Abstract

A closure (100) facilitates upgrading a network to extend optical fibers closer to, or all the way to, the subscribers by facilitating the transition between optical signals to electrical signals. The closure includes a base (110) and a cover (120) defining an interior; and a circuit board (130) disposed within the interior. A management tray (140) can be coupled to the base. The circuit board (130) includes the optoelectronic circuitry. The management tray (140) includes a platform (141) disposed between the circuit board (130) and the cover (120). Various types of fiber and electrical cable sub-assemblies (160) can be received at a port (113) defined in the closure.

Claims

1. A closure for optoelectronic circuitry comprising:

a base having a sidewall extending upwardly from a bottom, the sidewall defining a cable port;

cooling pads disposed at the bottom of the base;

a cover that attaches to the base to close an interior of the closure;

a circuit board disposed within the interior of the closure, the circuit board including the optoelectronic circuitry; and

a management tray coupled to the base, the management tray including a platform disposed between the circuit board and the cover, the management tray including a fiber coupling region and a fiber storage region.

2. The closure of claim 1, further comprising a cable sub-assembly configured to be sealingly coupled to the closure at the cable port, the cable sub-assembly including an optical fiber cable and an electrical cable.

3. The closure of claim 2, wherein the cable sub-assembly includes a plurality of electrical cables.

4. The closure of claim 2, wherein the cable sub-assembly includes:

an optical fiber cable including an optical fiber within a jacket, the optical fiber cable extending between a first end and a second end;

a plurality of electrical cables including twisted pair conductors within jackets, the electrical cables extending between first and second ends; and

a sealing arrangement disposed at an intermediate location along the cables, the sealing arrangement including a body and a gasket that seals between the jackets of the cables and the body, the sealing arrangement also being configured to seal to a closure at a port defined by the closure, the sealing arrangement also being configured to seal an interior of at least one of the cables.

5. The closure of claim 4, wherein the body of the sealing arrangement includes a first clamping member and a second clamping member between which the gasket is disposed.

6. The closure of claim 5, wherein the second clamping member carries an external O-ring.

7. The closure of claim 5, wherein the first and second clamping members are fastened together.

8. The closure of claim 5, wherein the sealing arrangement also includes a boot that provides bend control for the cables.

9. The closure of claim 1, further comprising cooling structures disposed on at least one of the base and the cover.

10. The closure of claim 9, wherein the cooling structures are disposed on both the base and the cover.

11. The closure of claim 9, wherein the cooling structures include elongated fins.

12. The closure of claim 9, wherein the cooling structures include raised square structures.

13. The closure of claim 9, wherein the cooling structures include raised pyramids.
