Abstract

An optical connection terminal assembly for a fiber optic communications network includes an optical connection terminal. The terminal includes a base, the base including an exterior wall, and a cover connected to the base wherein an interior cavity is defined between the base and the cover. The terminal further includes an all-dielectric self-supporting (“ADSS”) cable port defined in the cover, and a plurality of connector ports defined in the exterior wall of the base. The terminal assembly further includes an ADSS cable connector including a main body and a connector body, the ADSS cable connector positionable such that the connector body extends through the ADSS cable port into the interior cavity. The terminal assembly further includes an ADSS cable connected to the cable connector, wherein optical fibers of the ADSS cable extend through the ADSS cable connector and through the ADSS cable port into the interior cavity.

First claim

What is claimed is:

1. An optical connection terminal assembly for a fiber optic communications network, the terminal assembly comprising:
an optical connection terminal, the optical connection terminal comprising:
a base, the base comprising an exterior wall;
a cover connected to the base wherein an interior cavity is defined between the base and the cover;
an all-dielectric self-supporting (“ADSS”) cable port defined in the cover; and
a plurality of connector ports defined in the exterior wall of the base;

an ADSS cable connector, the ADSS cable connector comprising a main body and a connector body, wherein a longitudinal axis of the connector body is perpendicular to a longitudinal axis of the main body, the ADSS cable connector positionable such that the connector body extends through the ADSS cable port into the interior cavity; and
an ADSS cable connected to the cable connector, wherein optical fibers of the ADSS cable extend through the ADSS cable connector and through the ADSS cable port into the interior cavity.

2. The optical connection terminal assembly of claim 1 , wherein the cover comprises a bottom panel, a first end wall, a second opposing end wall, a first sidewall, and a second opposing sidewall, wherein the bottom panel extends between the first end wall and opposing second end wall and between the first side wall and second opposing sidewall, wherein an exterior channel is defined in the bottom panel, and wherein the ADSS cable port is defined in the bottom panel within the exterior channel of the cover.

3. The optical connection terminal assembly of claim 2 , wherein the ADSS cable connector is positionable such that the main body is within the exterior channel and the connector body extends through the ADSS cable port into the interior cavity.

4. The optical connection terminal assembly of claim 1 , wherein the connector body is threaded.

5. The optical connection terminal assembly of claim 1 , wherein the main body defines an interior channel and a furcation block is disposed within the interior channel, and wherein the optical fibers extend through the furcation block.

6. The optical connection terminal assembly of claim 1 , wherein the main body defines an interior channel and a retainer extending into the interior channel, the retainer contacting an outer jacket of the ADSS cable.

7. The optical connection terminal assembly of claim 6 , wherein the retainer is a sawtooth sidewall.

8. The optical connection terminal assembly of claim 1 , wherein the main body defines an interior channel and opposing protrusions extending into the interior channel, the opposing protrusions dividing the interior channel into a first portion and a second portion, wherein strength fibers and a strength member of the ADSS cable terminate in the first portion and buffer tubes of the ADSS cable terminate in the second portion.

9. The optical connection terminal assembly of claim 1 , wherein the main body defines an interior channel and a stop extends into the interior channel, and wherein an outer jacket of the ADSS cable contacts and terminates at the stop.

10. The optical connection terminal assembly of claim 1 , wherein the main body defines an interior channel and a pocket.

11. The optical connection terminal assembly of claim 1 , wherein an adhesive is disposed within the main body and the connector body, the adhesive contacting the ADSS cable.

12. The optical connection terminal assembly of claim 11 , wherein the adhesive has a viscosity of between 400 and 900 cP at 25° C.

13. The optical connection terminal assembly of claim 1 , wherein the ADSS cable connector further comprises a cover panel, the cover panel connected to the main body.

14. The optical connection terminal assembly of claim 13 , wherein a pocket is defined in the cover panel.

15. The optical connection terminal of claim 1 , wherein the ADSS cable connector further comprises a boot, the boot connected to the main body.

16. The optical connection terminal of claim 15 , wherein the ADSS cable connector further comprises a clamp ring disposed between the boot and the main body.

17. An optical connector assembly for an optical connection terminal, the optical connector assembly comprising:
an all-dielectric self-supporting (“ADSS”) cable connector, the ADSS cable connector comprising a main body and a connector body, wherein a longitudinal axis of the connector body is perpendicular to a longitudinal axis of the main body, the ADSS cable connector further comprising a cover panel connected to the main body, the main body defining an interior channel; and
an ADSS cable connected to the cable connector, wherein optical fibers of the ADSS cable extend through the main body and the connector body and exit the ADSS cable connector through the connector body.

18. The optical connector assembly of claim 17 , wherein the ADSS cable comprises an outer jacket, a fiber-reinforced polymer strength member and a plurality of buffer tubes disposed within the outer jacket, and a plurality of optical fibers disposed in at least one of the plurality of buffer tubes.

19. The optical connector assembly of claim 17 , wherein a furcation block is disposed within the interior channel, and wherein the optical fibers extend through the furcation block.

20. The optical connector assembly of claim 17 , wherein a retainer extending into the interior channel, the retainer contacting an outer jacket of the ADSS cable.

21. The optical connector assembly of claim 20 , wherein the retainer is a sawtooth sidewall.

22. The optical connector assembly of claim 17 , wherein opposing protrusions extending into the interior channel, the opposing protrusions dividing the interior channel into a first portion and a second portion, wherein strength fibers and a strength member of the ADSS cable terminate in the first portion and buffer tubes of the ADSS cable terminate in the second portion.

23. The optical connector assembly of claim 17 , wherein a stop extends into the interior channel, and wherein an outer jacket of the ADSS cable contacts and terminates at the stop.
