufficiently thick to contact the tops of the splice trays  150  when the splice trays  150  are disposed in rest positions and the cover  102  is attached to the base  101 . In certain implementations, the cushioning strip  190  is formed from foam or resin. In other implementations, however, the cushioning strip  190  may be formed from any resilient material or material otherwise capable of retaining the splice trays  150  in position. 
         [0103]    Referring to  FIGS. 47-61 , optical fibers are routed to the splice assembly  106  in the enclosure  103  via cable ports  145 - 147 . Ducts  200  extend through the first end  114  of the base  101  to define the cable ports  145 - 147 . For example, a first duct  201  extends through the first end  114  at the first side  112  to define the round input port  145 ; a second duct  202  extends through the first end  114  at the first side  112  to define the oblong input port  146 ; and multiple ducts  203  extend through the first end  114  at the second side  113  to define the output ports  147 . In the example shown, five ducts  203  extend through the first end  114  to define the five output ports  147 . One of the output ducts  203  is located at the first side  112  of the base  101  above the second duct  202 . 
         [0104]    As shown in  FIG. 47 , each of the ducts  200  has a first end extending partially into the interior  104  of the enclosure  103  and a second end extending partially out of the enclosure  103 . By disposing a portion of each duct  200  within the enclosure interior  104 , an overall length of the enclosure  103  is reduced as compared to an enclosure having ducts  200  extending only outside of the enclosure  103 . In some implementations, about half of each duct  200  is disposed within the interior  104  and about half is disposed outside of the enclosure  103 . In other implementations, a majority of each duct  200  may be disposed within the interior  104  or outside of the enclosure  103 . 
         [0105]    In some implementations, a tear-off sealing member  209  is disposed in one or more of the ducts  200 . Each sealing member  209  extends across the duct  200  to inhibit contaminants from entering the enclosure  103 . The sealing members  209  are connected to the ducts with weak webs or other frangible connections that facilitate removing the sealing members  209  from the ducts  200 . Accordingly, the sealing members  209  temporally seal the ducts  200  until the cable port is needed. In certain implementations, the sealing members  209  are configured to tear away cleanly (e.g., using pliers). Additional information pertaining to example implementations of the sealing members  209  is provided in Exhibit A, which is attached to the end of this disclosure. The disclosure of Exhibit A is hereby incorporated herein by reference in its entirety. 
         [0106]    In some implementations, the first duct  201  and the output ducts  203  are round. However, the first duct  201  is smaller than the output ducts  203 . In some implementations, the first duct  201  is sized to receive one input cable having one or more optical fibers and the output ducts  203  are sized to receive multiple tubes of optical fibers from one or more optical cables. In certain implementations, the second duct  202  is generally oblong. In some implementations, the second duct  202  is sized to receive two input cables, each having one or more optical fibers. The second duct  202  has a height H that is less than a width W (see  FIG. 48 ). In certain implementations, the height H is less than half of the width W. In other implementations, however, each of the ducts  200  may be sized to receive greater or fewer fiber optic cables. 
         [0107]      FIGS. 49-53  show a first example port assembly  107  that is suitable for sealing one or more fiber optic cables entering the enclosure through the round input port  145 . The first example port assembly  107  includes a body  210  extending between a first end  211  and a second end  212 . The port body  210  defines a through passage  213  extending between the first and second ends  211 ,  212 . As shown in  FIGS. 2 and 3 , the port body  210  is disposed within the cable port  145  defined by the first duct  201  at the first end  114  of the base  101 . The first end  211  of the port body  210  extends outwardly from the duct  201  and the second end  212  of the port body  210  extends into the interior  104  of the enclosure  103  from the duct  201 . Cables passing through the first example port assembly  107  are routed through a guide member  225  ( FIGS. 1 and 11 ) to the first retention arrangement  187  of the base plate  180  of the splice tray assembly  106 . 
         [0108]    An aperture  218  is defined at the first end  211  of the port body  210 . Fiber optic cables entering the enclosure  103  are routed through the aperture  218  at the first end  211  of the port body  210 , through the passage  213 , and out through the second end  212  of the port body  210 . As shown in  FIG. 51 , the aperture  218  is not aligned with a central longitudinal axis A of the port body  210 . Rather, the aperture  218  is offset from the central longitudinal axis A. A strength member retaining arrangement  214  is disposed at the second end  212  of the port body  210 . The retaining arrangement  214  is offset from the central longitudinal axis A of the port body  210  in a different direction than the aperture  218 . 
