Abstract

An optical connector assembly 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

The invention claimed is:

1. An optical connector assembly comprising:
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;
a connector through which a second portion of the first outer optical fiber extends, the second portion being exposed to route the second optical signal; and
a bendable cover attaching the componentry cover to the connector,
wherein the bendable cover has an outer diameter along an entirety of a length of the bendable cover at least as large as an outer diameter of the componentry cover where the bendable cover attaches to the componentry cover.

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

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

6. The connector assembly 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 connector assembly 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 connector assembly of claim 6 , further comprising a boot overlying the jacket and adjacent to the componentry cover to expose the componentry cover, wherein the respective chamfer or round is defined by the boot.

9. The connector assembly of claim 1 , 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 connector assembly.

10. The connector assembly of claim 9 , wherein the bendable cover is bendable to at most an angle corresponding to a minimum bending radius for the optical fibers.

11. The connector assembly of claim 9 , wherein the bendable cover and the componentry cover are integral with each other such that the covers are inseparable without fracture of either one or both of the covers.

12. The connector assembly of claim 9 , wherein the bendable cover is in the form of bellows.

13. The connector assembly 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.

14. The connector assembly of claim 1 , wherein the outer diameter of the bendable cover is at least as large as an outer diameter of the componentry cover along an entirety of a length of the componentry cover.

15. The connector assembly of claim 14 , wherein the optical unit includes an electro-optical component configured for attachment to an electrical wire to thereby convey an electrical signal from the electrical wire.

16. An optical cable termination assembly, comprising:
the connector assembly of claim 1 ; and
a termination unit, the connector assembly being inserted into the termination unit to either one or both of i) route the second optical signal from the first outer optical fiber to another optical connector assembly inserted in the termination unit and ii) receive the second optical signal at the first outer optical fiber from the other optical connector assembly inserted in the termination unit.

17. An optical connector assembly combination, comprising:
the connector assembly of claim 13 , such connector assembly being a first connector assembly; and
an additional connector assembly in the form of the first connector assembly, wherein the additional connector assembly is bendable such that a portion of a componentry cover of the additional connector assembly is able to contact the notch of the first connector assembly when the additional connector assembly and the first connector assembly are in respective bent states.

18. An optical connector assembly combination, comprising:
the connector assembly of claim 13 , such connector assembly being a first connector assembly; and
an additional connector assembly in the form of the first connector assembly, wherein the additional connector assembly is bendable such that a portion of a componentry cover of the additional connector assembly fits within the notch of the first connector assembly when the additional connector assembly and the first connector assembly are in respective bent states.

19. An optical connector assembly comprising:
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;
a connector through which a second portion of the first outer optical fiber extends, the second portion being exposed to route the second optical signal; and
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 the second state is maintained in the absence of an external force being applied to the optical connector assembly,
wherein less force is required to bend the bendable cover than to bend the componentry cover, and
wherein the second portion of the first outer optical fiber further extends through the bendable cover.

20. The connector assembly of claim 19 , wherein the bendable cover is configured to be straight in either the first state or the second state.
