No. 15/476,690, filed Mar. 31, 2017, now U.S. Pat.

     BACKGROUND 
     Embodiments of this disclosure relate to assemblies, systems, and methods for deploying fiber optic cable to a fiber optic device. 
     Due to the high demand for telecommunication services, fiber optic networks are becoming more popular worldwide. To build fiber optic networks, a service provider installs multiple fiber optic cables, which can require multiple fiber distribution terminals that optically couple the fibers of fiber optic cables. Fiber distribution terminals can provide multiple access points to a fiber optic network, which is useful when providing network access to a plurality of separate units in multiple-unit buildings such as apartments, condominiums, businesses, and the like. 
     A plurality of end-user separate units can include an end-user fiber optic device such as optical node terminals, Ethernet routers, desktop computers, laptops and/or presentation screens and the like. Each end-user fiber optic device can be located at different locations within each separate subscriber unit. Thus, the length and orientation of each fiber optic cable running to the end-user fiber optic device varies from one subscriber end-user device to another subscriber end-user device. So for each installation, the installer must cut the fiber optic cable to a specific length and then fix a connection between the subscriber end-user device and a network terminal. Moreover, each subscriber end-user device has specific adapter ports that require a specific connector installed at the fiber optic cable. So each time the installer must configure specific connectors that are adapted to optically couple with the specific adapter ports of the subscriber end-user device. 
     Typically, the network installer performs these tasks at the installation site as required by the particular network terminal and subscriber devices. This increases the burden of the installer to carry the necessary adapters, connectors, optical fiber cables, and fiber distribution terminals as well as various installation tools. This is also time consuming and requires specific skills such as splicing of the optical fiber cables, and configuring the specific connectors to each optical fiber. 
     Accordingly, there is a need for fiber optic cable deployment assemblies and systems that can be easily installed to connect a subscriber end-user device to a network. 
     SUMMARY 
     In some embodiments, an assembly for deploying fiber optic cable includes a housing, a spool, and a component module. The housing defines a cavity and includes a wall. The wall defines an opening that allows a first portion of a fiber optic cable to pass there through. The spool stores a second portion of the fiber optic cable and is rotatably coupled to the housing within the cavity of the housing. The component module is releasably coupled to the housing. The component module includes an adapter configured to optically couple the fiber optic cable to another fiber optic cable. 
     The fiber optic cable stored on the spool can include a pre-terminated fiber connector configured to be optically coupled to the adapter. The pre-terminated fiber connector can be configured to be releasably coupled to the adapter. 
     The spool can include a connector holder configured to releasably couple the pre-terminated fiber connector to the spool. The connector holder can be configured to be releasably coupled to a panel of the spool. 
     The assembly can include a fan out that separates fibers of the fiber optic cable. The fan out can be coupled to the spool. The spool can also include a retaining structure configured to releasably couple the fan out to the spool. 
     The spool can be positioned between the component module and the housing such that the component module secures the spool within the cavity defined by the housing. The spool can rotate while the component module remains stationary. 
     The component module can be releasably coupled to the housing at a plurality of orientations relative to the housing. 
     The assembly is configured to be mounted to a mounting surface. In some embodiments, the assembly can be configured to be mounted to a mounting bracket that (a) positions the opening defined by the wall of the housing within a cavity defined by the mounting surface and (b) positions the adapter on a side of the mounting surface opposite of the cavity defined by the mounting surface. In some embodiments, the assembly is configured to be mounted to a mounting bracket that positions the opening defined by the wall of the housing and the adapter on the same side of the mounting surface. 
     The component module can also include an electronic component. The electronic component can be an access point to a wireless network or an internet of things gateway. 
     The assembly can also include a second component module releasably coupled to the component module comprising the adapter. The second component module can include an electronic component or another adapter. 
     The component module comprising the adapter can also include at least two locations configured to secure the adapter. 
     In some embodiments, a fiber distribution system includes a fiber distribution terminal. The fiber distribution terminal includes a first fiber optic cable, a rotatable spool storing a portion of the first fiber optic cable, and a first adapter optically coupled to the first fiber optic cable. The system further includes an assembly, separate from the fiber distribution terminal, that includes a second rotatable spool storing a second fiber optic cable optically coupled to the first adapter. The assembly also includes a second adapter optically coupled to the second fiber optic cable, and includes a third fiber optic cable optically coupled to the second adapter. And the system includes an end-user fiber optic device optically coupled to the third fiber optic cable. 