         [0109]    A cable routed through the port body passage  213  extends at an angle from the aperture  218  to the retaining arrangement  214 . For example,  FIG. 52  shows a fiber optic cable  220  routed through the cable port body  210 . The fiber optic cable  220  includes a jacket  221  surrounding one or more optical fibers and a strength member  223 . In the example shown, the optical fibers of the fiber optic cable  220  are retained in loose tubes  222 . In other implementations, however, the optical fibers may be retained in ribbons or may have not buffer tubes. In certain implementations, the fiber optic cable  220  also includes additional strength members (e.g., aramide yarn)  224 . 
         [0110]    The strength member retaining arrangement  214  provides structure to which the strength members  223 ,  224  of the fiber optic cables  220  may be anchored to secure the cable  220  to the first port assembly  107 . The retaining arrangement  214  includes a flange  215  that defines a recess  219  in which a central strength member  223  of the cable  220  may be disposed. The strength member  223  may be held in the recess  219  with epoxy or other adhesive. Angling the cable  220  via the offset aperture  218  at the first end  211  of the port body  210  guides the cable towards a side of the second end  212 , thereby facilitating gluing the strength member  223  within the recess  219 . 
         [0111]    The strength member retaining arrangement  214  also includes two teeth  216  that extend outwardly from the flange  215  generally parallel to the longitudinal axis of the port body  210 . The teeth  216  are angled to form a narrow channel therebetween. A wall  217  extends across at least part of the channel. For example, in some implementations, the wall  217  extends from the flange  215  to an end of the teeth  216 . In other implementations, however, the wall  217  extends over only part of the height of the teeth (see  FIG. 50 ). To secure a cable  220  to the port body  210 , the additional strength members  224  of the cable  220  may be wrapped (e.g., one, two, or three times) around the flange  215  and slid between the teeth  216  towards the flange  215  (see  FIG. 53 ). 
         [0112]    The wall  217  between the teeth  216  is sufficiently frangible to enable the strength members  224  to cut a slit through the wall  217  so that the strength members  224  are captured in the slit. For example, in one implementation, the wall  217  is significantly thinner than the teeth  216 . In some implementations, the wall  217  has a thickness ranging from about 0.25 mm to about 0.7 mm. In certain implementations, the wall  217  has a thickness ranging from about 0.35 mm to about 0.5 mm. In certain implementations, the wall  217  has a thickness of about 0.3 mm. In certain implementations, the wall  217  has a thickness of about 0.4 mm. In certain implementations, the wall  217  has a thickness of about 0.5 mm. In certain implementations, the wall  217  has a thickness of about 0.6 mm. 
         [0113]      FIGS. 54-57  show a second example port assembly  108  that is suitable for sealing one or more fiber optic cables entering the enclosure through the oblong input port  146 . The second example port assembly  108  includes a body  230  extending between a first end  231  and a second end  232 . The second port body  230  has a generally oblong shape that is sized and shaped to fit within the second input port  146 . A height H′ of the second port body  230  is less than a width W′ of the second port body  230 . In certain implementations, the height H′ of the second port body  230  is less than half of the width W′ as shown in  FIG. 56 . In the example shown, two apertures  238   a ,  238   b  are disposed at the first end  231  of the second port body  230 . Each aperture  238   a ,  238   b  leads to a passage  233   a ,  233   b , respectively, that passes through the second port body  230  to the second end  232 . 
         [0114]    As shown in  FIGS. 2 and 3 , the second port body  230  is disposed within the cable port  146  defined by the second duct  202  at the first end  114  of the base  101 . The first end  231  of the second port body  230  extends outwardly from the duct  202  and the second end  232  of the second port body  230  extends into the interior  104  of the enclosure  103  from the duct  202 . Cables passing through the second example port assembly  108  are routed through a guide member  225  ( FIGS. 1 and 11 ) to the first retention arrangement  187  of the base plate  180  of the splice tray assembly  106 . 
