     BACKGROUND 
     This disclosure relates generally to fiber optic equipment, and in particular, to a fiber optic apparatus to provide retrofit fiber optic connectivity. 
     To improve network performance, communication and data networks are increasingly employing optical fiber. A fiber optic network provides optical signals over a distribution network comprised of fiber optic cables. The benefits of optical fiber are well known and include higher signal-to-noise ratios and increased bandwidth. Many areas are transitioning from copper to fiber for these reasons. In a fiber optic network, fiber optic connectivity and subscriber connection maintenance may be housed in a fiber optic cabinet, such as for example a fiber distribution hub. 
     In this regard,  FIGS.  1 A- 1 B  are exemplary views of a typical fiber optic cabinet  100 . Referring to  FIG.  1 A , the fiber optic cabinet  100  includes a housing  102  defining an interior  104  with fiber optic equipment  106  positioned within the interior  104  of the housing  102 . In particular, the fiber optic equipment  106  includes a distribution panel  108  to connect and manage outgoing lines to a subscriber, a feeder panel  110  to connect and manage incoming lines from a provider, and a plurality of splitter modules  112  to connect the feeder panel  110  to the distribution panel  108 . The distribution panel  108  is positioned toward a left side of the housing  102  and the feeder panel  110  and the splitter modules  112  are positioned toward a right side of the housing  102 . The outgoing and incoming lines are connected to the distribution panel  108  and the feeder panel  110  by cables positioned behind the distribution panel  108  and/or the feeder panel  110 . The splitter modules  112  are mounted on a sliding shelf  114 , such that moving the shelf  114  forward and/or out of the interior  104  of the fiber optic cabinet  100  provides access to multiple splitter modules  112  per shelf  114 .  FIG.  1 B  is an exemplary perspective view of cabling  116  mounted within the typical fiber optic cabinet  100 . In particular, the cabling  116  is positioned on the shelf  114  within the housing  102  of the fiber optic cabinet  100 . 
     Such fiber optic cabinets  100  are typically configured with dimensional flexibility to accommodate various fiber optic equipment  106  and/or configurations thereof. For example, the width of the housing  102  may be increased to accommodate a larger distribution panel  108 , more splitter modules  112 , etc. The depth of the housing  102  may be increased to accommodate more cabling  116 , etc. 
     However, transitioning from copper to fiber may be challenging or unavailable for certain areas if a fiber optic cabinet must be installed. For example, deployment of a fiber optic cabinet  100  may not be possible in areas that are topographically challenging, such as with narrow roads, no sidewalks, etc., even though those areas may include a cabinet housing electrical equipment (e.g., copper). In such cases, customers with a copper infrastructure may have no path to deployment of fiber using typical fiber optic cabinets  100 . Even in cases where a fiber optic cabinet may be installed, doing so may be expensive, time consuming, and/or filled with regulatory hurdles. 
     Accordingly, there is a desire for an easy and effective transition from copper to fiber, particularly one that utilizes existing infrastructure. 
     No admission is made that any reference cited herein constitutes prior art. Applicant expressly reserves the right to challenge the accuracy and pertinency of any cited documents.

In certain embodiments, the fiber optic apparatus  200  has a height H 1  between 40 inches and 60 inches, and is configured to provide fiber optic connections for up 432 distribution fibers in some embodiments. In other embodiments, the fiber optic apparatus is configured to provide connections for up to 864 distribution fibers when installing two fiber optic apparatuses  200  in a back to back or side by side configuration within the telecommunications cabinet  202 . The fiber optic apparatus  200  is configured for retrofit deployment within a telecommunications cabinet  202  (see  FIG.  2   ) for easy transition from copper or electrical to fiber, to take advantage of existing copper infrastructure, to minimize time and cost of installation of fiber optic equipment, to avoid construction permits and other regulatory requirements, etc. 
     The support structure  300  of the fiber optic apparatus  200  includes a frame body  204 . The frame body  204  includes a first end  302 A (also referred to as a top end), a second end  302 B (also referred to as bottom end) opposite the first end  302 A, a first side  304 A (also referred to as a left side) that extends between the top end  302 A and the bottom end  302 B, and a second side  304 B (also referred to as a right side) that extends between the top end  302 A and the bottom end  302 B and opposite to the first side  304 A. The frame body  204  further includes a first body  306 A (also referred to as an upper body) positioned toward the top end  302 A and a second body  306 B (also referred to as a lower body) positioned toward the bottom end  302 B. The upper body  306 A supports and mounts the fiber optic connection array  206  (explained in more detail below). Directional terms, such as “top,” “bottom,” “upper,” “lower,” “left,” “right,” “medial,” “distal,” etc. are used for non-limiting illustrative purposes only. 
