Abstract

An optical cable includes an optical component assembly, inner and outer optical fibers, a componentry cover, and a connector. The optical component assembly includes an optical unit. The inner and the outer optical fibers are on opposing sides of the optical unit such that the optical unit receives a first optical signal from the inner optical fiber and the outer optical fiber receives a second optical signal from the optical unit or such that the optical unit receives the second optical signal from the outer optical fiber and the inner optical fiber receives the first optical signal from the optical unit. The componentry cover encapsulates an entirety of the optical unit and portions of the inner and the outer optical fibers. The connector includes a portion of first outer optical fiber that is exposed to route the second optical signal.

First claim

an optical component assembly including an optical unit; first inner and first outer optical fibers on opposing sides of the optical unit such that the optical unit receives a first optical signal from the first inner optical fiber and the first outer optical fiber receives a second optical signal from the optical unit or such that the optical unit receives the second optical signal from the first outer optical fiber and the first inner optical fiber receives the first optical signal from the optical unit; a componentry cover encapsulating an entirety of the optical unit and first portions of the first inner and the first outer optical fibers; and a connector including a second portion of the first outer optical fiber, the second portion being exposed to route the second optical signal.

2 . The cable of claim 1 , wherein the optical unit is a termination unit and each of the inner and outer optical fibers terminates at the termination unit.

3 . The cable of claim 1 , wherein the optical unit is at least one selected from the group of a termination unit, wavelength-division multiplexer (WDM), a tap filter, a reflector, an attenuator, and a dispersion compensator.

4 . The cable of claim 1 , wherein the connector further includes a ferrule and the second portion of the first outer optical fiber extends through the ferrule.

5 . The cable of claim 4 , wherein the connector further includes a connector housing surrounding a portion of the ferrule.

6 . The cable of claim 1 , further comprising:
a jacket surrounding a second portion of the first inner optical fiber; and a chamfer or round having opposing ends attached to the componentry cover and the jacket, respectively.

7 . The cable of claim 6 , wherein an outside diameter of the componentry cover is larger than an outside diameter of the jacket such that the respective chamfer or round tapers from the componentry cover to the jacket.

8 . The cable of claim 6 , wherein the respective chamfer or round is a boot overlying the jacket and being adjacent to the componentry cover to expose the componentry cover.

9 . The cable of claim 1 , further comprising an additional inner optical fiber and an additional outer optical fiber, the additional inner and the additional outer optical fibers being on opposing sides of the optical unit such that the optical unit receives a third optical signal from the additional inner optical fiber and the additional outer optical fiber receives a fourth optical signal from the optical unit or such that the optical unit receives the fourth optical signal from the additional outer optical fiber and the additional inner optical fiber receives the third optical signal from the optical unit,
wherein the componentry cover further encapsulates respective first portions of the additional inner and the additional outer optical fibers, and wherein the connector includes a respective second portion of the additional outer optical fiber, the second portion of the additional outer optical fibers being exposed to route the fourth optical signal.

10 . The cable of claim 9 , wherein the connector further includes a ferrule and the second portions of the first outer optical fiber and the additional outer optical fiber extend through the ferrule.

11 . The cable of claim 10 , wherein the connector further includes a connector housing surrounding a portion of the ferrule.

12 . The cable of claim 9 , wherein the connector further includes a connector housing and the second portions of the first outer optical fiber and the additional outer optical fiber extend through the connector housing, the connector housing being non-cylindrical.

13 . The cable of claim 12 , wherein the connector further includes a pair of ferrules, the connector housing surrounding portions of the pair of the ferrules, wherein the second portion of the first outer optical fiber extends through one of the pair of the ferrules, and wherein the second portion of the additional outer optical fiber extends through the other one of the pair of the ferrules.

14 . The cable of claim 1 , further comprising a bendable cover attaching the componentry cover to the connector, wherein the bendable cover is bendable from a first state to a second state, and wherein the second state is maintained in the absence of an external force being applied to the optical cable.

15 . The cable of claim 14 , wherein the bendable cover is bendable to at most an angle corresponding to a minimum bending radius for the optical fibers.

16 . The cable of claim 14 , wherein the bendable cover and the componentry cover are integral with each other such that the covers are inseparable without fracture of at least one of the covers.

17 . The cable of claim 14 , wherein the bendable cover is in the form of bellows.

18 . The cable of claim 14 , further comprising a boot overlying the jacket and the componentry cover, the boot being adjacent to the respective bendable cover to expose the bendable cover.

19 . The cable of claim 1 , further comprising a hinge including a pin attaching the componentry cover to the connector.

20 . The cable of claim 1 , wherein the componentry cover or the connector includes a protrusion and the other of the componentry cover or the connector includes a hole receiving the protrusion to attach the componentry cover to the connector.

21 . The cable of claim 1 , further comprising a ball-and-socket joint including a ball attached to the componentry cover or the connector and a socket attached to the other of the componentry cover and the connector.

22 . The cable of claim 21 , wherein the ball includes a ball passageway and the socket includes a socket passageway such that the second portion of the first optical fiber extends through at least one of the ball passageway or the socket passageway.

23 . The cable of claim 1 , wherein the componentry cover defines a notch extending to an end of the cover through which the first inner optical fiber extends.

24 . An optical cable combination, comprising:
the cable of claim 23 , such cable being a first cable; and an additional cable in the form of the first cable, wherein the additional cable is bendable such that a portion of a componentry cover of the additional cable is able to contact the notch of the first cable when the additional cable and first cable are in respective bent states.

25 . An optical cable combination, comprising:
the cable of claim 23 , such cable being a first cable; and an additional cable in the form of the first cable, wherein the additional cable is bendable such that a portion of a componentry cover of the additional cable fits within the notch of the first cable when the additional cable and first cable are in respective bent states.