     The assembly can be positioned at a subscriber location. The subscriber location can be a separate unit of a multi-unit building. The fiber distribution terminal can be located outside of the subscriber location. 
     The system can also include a second assembly, separate from the fiber distribution terminal. The second assembly can include a third rotatable spool storing a fourth fiber optic cable. The second assembly can also include a third adapter optically coupled to the fourth fiber optic cable. The system can also include a fifth fiber optic cable optically coupled to the third adapter, and a second end-user fiber optic device optically coupled to the fifth fiber optic cable. The fiber distribution terminal can include a fourth adapter that optically couples the first fiber optic cable to the fourth fiber optic cable. 
     The first assembly can also include a housing that defines a cavity and includes a wall. The wall can define an opening through which the third fiber optic cable passes. The second spool can be rotatably mounted to the housing within the cavity of the housing. The first assembly can also include a component module releasably coupled to the housing. The component module is configured to releasably couple with the second adapter.

       FIGS. 1 and 2  illustrate an embodiment of an assembly  100  for deploying fiber optic cable. Assembly  100  can include a housing  102 , a spool  108  (shown in  FIG. 2 ), a component module  104 , and a cover  106 . Assembly  100  can be used to optically couple a subscriber end-user fiber optic device to a network, for example, to a separate fiber distribution terminal of the network. Housing  102  can be configured to store spool  108 , which stores at least a portion of a fiber optic cable. Component module  104  can be configured to secure spool  108  within housing  102  and can include at least one of (a) an adapter for optically coupling the fiber optic cable stored on spool  108  with another fiber optic cable, and (b) an electronic component. And cover  106  can be configured to close a cavity defined by component module  104 . Assembly  100  can be configured to be mounted to a mounting surface, e.g., a wall, pole, or shelf, either directly or indirectly using a mounting bracket. Embodiments of housing  102 , spool  108 , component module  104 , and cover  106  are described in more detail below. 
     Exemplary Housings 
     Referring collectively to  FIGS. 1-3 , housing  102  can define a cavity  119  configured to receive spool  108 . For example, housing  102  can include a panel  118  (which can be a back wall of housing  102 , as shown in  FIGS. 1-3 ) and walls  116 . Walls  116  can be, for example, exterior side walls of housing  102 , as shown in  FIGS. 1-3 , in some embodiments. Walls  116  extend from panel  118  such that panel  118  and walls  116  collectively define cavity  119 . In some embodiments, walls  116  extend around substantially the entire perimeter of panel  118 , as shown in  FIGS. 1-3 . In other embodiments, walls  116  extend around only a portion or portions of the perimeter of panel  118 . 
     As shown in  FIGS. 1-3 , panel  118  is planar in some embodiments. In other embodiments, panel  118  is non-planar. As shown in  FIGS. 1-3 , panel  118  can have substantially square shape. In other embodiments, panel  118  can have other suitable shapes such as substantially rectangular shapes. 
     In some embodiments, walls  116  define at least one opening that allows one or more fiber optic cables to enter cavity  119 . For example, walls  116  can define an opening  120  at a corner of housing  102 , as shown in  FIGS. 1-3 . In some embodiments (not shown), walls  116  can define another opening at another corner of housing  102 , for example, at the corner diagonal from opening  120 , or at any other location on walls  116 . 
     Housing  102  can be configured to releasably couple with component module  104  such that an installer can easily and repeatedly attach or detach component module  104  to housing  102 . For example, housing  102  can include a plurality of prongs  112  extending from walls  116 . Prongs  112  are configured to interlock with respective grooves  121  defined by component module  104  to releasably couple component module  104  to housing  102 . In some embodiments, as best seen in  FIG. 3 , housing  102  includes four prongs  112 —two prongs on one wall  116  and two prongs on the opposing wall  116 . In other embodiments (not shown), each wall  116  can include a prong  112 . In other embodiments (not shown), housing  102  includes less than four prongs  112  or more than four prongs  112 . In other embodiments, housing  102  and component module  104  can be releasably coupled together by a friction fit between respective surfaces of housing  102  and component module  104 . 
     Housing  102  can also include a boss  122  extending from panel  118 . Boss  122  is configured to rotatably couple spool  108  to housing  102 . Boss  122  is configured (i.e., shaped and sized) to fit within a corresponding cavity defined by spool  108  such that spool  108  can rotate about an axis defined by boss  122 . As best seen in  FIG. 3 ., boss  122  is located at the center of panel  118 . In other embodiments (not shown), boss  122  is off-centered on panel  118 . 