     The frame body  204  further includes a rear protective cover  308  (also referred to as a back protective cover) to selectively enclose at least a portion of the fiber optic cable assembly  208  (explained in more detail below). In particular, the rear protective cover  308  may be pivotally (e.g., hingedly) and/or removably attached to the upper body  306 A. The frame body  204  further includes a top installation bracket  310 A positioned at the top end  302 A of the frame body  204  and a bottom installation bracket  310 B positioned at the bottom end  302 B of the frame body  204 . The top installation bracket  310 A and the bottom installation bracket  310 B mount the fiber optic apparatus  200  to the telecommunications cabinet  202  (explained in more detail below). The bottom installation bracket  310 B includes a left hook  312 A forwardly extending from a left side of the bottom installation bracket  310 B and a right hook  312 B forwardly extending from a right side of the bottom installation bracket  310 B. The left and right hooks  312 A,  312 B facilitate mounting and selective pivoting of the fiber optic apparatus  200  relative to the telecommunications cabinet  202  for selective access to the area of the telecommunications cabinet  202  directly behind the fiber optic apparatus  200 . 
     The lower body  306 B includes a back wall  314 , a first sidewall  318 A (also referred to as a left sidewall) forwardly extending from a left side of the back wall  314  and a second sidewall  318 B (also referred to as a right sidewall) opposite the left sidewall  318 A and forwardly extending from a right side of the back wall  314 . The back wall  314  may define an opening  316  for cross-connection of fiber optic splitter modules  212  between multiple fiber optic apparatuses  200  set up in a back to back orientation. The lower body  306 B includes an upper wall  320  extending between the left and right sidewalls  318 A,  318 B from a top thereof. The lower body  306 B further includes a bottom container  322  (also referred to as slack storage) extending between the left and right sidewalls  318 A,  318 B from a bottom thereof. The bottom container  322  is configured to receive and hold slack of the splitter output cables  218 B from the fiber optic splitter modules  212  when the fiber optic splitter modules  212  are mounted to the lower body  306 B (explained in more detail below). 
     A splitter installation  324  includes a splitter mount  210  extending from the left side  304 A of the fiber optic apparatus  200  to the right side  304 B of the fiber optic apparatus  200  and positioned between the left and right sidewalls  318 A,  318 B of the lower body  306 B, and between the upper wall  320  of the lower body  306 B and the bottom container  322 . The splitter mount  210  is configured for mounting of one or more fiber optic splitter modules  212  thereto. The splitter mount  210  is obliquely angled relative to the frame body  204  and/or the bottom container  322  to direct the slack from the splitter output cables  218 B of the fiber optic splitter modules  212  into the bottom container  322 . Each fiber optic splitter module  212  includes a housing  326 , at least one splitter input cable  218 A (see  FIG.  4 A ) extending from a first end (also referred to as a top) of the housing  326 , and one or more splitter output cables  218 B (see  FIG.  4 A ) extending from a second end (also referred to as a bottom) of the housing  326 . It is noted that the terms “input” and “output” are for non-limiting illustrative purposes only, and all cables are bidirectional unless otherwise noted. By way of example, each fiber optic splitter module  212  may provide thirty-two splitter output cables  218 B for each splitter input cable  218 A. In other embodiments, each fiber optic splitter module  212  may include more or less than thirty-two output cables  218 B (e.g., 1×4 splitter modules, 1×8 splitter modules, and 1×16 splitter modules). The fiber optic splitter modules  212  are adjacently mounted to one another on the splitter mount  210  from the left side  304 A of the frame body  204  to the right side  304 B of the frame body  204 . In this way, the splitter mount  210  may be configured to mount between one and twenty fiber optic splitter modules  212  (e.g., fourteen fiber optic splitter modules  212 ). In some embodiments, the splitter mount  210  may be configured to mount more than twenty fiber optic splitter modules  212 . When mounted, the splitter input cables  218 A extend upwardly and the splitter output cables  218 B extend downwardly, as illustrated in  FIG.  4 A . The fiber optic splitter modules  212  are mounted at an angle relative to the frame body  204  so that the slack of the downwardly extending splitter output cables  218 B is set farther back from a front of the fiber optic apparatus  200 . In other words, the fiber optic splitter modules  212  are obliquely angled so that the downwardly extending splitter output cables  218 B fall closer to a back of the bottom container  322  of the fiber optic apparatus  200 , to facilitate organization. 
     Referring momentarily to  FIG.  5 A , the splitter installation  324  further includes a connector parking panel  226  for removably mounting one or more parking blocks  328 . The connector parking panel  226  extends from the left side  304 A of the fiber optic apparatus  200  to the right side  304 B of the fiber optic apparatus  200 . Each parking block  328  mounts one or more splitter output connectors  230 B, and in particular, splitter output connectors  230 B not connected to the fiber optic connection array  206 . The parking block  328  is removably attachable to the connector parking panel  226 . In this way, the parking block  328  can attach multiple splitter output connectors  230 B, and provide easy access to such splitter output connectors  230 B. 
     Referring again to  FIGS.  3 A- 3 B , the connector parking panel  226  is positioned above the splitter mount  210 . In this way, the extra slack from the unconnected splitter output cables  218 B (see  FIG.  4 A ) of the fiber optic splitter modules  212  are kept out of the way of the rest of the fiber optic apparatus  200 , but remain easily accessible for subsequent connection of the splitter output connectors  230 B (see  FIG.  5 A ) of the splitter output cables  218 B to the fiber optic connection array  206  (explained in more detail below). 