         [0115]    At least one strength member retaining arrangement  234  is disposed at the second end  232  of the second port body  230 . In the example shown, first and second retaining arrangements  234   a ,  234   b  are disposed at the second end  232 . The first retaining arrangement  234   a  is positioned to be accessible to cables routed through the first passage  233   a  from the first aperture  218   a  and the second retaining arrangement  234   b  is positioned to be accessible to cables routed through the second passage  233   b  from the second aperture  218   b . In the example shown, the retaining arrangements  234   a ,  234   b  are positioned at adjacent sides of the passages  233   a ,  233   b.    
         [0116]    Each of the strength member retaining arrangements  234   a ,  234   b  provides structure to which the strength members of fiber optic cables may be anchored to secure the cables to the second port assembly  108 . The retaining arrangement  234   a ,  234   b  each includes a flange  235  that defines a recess  239  ( FIG. 57 ) in which a central strength member of a fiber optic cable may be disposed. The strength member may be held in the recess  239  with epoxy or other adhesive. 
         [0117]    Each strength member retaining arrangement  234   a ,  234   b  also includes two teeth  236  that extend outwardly from the flange  235  generally parallel to the longitudinal axis of the second port body  230 . The teeth  236  are angled to form a narrow channel therebetween. A wall  237  extends across at least part of the channel. For example, in some implementations, the wall  237  extends from the flange  235  to an end of the teeth  236 . In other implementations, however, the wall  237  extends over only part of the height of the teeth  236  (see  FIG. 57 ). 
         [0118]    To secure a cable to the second port body  230 , the additional strength members of the cable may be wrapped (e.g., one, two, or three times) around the flange  235  of the corresponding retaining arrangement  234   a ,  234   b  and slid between the teeth  236  towards the respective flange  235 . The wall  237  between the teeth  236  is sufficiently frangible to enable the strength members to cut a slit through the wall  237  so that the strength members are captured in the slit. For example, in one implementation, the wall  237  is significantly thinner than the teeth  236 . 
         [0119]    In some implementations, the wall  237  has a thickness ranging from about 0.25 mm to about 0.7 mm. In certain implementations, the wall  237  has a thickness ranging from about 0.35 mm to about 0.5 mm. In certain implementations, the wall  237  has a thickness of about 0.3 mm. In certain implementations, the wall  237  has a thickness of about 0.4 mm. In certain implementations, the wall  237  has a thickness of about 0.5 mm. In certain implementations, the wall  237  has a thickness of about 0.6 mm. 
         [0120]      FIGS. 58-61  show one example implementation  240  of a third port assembly  109  that is suitable for sealing one or more fiber optic cables entering the enclosure  103  through one of the output ports  147 . As shown in  FIGS. 2 and 3 , the example third port assembly  240  is disposed within the cable port  147  defined by the third duct  203  at the first end  114  of the base  101 . One end of the third port assembly  240  extends outwardly from the duct  203  and the opposite end of the third port assembly  240  extends into the interior  104  of the enclosure  103  from the duct  203 . Cables passing through the third example port assembly  240  are routed to the second retention arrangement  288  of the base plate  180  of the splice tray assembly  106 . 
         [0121]    The third port assembly  240  includes a body  241  having a first end and a second end. The first end of the body  241  is configured to extend over a first end of a corrugated conduit  242 . In certain implementations, the corrugated conduit  242  is flexible and/or may limit the maximum bend radius of the optical fibers passing through the third port assembly  109 . A first manager  243  is disposed at the second end of the body  241 . The first manager  243  defines a plurality of apertures through which tubes of optical fibers are routed to organize the tubes exiting the third port assembly  240 . A second manager  244  is disposed at the first end of the corrugated conduit  242  towards the first end of the body  241 . 
         [0122]    The third port assembly  240  receives tubes (e.g., loose fiber tubes and/or blown fiber tubes) for receipt of fibers during a fiber installation process. The body  241  of the third port assembly  240  defines a chamber for receiving resin between the first and second managers  243 ,  244 . In certain implementations, the first tube manager  243  defines a center passage ( FIG. 59 ) for receipt of the poured resin. The resin seals around the tubes when it hardens to hold the tubes in place within the body  241 . The hardened resin also inhibits disassembly of the third port assembly  240 . 