     Boss  122  can be cylindrical and hollow, as shown in  FIG. 3 , in some embodiments. In some of such embodiments, panel  118  defines an opening  124  aligned with the center of hollow boss  122 . In some applications, opening  124  provides another opening for allowing fiber optic cables to enter cavity  119  of housing  102 . 
     Housing  102  can be configured to be mounted directly to a mounting surface (for example, a wall, pole, or shelf) or can be configured to be mounted to a bracket that is mounted to the mounting surface. In some embodiments, housing  102  includes one or more channels  126  configured to receive a fastener (for example, a bolt, screw, or nail) to secure housing  102  to the mounting surface or mounting bracket. In some embodiments, channels  126  are aligned with openings defined by a mounting bracket to which housing  102  will be coupled. Channels  126  can be located in the corners of housing  102  in some embodiments. 
     In some embodiments, housing  102  also includes one or more cable guides  128  for efficiently containing fiber optic cable stored on spool  108  rotatably coupled to housing  102 . For example, housing  102  can include four cable guides  128  as shown in  FIG. 3 . Cable guides  128  extend from panel  118 . Cable guides  128  include a substantially planar surface facing housing  102 . The planar surface of cable guides  128  is perpendicular to the radial direction of boss  122 . Cable guides  128  can be positioned in each corner of housing  102  as shown in  FIG. 3 , in some embodiments. 
     In some embodiments, housing  102  is the closet component of assembly  100  to the mounting surface and/or mounting bracket. In other embodiments, assembly  100  can include other components, for example, another housing, between housing  102  and the mounting surface. 
     Exemplary Spools 
     Referring collectively to  FIGS. 2, 4-6, and 8 , spool  108  is configured to be rotatably coupled to housing  102  and to store at least a portion of one or more fiber optic cables  180  (shown in  FIG. 8 ). In some embodiments, the one or more fiber optic cables  180  can each have one or more pre-terminated fiber connectors  186  at an end portion  184  of fiber optic cable  180 . Connectors  186  can be configured to be optically couple to one or more adapter  172  (shown in  FIG. 8 ). Connectors  186  can be a subscriber or standard connector (SC connector), a local or Lucent connector (LC), or any combination of SC connectors and LC connectors. In some embodiments, connectors  186  can be 1.times.SC simplex connectors, 1.times.LC duplex connectors, 2.times.SC simplex connectors, 2.times.LC duplex connectors, or any combination thereof. In other embodiments, connectors  186  can be connectors other than SC or LC connectors. 
     Each connector  186  can be releasably and optically coupled to a respective adapter  172  in some embodiments. In some embodiments, connector  186  includes a pre-terminated fiber ferrule, for example, a SC fiber ferrule or LC fiber ferrule. The fiber ferrule of each connector  186  can be configured to be received within adapter  172 , for example, an SC or LC adapter. 
     Spool  108  can include a cylindrical drum  130  configured to store the one or more fiber optic cables  180 . For example, at least a portion of a fiber optic cable  180  can be wrapped around cylindrical drum  130 . In some embodiments, the radius of cylindrical drum  130  is at least the minimum bend radius of the fiber optic cable  180  being stored on drum  130 . In some embodiments, spool  108  is configured to store about 25 feet to about 150 feet of fiber optic cable  180 , for example, about 50 feet. 
     In some embodiments, cylindrical drum  130  is configured to store up to about 50 feet of fiber optic cable. In some embodiments, if more than the maximum cable capacity of cylindrical drum  130 , for example, more than 50 feet of cable, is needed for a particular installation, assembly  100  can be releasably and operatively coupled to an excess cable spool assembly  181  having a second spool  183  that stores cable  185  in excess of the maximum cable capacity of cylindrical drum  130 , for example, the cable portion in excess of about 50 feet. 
       FIGS. 25 and 26  illustrate an exemplary excess cable spool assembly  181  according to an embodiment. In some embodiments, second spool  183  includes an excess cylindrical drum  187  around which excess cable  185  is wound, a first flange  189  extending radially from cylindrical drum  187 , and a second flange  191  extending radially from cylindrical drum  187 . Cylindrical drum  187  is axially between first and second flanges  189  and  191 . In some embodiments, spool  183  is made of a recyclable material, for example, cardboard or a recyclable plastic. In some embodiments, spool  183  is made of a non-recyclable, material. 