     The fiber optic connection array  206  includes a feeder panel  214 , a distribution panel  220 , and a pass-through panel  330 . Each of the feeder panel  214 , the distribution panel  220 , and the pass-through panel  330  extend from the left side  304 A of the fiber optic apparatus  200  to the right side  304 B of the fiber optic apparatus  200 . The feeder panel  214 , the distribution panel  220 , and the pass-through panel  330  may be separate panels that are each separately coupled to the frame body  204  or one or more of the feeder panel  214 , the distribution panel  220 , and the pass-through panel  330  may be configured as a single, unitary component that is then coupled to the frame body  204 . In other embodiments, one or more of the feeder panel  214 , the distribution panel  220 , and the pass-through panel  330  may be unitarily formed with the frame body  204 . 
     The feeder panel  214  is positioned above the connector parking panel  226  such that the connector parking panel  226  is positioned between the feeder panel  214  and the splitter mount  210 . The feeder panel  214  includes a plurality of feeder ports  216  configured to receive feeder port connector adapters  217  (see  FIG.  4 A ) for connection of the splitter input connectors  230 A (see  FIG.  5 A ) of the splitter input cables  218 A of the fiber optic splitter modules  212  thereto. Accordingly, it is advantageous to position the feeder panel  214  proximate to the fiber optic splitter modules  212 . Each of the feeder port connector adapters  217  of the feeder ports  216  is configured for optical communication with a network provider (e.g., central office). The feeder port connector adapters  217  of the feeder ports  216  can be configured in columns and rows for organizational purposes. 
     The distribution panel  220  is positioned above the feeder panel  214  such that the feeder panel  214  is positioned between the connector parking panel  226  and the distribution panel  220 . The distribution panel  220  includes a plurality of distribution ports  222  configured to receive distribution port connector adapters  223  (see  FIG.  4 A ) for connection of the splitter output connectors  230 B of the splitter output cables  218 B of the fiber optic splitter modules  212  thereto. Each of the distribution port connector adapters  223  (see  FIG.  4 A ) of the distribution ports  222  is configured for optical communication with a subscriber (e.g., home subscriber). The distribution port connector adapters  223  of the distribution ports  222  can be configured in columns and rows for organizational purposes. 
     The pass-through panel  330  is positioned above the distribution panel  220  such that the distribution panel  220  is positioned between the feeder panel  214  and the pass-through panel  330 . The pass-through panel  330  includes a plurality of pass-through ports  332  configured to receive pass-through port connector adapters  333  (see  FIG.  4 A ) for direct connections between the feeder port connector adapters  217  (see  FIG.  4 A ) of the feeder ports  216  of the feeder panel  214  and the pass-through port connector adapters  333  (see  FIG.  4 A ) of the pass-through ports  332 . Thus, the pass-through panel  330  provides optical fiber connections with larger bandwidth than those of the distribution ports  222  of the distribution panel  220 . Each of the pass-through port connector adapters  333  of the pass-through ports  332  is configured for optical communication with a subscriber (e.g., business subscriber). The pass-through port connector adapters  333  of the pass-through ports  332  can be configured in columns and rows for organizational purposes. 
     The support structure  300  of the fiber optic apparatus  200  further includes left and right routing guides  224 A,  224 B positioned, respectively, along the left side  304 A and the right side  304 B of the fiber optic apparatus  200 . The left and right routing guides  224 A,  224 B are vertically oriented and organize the splitter output cables  218 B of the fiber optic splitter modules  212  connected to fiber optic connection array  206  (explained in more detail below). The left routing guide  224 A includes a u-shaped bracket  334  having a back wall  336 , a medial wall  338 A (also referred to as a right wall) forwardly extending from an edge of the back wall  336  proximate a center of the fiber optic apparatus  200 , and a distal wall  338 B (also referred to as a left wall) forwardly extending from an edge of the back wall  336  away from the center of the fiber optic apparatus  200 . The back wall  336 , medial wall  338 A, and distal wall  338 B define a vertical routing channel  342  (with an open top and an open bottom) for routing of the splitter output cables  218 B (see  FIG.  4 A ) of the fiber optic splitter modules  212  therethrough. The back wall  336  of the left routing guide  224 A is attached at a front surface of the frame body  204  and/or the fiber optic connection array  206 . In this way, the left routing guide  224 A forwardly extends from the frame body  204  and/or the fiber optic connection array  206  (e.g., feeder ports  216  of the feeder panel  214 , distribution ports  222  of the distribution panel  220 , pass-through ports  332  of the pass-through panel  330 ) to provide routing access of the splitter output cables  218 B (see  FIG.  4 A ) up through the left routing guide  224 A and inwardly to their respective port (e.g., feeder ports  216 , distribution ports  222 , pass-through ports  332 ), as explained in more detail below. 
