Abstract

The present disclosure includes systems and apparatuses for an optical fiber management system. One embodiment of an optical fiber management system includes a cabinet comprising a system of building blocks that make up a rail-mounting system and an optical fiber management apparatus housed within one of the building blocks. The optical fiber management apparatus can comprise a housing, an adaptor plate resiliently connected to the housing, a splice tray, a housing cover, a radius limiter, and a base configured for integrated slack storage of at least one of buffer tube and ribbon cable.

Claims (56)

1. An optical fiber management system comprising:

one or more L-shaped building blocks comprising:

a side portion having a rail-mounting system; and

a back portion having at least one top fastening component and at least one bottom fastening component, the at least one bottom fastening component complementary to the at least one top fastening component;

wherein the at least one top and bottom fastening component enable two or more L-shaped building blocks to be vertically coupled together;

the one or more L-shaped building blocks configured to receive an optical fiber management apparatus comprising:

a housing;

an adaptor plate; and

a radius limiter.

2. The optical fiber management system of claim 1 , wherein the one or more L-shaped blocks are housed in a front-access-only cabinet; and

wherein an interior of the cabinet is not configured for slack storage.

3. The optical fiber management system of claim 1 , further comprising a radius-limiting rod protruding from a front of the side portion of the one or more building blocks and configured to provide bend radius protection.

4. The optical fiber management system of claim 1 , wherein the rail-mounting system comprises a first rail accommodating a first optical fiber management apparatus and a second rail accommodating a second optical fiber management apparatus.

5. The optical fiber management system of claim 1 , wherein the radius limiter comprises a first portion located on the base of the optical fiber management apparatus and a second portion configured to mate with the first portion and located on a base cover of the optical fiber management apparatus.

6. An optical fiber management system comprising:

a system of removable building blocks that vertically interlock with each other and each are formed by lockable portions and extend horizontally as an L-shape, the system comprising a rail-mounting system and a radius limiting rod;

one or more optical fiber management apparatuses resiliently mounted within the rail-mounting system, wherein each optical fiber management apparatus comprise:

a housing;

an adaptor plate;

a housing cover;

a base comprising at least a first portion of a radius limiter; and

at least one of:

integrated slack storage of buffer tube; and

integrated slack storage of ribbon cable,

wherein the rail-mounting system of each building block accommodates at least two vertically stacked optical fiber management apparatuses; and

wherein each building block comprises no more than one radius-limiting rod protruding from a front of the building block and configured to provide bend radius protection.

7. The optical fiber management system of claim 6 , wherein the adaptor plate is resiliently connected to the housing.

8. The optical fiber management system of claim 6 , wherein at least one of the one or more optical fiber management apparatuses is preloaded with at least one of a slack storage buffer tube and a slack storage ribbon cable.

9. The optical fiber management system of claim 6 , wherein each of the one or more optical fiber management apparatuses further comprises:

a splice tray; and

resiliently-connected connector tabs.

10. The optical fiber management system of claim 9 , wherein each of the one or more optical fiber management apparatuses further comprises a splice tray cover distinct from the housing cover.

11. The optical fiber management system of claim 9 , wherein:

the housing comprises a surface that provides a first level of individual fiber management and at least one opening that allows entry of an optical fiber cable into the housing;

the adaptor plate is resiliently connected to the housing and comprises a plurality of optical fiber connectors, the adaptor plate being releasable from the housing and providing access to both sides of the adaptor plate;

the splice tray comprises a plurality of splice channels and a surface that provides a second level of individual fiber management spaced from the first level of individual fiber management; and

the housing cover is resiliently connected to the housing, the housing cover being removable from the housing to allow access to the splice tray therebeneath.

12. The optical fiber management system of claim 9 , wherein the splice tray is nested atop the base.

13. The optical fiber management system of claim 6 , wherein the building blocks are housed in a cabinet not configured for slack storage of buffer or ribbon cable.

14. The optical fiber management system of claim 6 , wherein the one or more optical fiber management apparatuses comprise two optical fiber management apparatuses.

15. The optical fiber management system of claim 6 , wherein each of the one or more optical fiber management apparatuses further comprises a base cover resiliently connected to the base and comprising a second portion of the radius limiter.

16. The optical fiber management system of claim 6 , wherein the building blocks are housed in a cabinet comprising a rail system of interlocking building blocks, wherein:

the building blocks interlock via sliding into one another; and

the building blocks comprise rails to receive a number of optical fiber management apparatuses.

17. The optical fiber management system of claim 6 , further comprising a jumper route path in a central position of an interior of the cabinet and columns of the one or more of optical fiber management apparatuses on outer portions of the interior of the cabinet, wherein the jumper route path comprises a W intra-bay route path.

18. An optical fiber management system comprising:

a system of removable L-shaped building blocks that vertically interlock with each other comprising: a first lockable component mated with a second lockable component in the form of the L-shaped building blocks, the first lockable component comprising a rail-mounting system; and

the rail-mounting system configured to receive up to two optical fiber management apparatuses comprising an optical fiber management cassette, the cassette comprising:

a housing comprising a surface that provides a first level of individual fiber management and at least one opening that allows entry of an optical fiber cable into the housing;

an adaptor plate comprising a plurality of optical fiber connectors, the adaptor plate being releasable from the housing and providing access to both sides of the adaptor plate;

a base comprising integrated jacketed fiber storage and a first portion of a radius limiter;

a base cover comprising a second portion of the radius limiter configured to mate with the first portion of the radius limiter;

outside ridges configured to slide along a rail of the rail-mounting system of one of the L-shaped building blocks; and

a splice tray comprising a plurality of splice channels, at least one fiber nest that provides storage of coiled individual optical fiber, and a surface that provides a second level of individual fiber management spaced from the first level of fiber management.

19. The optical fiber management system of claim 18 , further comprising a housing cover resiliently connected to the housing, wherein when the adaptor plate is exercised from a front of the cassette, both sides of the adaptor plate are accessible without removing the housing cover, and the housing cover is removable from the housing to allow access to the splice tray therebeneath.

20. The optical fiber management system of claim 18 , wherein the integrated jacketed fiber storage comprises continuous storage of buffer tube storage, 900 micron fiber storage, and 250 micron fiber storage.
