Abstract

An indoor fiber optic cable assembly comprising a flame retardant fiber optic distribution cable comprising at least one network access point at which at least one optical fiber is preterminated, a flame retardant flexible closure substantially enclosing the at least one network access point, and at least one tether secured about the flexible closure and comprising at least one optical fiber within that is optically connected with the at least one preterminated optical fiber of the distribution cable. The flexible closure may be overmolded or a heat shrink and the cable and closure are riser, plenum or low smoke zero halogen rated, among others. Tethers may be splice ready, connectorized or terminate in a multi-port connection terminal.

Claims

1. An indoor fiber optic cable assembly, comprising:

a flame retardant fiber optic distribution cable comprising at least one network access point at which at least one optical fiber is preterminated;

a flame retardant flexible closure substantially enclosing the at least one network access point; and

at least one tether secured about the flexible closure and comprising at least one optical fiber within that is optically connected with the at least one preterminated optical fiber of the distribution cable.

2. The indoor fiber optic cable assembly of claim 1, wherein the flexible closure is an overmold.

3. The indoor fiber optic cable assembly of claim 1, wherein the flexible closure is a heatshrink.

4. The indoor fiber optic cable assembly of claim 1, wherein the fiber optic distribution cable and the flexible closure are riser, plenum or low smoke zero halogen rated.

5. The indoor fiber optic cable assembly of claim 1, wherein the cable assembly includes a microstructured optical fiber.

6. The indoor fiber optic cable assembly of claim 1, wherein the distribution cable and the flexible closure are flame retarded using materials selected from the group consisting of fillers, tapes, spray on or paintable coatings, woven or composite glass polymer mantles, additives, brominated additives, inert mineral fillers, hydrated mineral fillers, mixtures of alkaline salts and polyphosphate compounds, flame inhibiting silicone processing and hydrated mixed-metal carbonates.

7. The indoor fiber optic cable assembly of claim 1, wherein the at least one tether is connectorized.

8. The indoor fiber optic cable assembly of claim 1, wherein the at least one tether is optically connected to a multi-port connection terminal.

9. The indoor fiber optic cable assembly of claim 1, wherein the cable assembly is deployed in a multi-dwelling unit.

10. An indoor fiber optic cable assembly, comprising:

a flame retardant fiber optic distribution cable comprising at least one network access point at which at least one optical fiber is preterminated;

a flexible closure covered with a flame-retarding barrier material so as to make the flexible closure flame retardant, the flexible closure substantially enclosing the at least one network access point; and

at least one tether secured about the flexible closure and comprising at least one optical fiber within that is optically connected with the at least one preterminated optical fiber of the distribution cable.

11. The indoor fiber optic cable assembly of claim 10, wherein the flexible closure is an overmold.

12. The indoor fiber optic cable assembly of claim 10, wherein the flexible closure is a heatshrink.

13. The indoor fiber optic cable assembly of claim 10, wherein the fiber optic distribution cable is riser, plenum or low smoke zero halogen rated.

14. The indoor fiber optic cable assembly of claim 10, wherein the cable assembly includes a microstructured optical fiber.

15. The indoor fiber optic cable assembly of claim 10, wherein the distribution cable is flame retarded using materials selected from the group consisting of fillers, tapes, spray on or paintable coatings, woven or composite glass polymer mantles, additives, brominated additives, inert mineral fillers, hydrated mineral fillers, mixtures of alkaline salts and polyphosphate compounds, flame inhibiting silicone processing and hydrated mixed-metal carbonates.

16. The indoor fiber optic cable assembly of claim 10, wherein the at least one tether is connectorized.

17. The indoor fiber optic cable assembly of claim 10, wherein the at least one tether is optically connected to a multi-port connection terminal.

18. The indoor fiber optic cable assembly of claim 10, wherein the cable assembly is deployed in a multi-dwelling unit.

19-20. -20. (canceled)

21. A method of flame retarding a flexible network access point closure having an outside portion, comprising applying a flame retardant barrier material to the outside portion of the closure.

23. The method according to claim 21, wherein the flexible closure is an overmold.

24. The method according to claim 21, wherein the flexible closure is a heat shrink.

22. (canceled)