     The left routing guide  224 A further includes a front cover  344  pivotally (also referred to as hingedly) attached to a distal wall  338 B of the u-shaped bracket  334 . Accordingly, the front cover  344  is movable between a closed position and an open position. In the closed position, the front cover  344  extends between the medial wall  338 A and the distal wall  338 B enclosing the vertical routing channel  342 . The medial wall  338 A includes a plurality of fiber guide slots  340  (the fiber guide slots  340  of the medial wall  338 A of the left routing guide  224 A are hidden in  FIG.  3 A  but are similar to the fiber guide slots  340  of the medial wall  338 A of the right routing guide  224 B, which is visible in  FIG.  3 A ) aligned along a vertical length of the medial wall  338 A for insertion of one or more splitter output cables  218 B (see  FIG.  4 A ) therein, such that the one or more splitter output cables  218 B (see  FIG.  4 A ) extend out of the vertical routing channel  342  to the respective port (e.g., distribution port  222 ). Thus, each fiber guide slot  340  is positioned adjacent to a row of distribution ports  222  in the distribution panel  220 . For example, referring momentarily to  FIG.  4 A , the splitter output cables  218 B are directed from the housing  326  of each the fiber optic splitter module  212  downwardly into the bottom container  322 , to the left side of the bottom container  322 , up the left side of the frame body  204  through a bottom opening of the vertical routing channel  342  of the left routing guide  224 A and then inwardly through a fiber guide slot  340  (see  FIG.  3 A ) to one of the distribution port connector adapters  223  of the distribution ports  222  (see  FIG.  3 A ) adjacent to the fiber guide slot  340  (see  FIG.  3 A ). This arrangement organizes the splitter output cables  218 B and keeps the distribution panel  220  open and accessible. 
     Referring again to  FIGS.  3 A and  3 B , in certain embodiments a plurality of left lower fiber guide slots  346 A may be positioned on a left side of the connector parking panel  226  for securement of splitter output cables  218 B (see  FIG.  4 A ) and/or other cables in physical connection with the distribution port connector adapters  223  (see  FIG.  4 A ) of the feeder ports  216  of the feeder panel  214 , as the left routing guide  224 A may only extend up to but not past the feeder panel  214  to leave sufficient room for mounting the top installation bracket  310 A. 
     Similarly, the right routing guide  224 B includes a u-shaped bracket  334  having a back wall  336 , a medial wall  338 A (also referred to as a left wall) forwardly extending from an edge of the back wall  336  proximate a center of the fiber optic apparatus  200 , and a distal wall  338 B (also referred to as a right wall) forwardly extending from an edge of the back wall  336  away from the center of the fiber optic apparatus  200 . The back wall  336 , medial wall  338 A, and distal wall  338 B define a vertical routing channel  342  (with an open top and an open bottom) for routing of the splitter output cables  218 B (see  FIG.  4 A ) of the fiber optic splitter modules  212  therethrough. The back wall  336  of the right routing guide  224 B is attached at a front surface of the frame body  204  and/or the fiber optic connection array  206 . In this way, the right routing guide  224 B forwardly extends from the frame body  204  and/or the fiber optic connection array  206  (e.g., feeder ports  216  of the feeder panel  214 , distribution ports  222  of the distribution panel  220 , pass-through ports  332  of the pass-through panel  330 ) to provide routing access of the splitter output cables  218 B up through the right routing guide  224 B and inwardly to their respective port (e.g., feeder ports  216 , distribution ports  222 , pass-through ports  332 ), as explained in more detail below. 
     The right routing guide  224 B further includes a front cover  344  pivotally (also referred to as hingedly) attached to a distal wall  338 B of the u-shaped bracket  334 . Accordingly, the front cover  344  is movable between a closed position and an open position. In the closed position, the front cover  344  extends between the medial wall  338 A and the distal wall  338 B enclosing the vertical routing channel  342 . The medial wall  338 A includes a plurality of fiber guide slots  340  aligned along a vertical length of the medial wall  338 A for insertion of one or more splitter output cables  218 B therein, such that the one or more splitter output cables  218 B extend out of the vertical routing channel  342  to the respective port (e.g., distribution port  222 ). Thus, each fiber guide slot  340  is positioned adjacent to a row of distribution ports  222  in the distribution panel  220 . Referring momentarily to  FIG.  4 A , the splitter output cables  218 B are directed from the housing  326  of the fiber optic splitter module  212  downwardly into the bottom container  322 , to the right side of the bottom container  322 , up the right side of the frame body  204  through a bottom opening of the vertical routing channel  342  of the right routing guide  224 B, and then inwardly through a fiber guide slot  340  (see also  FIG.  4 A ) to one of the distribution port connector adapters  223  of the distribution ports  222  adjacent to the fiber guide slot  340 . This arrangement organizes the splitter output cables  218 B and keeps the distribution panel  220  open and accessible. 
     Referring again to  FIGS.  3 A and  3 B , in certain embodiments a plurality of right lower fiber guide slots  346 B may be positioned on a right side of the connector parking panel  226  for securement of splitter output cables  218 B and/or other cables in physical connection with the feeder ports  216  of the feeder panel  214 , as the right routing guide  224 B may only extend up to but not past the feeder panel  214  to leave sufficient room for mounting the top installation bracket  310 A. 
       FIGS.  4 A- 4 B  are exemplary views of the fiber optic apparatus  200  of  FIGS.  2 - 3 B  illustrating wiring thereof. When installed in a telecommunications cabinet  202 , the fiber optic cable assembly  208  of the fiber optic apparatus  200  provides optical communication and fiber optic routing management. In particular, the fiber optic cable assembly  208  includes side wiring  400 , back wiring  402 , and front wiring  404 . Side wiring  400  includes input fibers  406 A that may be in optical communication with a network provider (e.g., from a central office) and output fibers  406 B that may be in optical communication with a subscriber (e.g., home, business, etc.). The side wiring  400  further includes an armored tail  408  attached to and downwardly extending from the detachable strain relief bracket  242  downwardly to a ground port. The side wiring  400  further includes flexible tubing  240  attached to and upwardly extending from the detachable strain relief bracket  242  to the frame body  204  of the fiber optic apparatus  200 . In certain embodiments, the flexible tubing  240  comprises expando mesh or any other flexible material. Accordingly, the side wiring  400  provides optical communication between the fiber optic apparatus  200  and a splice box  410 . 