     In some embodiments, excess cable spool assembly  181  also includes a handle  193  rotatably attached to second spool  183 . Handle  193  can be removably or fixedly attached to spool  183 . Handle  193  can be made of, for example, plastic or any other suitable material with sufficient rigidity to withstand the forces applied to assembly  181  while paying out excess cable  185 . As shown in  FIGS. 25 and 26 , handle  193  can be coupled to second spool  183  at the bottom center of second spool  183 , for example, at the center of flange  189  and axially aligned with drum  187 . Handle  193  includes a portion  195  configured (i.e., sized and shaped) to allow an installer to grab and control excess cable spool assembly  181  with, for example, one hand. 
     In some embodiments, assembly  100  is releasably attached to flange  191 , and handle  193  is attached to flange  189  opposite the releasably mounted assembly  100 . For example, a portion of assembly  100 , for example, housing  102  or component module  104  of assembly  100 , can be releasably attached to flange  191  using an interference fit connection (for example, a snap fit or press fit connection), an adhesive or bonding agent, or any other suitable releasable coupling mechanism. 
     As shown in  FIG. 26 , for example, a user pays-out (i.e., unwraps around drum  187 ) excess cable  185  by grabbing operating portion  195  with one hand, and then routing excess cable  185  to a desired location, for example, a fiber terminal. As cable  185  is routed to the desired location and while the operating holds operator portion  195  of handle  193 , second cable spool  183  rotates relative to handle  193  to allow easy pay out of excess cable portion  185 . After the excess cable  185  is paid out (for example, after the entire portion of excess cable  185  is removed from spool  183 ), assembly  100  can be decoupled from excess cable spool assembly  181 , and subsequently installed by the installer. 
     Fiber optic cable  180  can be single- or multi-fiber optic cable. In some embodiments, fiber optic cable  180  has a diameter in range of about 2 mm to about 5 mm, and can be as small as 0.9 mm or smaller. In some embodiments, fiber optic cable  180  has a maximum diameter of no more than about 3 mm. In some embodiments, fiber optic cable  180  is single mode or multi-mode fiber. In some embodiments, fiber optic cable  180  is bend insensitive fiber. 
     In some embodiments, spool  108  includes cable retention structures that are configured to keep fiber optic cable  180  wrapped around cylindrical drum  130 . For example, as shown in  FIGS. 2 and 4-6 , the cable retention structures can be a plurality of spaced apart tabs  132  and  134  extending radially outward from the axial ends of cylindrical drum  130 . Tabs  134  extend from the axial end of cylindrical drum  130  closest to housing  102 , and tabs  132  can extend form the axial end of cylindrical drum  130  farthest from housing  102 . Spool  108  can include six tabs  132  and six tabs  134  in some embodiments. In other embodiments, spool  108  can include less than or more than six tabs  132  or tabs  134 . Tabs  132  and tabs  134  can be equally spaced apart about the circumference of drum  130 . In some embodiments, tabs  132  and tabs  134  are aligned relative to each other such that tabs  132  are axially aligned with the gaps between tabs  134 , as best seen in  FIG. 4 . 
     In other embodiments (not shown), the cable retention structures can be solid flanges (as opposed to spaced apart tabs) that extend from the axial ends of cylindrical drum  130 . 
     As best seen in  FIG. 5 , cylindrical drum  130  can define a cavity  136  that has an opening on the axial end closest to housing  102  in some embodiments. Cavity  136  is configured (i.e., shaped and sized) to rotatably receive boss  122  on housing  102 . When boss  122  is received within cavity  136  of spool  108 , spool  108  is rotatably coupled to housing  102  such that spool  108  can rotate relative to housing  102 . Spool  108  can rotate in both clockwise and anti-clockwise directions in some embodiments. Rotation of spool  108  allows a user to easily reel-in (i.e., wrap around drum  130 ) fiber optic cable  180  or pay-out (i.e. unwrap around drum  130 ) fiber optic cable  180  during deployment. 
     In other embodiments (not show), spool  108  can define a boss that is configured to be received in a cavity defined by housing  102  such that spool  108  is rotatably coupled to housing  102 . 
     Spool  108  can also include a panel  138  configured to mount one or more components. 
     In some embodiments, panel  138  is integral with cylindrical drum  130 . Panel  138  can be positioned at the axial end of cylindrical drum  130  farthest from housing  102 . As shown in  FIGS. 2 and 4-6 , panel  138  can be substantially circular and sized to match cylindrical drum  130 . 