         [0123]    As shown in  FIGS. 60 and 61 , the second manager  244  is configured to organize the tubes extending through the conduit  242  to the body  241 . The second manager  244  includes a cross-piece  246  spaced from a ring  245 . Arms  247  extend between the ring  245  and the cross-piece  246 . In the example shown, two arms  247  are disposed on opposite sides of the circumference of the ring  245 . In certain implementations, the arms  247  extend from the ring  245 , past the cross-piece  246 , and loop back to the cross-piece  246 . 
         [0124]    The ring  245  fits around the second end of the body  241  and around the conduit  242  to secure the body  241  to the conduit  242 . The cross-piece  246  defines apertures  248  through which the loose tubes may be routed to guide the tubes through the third port assembly  240 . In the example shown, the apertures  248  are clover shaped so that three loose tubes fit within each aperture  248 . A guide arrangement  249  extends from the cross-piece  246  towards the ring  245 . A center post extends from the cross-piece  246  away from the ring  245 . 
         [0125]    To assemble the third port assembly  240 , fiber tubes are routed through the conduit  242 . The second manager  244  is disposed so that the cross-piece  246  is laid across one end of the conduit  242  with the guide arrangement  249  extending into the conduit  242 . For example, the end of the conduit  242  may seat in the looped-back portion of the arms  247  of the second manager  244 . The tubes are routed through the apertures  248  in the cross-piece  246 . The ring  245  is disposed around the conduit  242 . The body  241  is slid over the tubes until one end of the body  241  slides between the ring  245  and the conduit  242 . The body  241  is rotated relative to the ring  245  to lock the example third port assembly  240  together. 
         [0126]      FIGS. 62-3  show an alternative implementation  250  of an example third port assembly  109  that is suitable for use with the enclosures  103  described herein. The example third port assembly  250  also includes a body  251  having a first end that is configured to extend over a first end of a corrugated conduit  252 . In certain implementations, the corrugated conduit  252  is flexible and/or may limit the maximum bend radius of the optical fibers passing through the third port assembly  250 . A first manager  253  is disposed at a second end of the body  251 . The first manager  253  defines a plurality of apertures through which tubes of optical fibers are routed to organize the tubes exiting the third port assembly  250 . A second manager  254  is disposed at the first end of the corrugated conduit  252  towards the first end of the body  251 . 
         [0127]    As shown in  FIG. 63 , the second manager  254  is configured to organize the tubes extending through the conduit  252  to the body  251 . The second manager  254  includes a cross-piece  256  spaced from a ring  255 . Arms  257  extend between the ring  255  and the cross-piece  256 . In the example shown, two arms  257  are disposed on opposite sides of the circumference of the ring  255 . In certain implementations, the arms  257  extend from the ring  255  to the cross-piece  256  without extending past the cross-piece  256 . 
         [0128]    The ring  255  is sized to fit around the second end of the body  251  and around the conduit  252  to secure the body  251  to the conduit  252 . Feet  260  protrude inwardly from the ring  255  to provide detents ( FIG. 63 ) that are sized to fit within the slots  252 ′ ( FIG. 62 ) of the corrugated conduit  252 . The cross-piece  256  defines apertures  258  through which the loose tubes may be routed to guide the tubes through the third port assembly  250 . In one example implementation, the apertures  258  are clover shaped so that three loose tubes fit within each aperture  258 . A guide arrangement  259  extends from the cross-piece  256  towards the ring  255 . A center post extends from the cross-piece  256  away from the ring  255 . 
         [0129]    To assemble the third port assembly  250 , fiber tubes are routed through the conduit  252 . The second manager  254  is disposed so that the cross-piece  256  is laid across one end of the conduit  252  with the guide arrangement  259  extending into the conduit  252 . The feet  260  prevent or reduce resin leakage during assembly before curing. In certain implementations, the feet  260  of the second manager  254  lock with the slots  252 ′ defined in the exterior surface of the corrugated conduit  252  to restrain the second manager  254  from moving relative to the conduit  252  in an axial direction during assembly. The tubes are routed through the apertures  258  in the cross-piece  256  of the second manager  254 . The body  251  of the third port assembly  250  is slid over the tubes until one end of the body  251  slides between the ring  255  and the conduit  252 . The body  251  is rotated relative to the ring  255  to lock the example third port assembly  250  together. 
         [0130]    Additional information pertaining to example implementations of the third example port assembly  109  is provided in Exhibit B, which is attached to the end of this disclosure. The disclosure of Exhibit B is hereby incorporated herein by reference in its entirety.