     The back wiring  402  includes a plurality of RFK sets  232 A- 232 C providing optical communication between the side wiring  400  and the fiber optic connection array  206  (e.g., the feeder port connector adapters  217  of the feeder ports  216 , the distribution port connector adapters  223  of the distribution ports  222 , and/or the pass-through port connector adapters  333  of the pass-through ports  332 ). The front wiring  404  includes fiber optic splitter modules  212  and provides optical communication between the feeder port connector adapters  217  of the feeder ports  216  of the feeder panel  214 , the distribution port connector adapters  223  of the distribution ports  222  of the distribution panel  220 , and/or the pass-through port connector adapters  333  of the pass-through ports  332  of the pass-through panel  330 . 
     The general optical signal (and associated wiring) flows, as an example, from a provider to the splice box  410 , and then proceeds from the splice box  410  through input fibers  406 A to the back wiring  402 , and in particular to the input cables  236 A of the RFK sets  232 A- 232 C. The optical signal then proceeds through the output cables  236 B of the RFK sets  232 A- 232 C to a backside of the feeder port connector adapters  217  of the feeder ports  216  and/or the pass-through port connector adapters  333  of the pass-through ports  332 . The front side of at least some of the feeder port connector adapters  217  of the feeder ports  216  may be connected (e.g., physically connected) to the splitter input connector  230 A (see  FIG.  5 A ) of the splitter input cables  218 A of at least one of the fiber optic splitter modules  212 . The optical signal then proceeds through the fiber optic splitter module  212  to the splitter output cables  218 B. At least some of the splitter output connectors  230 B (see  FIG.  2   ) of the splitter output cables  218 B are connected (e.g., physically connected) to a frontside of the distribution port connector adapters  223  of the distribution ports  222  of the distribution panel  220 . A backside of the distribution port connector adapters  223  of the distribution ports  222  of the distribution panel  220  is connected (e.g., physically connected) to at least a portion of the RFK sets  232 A- 232 C which are then connected to the output fibers  406 B. The optical signal then flows through the cables in the flexible tubing  240  to the armored tail  408  to the subscriber premises (e.g., home, business, etc.). 
     The upper body  306 A includes a lower back shelf  412  for mounting the plurality of RFK sets  232 A- 232 C, explained in more detail below. The lower back shelf  412  is positioned between the splitter mount  210  and the feeder panel  214 . The upper body  306 A further includes an upper back shelf  414  for horizontally routing output cables  236 B of the RFK sets  232 A- 232 C. The upper back shelf  414  is positioned above the plurality of RFK sets  232 A- 232 C and below the feeder panel  214 . Further, the upper back shelf  414  includes a horizontal routing guide  416  embodied as a plurality of routing clips  418 . The plurality of routing clips  418  are attached to a lower surface of the upper back shelf  414  and downwardly extending therefrom. The plurality of routing clips  418  retain at least a portion of the output cables  236 B of the plurality of RFK sets  232 A- 232 C to route the output cables  236 B of the RFK sets  232 A- 232 C toward the right side  304 B of the fiber optic apparatus  200 . 
     The upper body  306 A of the frame body  204  of the support structure  300  of the fiber optic apparatus  200  also includes a vertical side flange  420  vertically extending along a right side  304 B of the frame body  204 . The vertical side flange  420  includes a back vertical routing guide  422  embodied as a plurality of routing clips  424  for routing fibers between the RFK sets  232 A- 232 C and the feeder ports  216 , distribution ports  222 , and/or pass-through ports  332 . In particular, the output cables  236 B of the RFK sets  232 A- 232 C are routed upwardly along the vertical side flange  420  and then toward the left side  304 A to their respective feeder port connector adapter  217  of the feeder port  216 , distribution port connector adapter  223  of the distribution port  222 , or pass-through port connector adapter  333  of the pass-through port  332 . 
       FIGS.  5 A- 5 B  are views of the connector parking panel  226 . As mentioned above, the connector parking panel  226  is configured for removably mounting one or more parking blocks  328 , which are shown mounted to the connector parking panel  226  in  FIG.  5 A  and are removed from the connector parking panel in  FIG.  5 B . The connector parking panel  226  includes a left bracket  500 A, a right bracket  500 B, and a plate  502  extending between the left bracket  500 A and the right bracket  500 B. In this way, the plate  502  is offset from the frame body  204  and defines a vertical channel  504  therebetween. This arrangement provides clearance for splitter input cables  218 A to extend from the fiber optic splitter modules  212  mounted on the splitter mount  210  to the feeder port connector adapters  217  in the feeder ports  216  of the feeder panel  214 , as the connector parking panel  226  is positioned between the splitter mount  210  and the feeder panel  214 . The plate  502  is hingedly connected along a left side thereof to the left bracket  500 A to provide access to the vertical channel  504  behind the plate  502 . 