     Panel  138  can define one or more openings  140  configured to mate with other components. For example, as shown in  FIGS. 2 and 4-6 , panel  138  can include one opening  140  configured to mate with connector holders configured to store one or more connectors  186  of fiber optic cables  180  stored on cylindrical drum  130 . In some embodiments, opening  140  is substantially rectangular as illustrated. In other embodiments, opening  140  can have other suitable shapes. 
     In some embodiments, the connector holder configured to mate with opening  140  can be either a two connector holder  142  (as shown in  FIG. 9 ) or a four connector holder  202  (as shown in  FIG. 10 ). Connector holders  142  and  202  are each configured to securely and releasably retain the pre-terminated connectorized ends of fiber optic cables  180  stored on spool  108 . Embodiments of connector holders  142  and  202  are explained in more detail below. 
     As best seen in  FIGS. 4 and 6 , panel  138  can also include a fan out retaining structure  144  configured to securely and releasably retain a fan out (not shown) that separates fibers of fiber optic cable  180 . In some embodiments, fan out retaining structure  144  includes a pair of retaining prongs  146  that are configured to cooperatively engage the fan out. In some embodiments, fan out retaining structure  144  is radially aligned with the major axis of rectangular opening  140 . In some embodiments, the fan out coupled to retaining structure  144  is coupled to at least one end of fiber optic cable  180  and separates each fiber of fiber optic cable  180 . The fan out can help prevent the mingling and bundling of loose fibers of fiber optic cable  180 . The fan out can also allow the fibers of the fiber optic cable  180  to be terminated without splicing, and without needing a protective enclosure. 
     In some embodiments, panel  138  also includes one or more cable guides  148 .

Panel  272  and walls  270  can collectively define a cavity  274  configured to closely receive a portion of assembly  100 . In some embodiments, cavity  274  is configured (i.e., shaped and sized) to create a friction fit or a snap fit with assembly  100 . In some embodiment, as shown in  FIG. 20 , panel  272  is substantially square and planar. In some embodiments, walls  270  define or more openings  275 . For example, as shown in  FIG. 20 , walls  270  define two openings  275 . Openings  275  allow an end portion  182  of fiber optic cable  180  to be passed into the wall cavity defined, in part, by mounting surface  264 . 
     Bracket  266  can also include a flange  268  configured to mount flush against mounting surface  264 . Bracket  266  can also include one or more anchors  269  configured to couple bracket  266  to any wall surface. Anchors  269  can be, for example, elongated arms that extend outward from walls  270  to clamp the wall between the elongated arms and flange  268 . 
     Exemplary Cable Routing &amp; Component Configurations 
     Embodiments of cable routing will be described with reference to  FIGS. 7 &amp; 8 , which shows a component module  104  coupled to a housing  102  on which spool  108  is rotatably mounted. In the illustrated embodiment, assembly  100  store one fiber optic cable  180 . Fiber optic cable  180  includes a first end portion  182  and a second end portion  184 . In some embodiments, at least one of first and second end portions  182  and  184  is connectorized—the end portion includes a connector  186  and optionally a boot  188 . Between the two end portions  182  and  184  is an intermediate jacketed portion  190 . 
     Component module  104 , spool  108 , and housing  102  are collectively configured such that a gap  192  is formed between panel  138  of spool  108  and panel  158  of component module  104 . Gap  192  allows a portion of the jacketed portion  190  of cable  180  to pass from cylindrical drum  130  to panel  138  accessible to a user from cavity  157  defined by component module  104 . 
     In some embodiments, a substantially portion of the jacketed portion  190  is stored around cylindrical drum  130  of spool  108 . The portion of cable  180  including first end portion  182  can exit assembly  100  through opening  120  defined by walls  116  of housing  102 . And the portion of cable  180  that includes second end portion  184  can pass from cylindrical drum  130  of spool  108  to the face of panel  138  through the gap  192 . Then this portion of jacketed portion  190  is routed around the periphery of panel  138  through channels  154  defined in part by cable guides  148 . And then end portion  184  having a connector  184  can be stored initially at, for example, connector holder  142 , as shown in  FIG. 8 . 
     Then connector  186  can be decoupled from connector holder  142  and optically coupled to a respective adapter  172  secured by retaining structure  173  on component module  104 . In some embodiments, connector  186  is coupled with jacketed portion  190  of fiber cable  180  via a fan out coupled to retaining structure  144 . 