     The splitter installation  324  further includes a plurality of front routing clips  506  horizontally aligned. The front routing clips  506  are positioned above the connector parking panel  226  and between the connector parking panel  226  and the feeder panel  214 . The front routing clips  506  are configured to route the splitter input cables  218 A from the fiber optic splitter modules  212  to the feeder panel  214 , and/or to retain the unconnected splitter input connectors  230 A for easy access for subsequent connection of the splitter input connectors  230 A. 
     The plate  502  of the connector parking panel  226  includes one or more recessed mount surface  228  obliquely angled relative to a front surface of the plate  502 . Each recessed mount surface  228  includes a plurality of apertures  508  for mounting the connector parking block  328  thereto. Each connector parking block  328  includes one or more prongs  510  for attaching the connector parking block  328  to the connector parking panel  226 . The connector parking block  328  is removably attachable to the connector parking panel  226  by insertion of the prongs  510  of the connector parking block  328  into the apertures  508  of the connector parking panel  226 . In this way, the recessed mount surface  228  is obliquely angled so that when the connector parking block  328  is attached to the recessed mount surface  228 , the connector parking block  328  and associated splitter input connectors  230 A are downwardly angled. This arrangement reduces the depth of the connector parking block  328  and associated splitter input connectors  230 A, and accordingly, reduces the depth of the fiber optic apparatus  200 . 
       FIGS.  6 A- 6 C  are views of the fiber optic apparatus  200  of  FIGS.  2 - 5 B  illustrating mounting of an RFK set  232 C to the fiber optic apparatus  200 . This mounting methodology also applies to the RFK sets  232 A,  232 B which are not illustrated. The upper body  306 A of the fiber optic apparatus  200  includes a plurality of RFK mounts  600  attached to the lower back shelf  412  of the upper body  306 A of the frame body  204  of the support structure  300  of the fiber optic apparatus  200 . Each of the plurality of RFK mounts  600  includes a base  602  with a plurality of legs  604 A- 606 B downwardly extending therefrom. The plurality of legs  604 A- 606 B offset the base  602  of the RFK mount  600  from the lower back shelf  412  thereby providing sufficient room for routing of input cable  236 A for adjacent RFK sets  232 A- 232 C underneath. In particular, the plurality of legs  604 A- 606 B includes a front left leg  604 A downwardly extending at a front left corner of the base  602 , a back left leg  606 A downwardly extending at a back left corner of the base  602 , a front right leg  604 B downwardly extending at a front left corner of the base  602 , a back right leg  606 B downwardly extending at a back left corner of the base  602 . Positioning of the plurality of legs  604 A- 606 B at corners of the base  602  provides sufficient room between them (e.g., between the front left leg  604 A and the back left leg  606 A, between the front right leg  604 B and the back right leg  606 B) to route the input cable  236 A for adjacent RFK sets  232 A- 232 C therebetween. Each of the front left and right legs  604 A,  604 B comprises a foot  608 A,  608 B for stability of the RFK mount  600 . Each of the back left and right legs  606 A,  606 B comprises a foot  610 A,  610 B, each with a hole  612 A,  612 B in it for mounting the RFK mount  600  to the lower back shelf  412 . This arrangement facilitates stability and easy assembly of the RFK mounts  600  to the lower back shelf  412 . 
     The RFK mounts  600  further comprise a left post  614 A upwardly extending at a left side of the base  602  and a right post  614 B upwardly extending at a right side of the base  602 . The left and right posts  614 A,  614 B horizontally retain the housings  238  of the RFKs  234  on the base  602 . The RFK mounts  600  further comprise a front wall  616 A upwardly extending at a front side of the base  602  and a back wall upwardly extending at a back side of the base  602 . The front and back walls  616 A,  616 B retain the housings  238  of the RFKs  234  on the base  602 . Further, each of the front and back walls  616 A,  616 B may define a plurality of holes  618  for inserting a fastener (embodied as a cable tie  620 ) across a top of the front and back walls  616 A,  616 B, thereby vertically retaining the housings  238  of the RFKs  234  between the front and back walls  616 A,  616 B. Additionally, the front and back walls  616 A,  616 B may be configured to mount multiple stacks (also referred to as columns) of housings  238  of RFKs  234 . 
       FIG.  7    is a partial side view of the fiber optic apparatus  200  of  FIGS.  2 - 6 C  illustrating a detachable strain relief bracket  242  (but omitting side wiring  400 ). The detachable strain relief bracket  242  includes a body  700  with a flange  702  downwardly extending from the body  700 . The flange  702  includes a plurality of holes  704  for receiving a fastener (embodied as a screw) therein for mounting the detachable strain relief bracket  242  to the right sidewall  318 B. The detachable strain relief bracket  242  further includes a plurality of prongs  706  upwardly extending from the body  700 . Each of the plurality of prongs  706  includes one or more left nubs  708 A extending from a left side of the prong  706  and one or more right nubs  708 B extending from a right side of the prong  706 . The prongs  706  provide a surface for fastening the armored tail  408  and flexible tubing  240  to the detachable strain relief bracket  242 , such as by cable ties (explained in more detail below). The left and right nubs  708 A,  708 B prevent the cable ties from slipping upward or downward on the prong  706  (discussed in more detail below). 
       FIG.  8 A  is a view of the fiber optic apparatus  200  of  FIGS.  2 - 7    mounted within a telecommunications cabinet  202  of  FIG.  2   . The telecommunications cabinet  202  is attached to a secured surface  802 . The telecommunications cabinet  202  includes electrical copper wiring components  800  and the fiber optic apparatus  200  mounted between a top rail  804  and a bottom rail  806  of the telecommunications cabinet  202 .

In some embodiments, the detachable strain relief bracket  242  may initially be coupled to the frame body  204  for shipment and may then be removed from the frame body  204  for installation onto the bottom rail  806 . 
       FIG.  8 B  is a magnified view of the strain relief bracket  242  coupled to the bottom rail  806 . When the strain relief bracket  242  is coupled to the bottom rail  806 , the strain relief bracket  242  is positioned over the distribution cable conduit  808  such that the armored tail  408  is inserted into the distribution cable conduit  808 . This arrangement provides an installer with flexibility in retrofitting the fiber optic apparatus  200  within the telecommunications cabinet  202 , as there may be some offset between mountable locations of the fiber optic apparatus  200  on the telecommunications cabinet  202  and the location of the distribution cable conduit  808  relative to those mountable locations. Thus, the detachable strain relief bracket  242  may be mounted to the left or right side of the fiber optic apparatus  200  when mounted within the telecommunications cabinet  202 . An embodiment in which the detachable strain relief bracket  242  is mounted to the right side of the fiber optic apparatus  200  is illustrated in  FIG.  8 A . 
     Referring momentarily to  FIG.  3 A , as noted above the bottom installation bracket  310 B includes left and right hooks  312 A,  312 B. Referring again to  FIG.  8 B , these left and right hooks  312 A,  312 B may be inserted into slots  810  in the bottom rail  806  and retained therein. Accordingly, when the top installation bracket  310 A is unsecured from the top rail  804  of the telecommunications cabinet  202 , the fiber optic apparatus  200  is forwardly pivotable to provide access to the area of the telecommunications cabinet  202  directly behind the fiber optic apparatus  200 , as shown in  FIG.  8 C . Referring now to  FIG.  8 C , the upper body  306 A of the fiber optic apparatus  200  may include a support bracket  812  including a tab  814  at a back thereof attached to the top installation bracket  310 A. A cable  815  may be attached between the top rail  804  and the tab  814  such that the operator may release the fiber optic apparatus  200  in the open position without the fiber optic apparatus  200  touching the ground. Further, the elongated length of the flexible tubing  240  (see  FIG.  2   ) allows for the fiber optic apparatus  200  to pivot forward, even when the detachable strain relief bracket  242  is mounted to the bottom rail  806 . 
       FIGS.  9 A- 9 C  are exemplary views of another embodiment of the fiber optic apparatus  200  of  FIGS.  2 - 8 C . The fiber optic apparatus  900  includes all the same features as those described above for the fiber optic apparatus  200 , except where otherwise noted. The fiber optic apparatus  900  is configured to have a lower profile (also referred to as a decreased height) compared to the fiber optic apparatus  200  of  FIGS.  2 - 8 C , such as between 25 and 35 inches. In some embodiments, the fiber optic apparatus  900  may provide for fewer distribution ports  222  and therefore fewer distribution port connector adapters  223  (see, e.g.,  FIG.  4 A ). For example, in some embodiments, the fiber optic apparatus  900  may include capacity for up to 288 fiber optic adapters. 
     In particular, the fiber optic apparatus  900  includes a splitter mount  902 , but the splitter mount  902  is not angled, and the fiber optic apparatus  900  does not include a bottom container  322 . Further, a connector parking panel  904  is positioned at a top of the fiber optic apparatus  900  above the pass-through panel  330 . Further, the connector parking panel  904  does not include a recessed mounting surface, and the parking blocks  328  are mounted perpendicularly to the connector parking panel  904 . Although the recessed mounting surface could be used, it is not needed because the connector parking panel  904  is not forwardly offset from the frame body  204  as in the fiber optic apparatus of  FIGS.  2 - 8 C . 
       FIG.  10    is an exemplary front view of a frame body and fiber optic connection array of the fiber optic apparatus of  FIGS.  9 A- 9 C . In particular the splitter mount  902  is configured for mounting a plurality of LS splitters.  FIG.  11    is an exemplary front view of another embodiment of a frame body and fiber optic connection array of the fiber optic apparatus of  FIGS.  9 A- 9 C . In this embodiment, the splitter mount  1102  includes a left section  1104 A configured for mounting slim splitters, and a right section  1104 B with three parking block slots  1106  each configured for mounting a connector parking block  328  (see  FIG.  5 A ). 
     In some examples, an internal volume of the telecommunications cabinets  202  may be insufficient to mount a fiber optic apparatus  200 . For example, the telecommunications cabinet  202  may not have sufficient internal volume to route cables or connect patch cords without risking damage, particularly when an access door is in a shut position. In some example embodiments, the fiber optic apparatus  200  may extend beyond a plane defined by an access opening of the telecommunications cabinet  202  when the fiber optic apparatus  200  is mounted in the telecommunications cabinet  202 , such as depicted in  FIG.  15   . 