     Exemplary Applications and Methods of Use 
     In some embodiments, assembly  100  is used in a fiber optic distribution system  300  for FTTx applications as illustrated in  FIGS. 23 and 24 . For example, assembly  100  can be used in fiber to the premises (FTTP) networks and fiber to the business (FTTB) networks. 
     In some FTTP embodiments, a plurality of assemblies  100  can be used to distribute fiber optic cable throughout a multi-unit building  302  having a plurality of separate units  304 . Multi-unit building  302  can be, for example, an apartment building or an office building having one or more separate units  304 , for example, apartments or offices, that need fiber optic cable service. Each separate unit  304  typically needs at least one single fiber connection, and the entire multi-unit building  302  needs a plurality of fibers to service every separate unit  304 . To service multi-unit building  302 , the fiber optic cable provider will run a fiber optic feeder cable  306  to a fiber distribution hub (FDH)  308  that splits the signal transmission. Fiber optic feeder cable  306  can include 1, 12, 24, 48, 72, or any other suitable number of fibers. FDH  308  can be outside or inside the multi-unit building  302 . FDH  308  can be optically coupled to a fiber distribution terminal (FDT)  310  via a multi-fiber optic cable  312  running between FDH  308  and FDT  310 . Multi-fiber cable  312  can have, for example, 12, 24, 48, 72, or 144 fibers, or any other suitable number of fibers. 
     FDT  310  can be any FDT described in U.S. Pat. No. 8,081,857, issued Dec. 20, 2011, and U.S. Pat. No. 8,903,215, issued Dec. 2, 2014. Each of U.S. Pat. Nos. 8,081,857 and 8,903,215 are incorporated herein by reference. For example, FDT  310  can include a rotatable spool that stores a portion of fiber optic cable  310 . The spool of FDT  310  can include a plurality of adapters optically coupled to the fibers of fiber optic cable  312 . 
     In some embodiments, as shown in  FIG. 24 , end portion  182  of fiber optic cable  180  can be optically coupled directly to one adapter of FDT  310  if fiber optic cable  180  is a single-fiber optic cable or to multiple adapters of FDT  310  if fiber optic cable  180  is a multi-fiber cable. In other embodiments, as shown in  FIG. 23 , each of a plurality of single- or multi-fiber optic drop cables  314  can be optically coupled to a respective adapter of FDT  310 , which is optically coupled to one or more fibers of fiber optic cable  312 . Each of fiber optic drop cables  314  can be run towards a respective separate unit  304  of multi-unit building  302 . The fiber optic drop cables  314  can be optically coupled to fiber optic cable  180  of an assembly  100  via an adapter  316 . Adapter  316  can be positioned outside (as shown in  FIG. 23 ) or inside (not shown) of a separate unit  304  of multi-unit building  302 . Each of the respective separate units  304  can have an end-user fiber-optic device  318  that translates the fiber cable signal into useful information. Assembly  100  optically couples fiber-optic device  318  to the respective fiber optic drop cable  314  running from FDT  310  (outside of separate unit  304 ) in some embodiments. 
     In some embodiments, fiber optic cable  180  stored on spool  108  is paid out (i.e., un wrapped from drum  130 ) by pulling end portion  182  of fiber optic cable  180  away from assembly  100 . As fiber optic cable  180  is paid out, spool  108  rotates relative to housing  102  while component module  104  remains stationary. Fiber optic cable  180  can be easily paid out from assembly  100  while mounted to a mounting location or while removed from the mounting location. Fiber optic cable  180  is paid out until end portion  182  reaches the end of the single fiber drop from an FDT. Rotation of spool  108  of assembly  100  allows an installer to easily achieve the need length of fiber optic cable  180  to reach the end of fiber optic cable  314  while efficiently storing the excess cable on cylindrical drum  130 . End portion  182  is then optically coupled to the end of fiber optic cable drop  314 . For example, end portion  182  of fiber optic cable  180  can include a connector, and the end of fiber optic cable  314  can include a connector that can be optically coupled to the connector at end portion  182  using adapter  316 . 
     In some embodiments, assembly  100  is used in new construction of multi-unit buildings and in applications in which a multi-unit building is being retrofitted with a FTTx network. 
     The fiber-optic device in the separate unit can then be optically coupled to fiber optic cable  180  via adapter  172  on component module  104 . For example, a patch fiber optic cable  320  optically coupled to end-user fiber optic device  318  can be coupled to adapter  172  accessible to the installer through opening  162 , thereby optically coupling end-user fiber optic device  318  to the network.