     Turning to  FIGS.  12 A- 12 C , a retrofit door  1200  may be provided. The retrofit door may be configured to replace an access door  1302  of a telecommunications cabinet  202 , such as the Video Ready Access Device (VRAD) cabinet  1300  shown in  FIG.  13   . The retrofit door  1200  may be configured such that an internal volume of the telecommunications cabinet  202  is sufficient to enable mounting and connecting the fiber optic apparatus  200  when the retrofit door  1200  is installed on the telecommunications cabinet  202 , such as depicted in  FIG.  14   . 
     The retrofit door  1200  may include a front surface  1202 , a plurality of sidewalls  1204  extending from the front surface  1202  and a rear surface  1206 . The retrofit door  1200  may be formed from metal sheets, such as steel or aluminum. The retrofit door  1200  may be formed from a single metal sheet or a plurality of metal sheets. The metal sheet or sheets may be welded, riveted, or otherwise attached to itself or each other to form the retrofit door  1200 . In the depicted embodiment, the retrofit door  1200  includes four sidewalls  1204 , however additional sidewalls may be utilized based on the shape of the access opening of the telecommunications cabinet  202 , for example, five or six sidewalls, such as where the access opening has truncated the upper corner or corner. In some example embodiments one or more sidewalls  1204 , such as a top sidewall, may be curved or sloped downward to aid in water drainage and/or to limit or prevent snow or ice accumulation. 
     The rear surface  1206  may extend inward from the sidewalls  1204  and define an opening into a cavity of the retrofit door. The cavity of the retrofit door  1200  provides volume to accommodate the fiber optic apparatus, such as the fiber optic panels or the fiber optic equipment that is configured to be mounted to the f fiber optic panels. Additionally, the rear surface  1206  may be spaced apart from the front surface  1202 , such that that an internal volume of the telecommunications cabinet is sufficient to enable mounting and connecting the fiber optic apparatus  200  when the retrofit door  1200  is installed on the telecommunications cabinet  202 . For example, the front surface may be spaced from the rear surface by 2 inches, 4 inches, 5 inches, 6 inches or any other suitable distance. In an example embodiment, the rear surface  1206  may be disposed at a distal end of the sidewalls  1204 . Alternatively, the rear surface  1206  may be disposed at a medial position proximate to the distal end of the sidewalls  1204 , forming a lip around the rear surface  1206 . The rear surface  1206  may be configured to abut and/or partially compress a seal feature  1600  ( FIG.  16   ). Engagement or compression of the seal feature  1600  may provide a liquid and debris barrier or ingress protection (IP), such as IP  55 , IP  65 , or other suitable rating. 
     In some example embodiments, the retrofit door  1200  may include a handle  1208  configured to engage and disengage a latch feature  1210 . The handle  1208  may be configured to be operated by pulling, pushing, turning, or the like. The latch feature  1210  may include a cam and rod mechanism or other suitable latching feature to restrain the retrofit door  1200  in a shut position when the handle  1208  is in an engaged position and release the retrofit door  1200  when the handle  1208  is in a disengaged position. 
     The retrofit door  1200  may be connected to the telecommunications cabinet  202  by a hinge  1212 . The hinge  1212  may be disposed between a sidewall  1204  of the retrofit door  1200  and the access opening of the telecommunications cabinet  202 , such that the retrofit door  1200  may transition between the shut position and an open or access position. In some embodiments, the fiber optic apparatus  200  may be pivotably mounted in the telecommunications cabinet  202 , as described above in  FIGS.  8 A- 8 C . In some example embodiments the fiber optic apparatus  200  may be integrated into the hinge  1212 , such that the retrofit door  1200  and the fiber optic apparatus  200  share an axis of rotation. 
     The retrofit door  1200  may also include a wind latch  1214  configured to limit or prevent the retrofit door from swinging past a predetermined open angle. The wind latch  1214  may include a slot disposed parallel with an edge of a sidewall  1204 . The slot may be configured to receive a pin disposed at the end of a pivot bar attached to the telecommunications cabinet  202 . The pin of the pivot bar may slide along the slot of the wind latch  1214  when the retrofit door  1200  is transitioned between the open position and the shut position. Alternatively, the pivot bar may be attached to the retrofit door  1200  and the wind latch  1214  and associated slot may be disposed on the telecommunications cabinet  202 . 
     In an example embodiment, the telecommunications cabinet may include an ingress area  1700  for cable routing, as depicted in  FIG.  17   . The ingress area  1700  may be separate from the portion of the telecommunications cabinet  202  that houses the copper electronic equipment. The retrofit door  1200  may include a partition  1216  disposed between opposing sidewalls  1204  defining an upper portion and a lower portion of the retrofit door  1200 . The upper portion may be configured to seal the portion of the telecommunications cabinet  202  housing the copper electronic equipment as discussed above. The lower portion may be configured to cover the ingress area, sometimes referred to as an air chamber. In some example embodiments, the lower portion may have one or more vent apertures  1218  disposed through the front surface to enable air flow into and out of the ingress area, which may allow drainage or drying of the ingress area should water enter the ingress area.
