Abstract

An interface provides protection and support for transitioning a jacketed fiber optic cable. The interface has a crimp body, a transition portion and a front end to receive an adapter. The interface preferably has a main body with two pieces that are identical. The two pieces have tabs and recesses corresponding to the tabs for alignment and structure. The main body also may have an opening for an adapter latch. A crimp band fits over the crimp body to secure the jacketed fiber optic cable to the interface.

First claim

We claim:

1. An optical interconnect assembly for connecting optical fibers in an individual jacketed cable from a bigger optical cable bundle to at least two duplex fiber optic connectors at an adapter, the optical interconnect assembly comprising:
at least two duplex fiber optic connectors, each of the at least two duplex fiber optic connectors having a height greater than a width;
an adapter having a first opening and a second opening, wherein the first opening is configured to receive the at least two duplex fiber optic connectors in a side-by-side arrangement along a width of the adapter; and
an interface having a front end mateable to the adapter at the second opening via at least one latch opening configured to receive at least one latch of the adapter and a back end configured to receive the individual jacketed fiber optic cable from the bigger optical cable bundle,
wherein the interface has an interior opening extending between the front end and the back end, the interior opening transitions from a narrower opening to a broader opening between the front end and the back end to strain-relieve optical fibers of the individual jacketed cable, the optical fibers being terminated at respective at least two additional duplex fiber optic connectors enclosed by the interface and mated with the at least two duplex fiber optic connectors inside the adapter, the at least two additional duplex fiber-optic connectors are received at the second opening of the adapter.

2. The optical interconnect assembly of claim 1 , wherein the at least two small form factor fiber optic connectors are smaller than the at least two duplex fiber optic connectors.

3. The optical interconnect assembly of claim 1 , wherein the at least two duplex fiber-optic connectors include at least four duplex fiber optic connectors and the at least two small form factor duplex fiber optic connectors include at least four small form factor duplex fiber optic connectors.

4. The optical interconnect assembly of claim 1 , wherein the back end of the interface is connected to the individual jacketed fiber optic cable with a crimp band over a crimp body disposed at the back end.

5. The optical interconnect assembly of claim 4 , wherein the interface further comprises a boot at least partially covering the crimp body and providing additional support to the individual jacketed fiber optic cable adjacent the back end of the main body.

6. The optical interconnect assembly of claim 1 , wherein an exterior of the interface also transitions from a narrower portion at the back end to a wider portion at the front end.

7. The optical interconnect assembly of claim 1 , wherein each of the at least two duplex fiber optic connectors is an MDC connector.

8. The optical interconnect assembly of claim 1 , wherein the main body of the interface further comprises a first piece and a second piece, the first piece and the second piece mateable to one another.

9. The optical interconnect assembly of claim 8 , wherein the first piece and the second piece are mateable to one another in a clam shell arrangement.

10. An optical interconnect assembly for connecting optical fibers in an individual jacketed fiber optic cable from a bigger optical cable bundle to at least two small form factor MDC fiber optic connectors at an adapter, the optical interconnect assembly comprising:
at least two small form factor MDC fiber optic connectors;
an adapter having a first opening and a second opening, wherein the first opening is configured to receive the at least two small form factor MDC fiber optic connectors; and
an interface having a front end mateable to the adapter at the second opening via at least one latch opening configured to receive at least one latch of the adapter and a back end configured to receive the individual jacketed fiber optic cable from the bigger optical cable bundle,
wherein the interface has an interior opening extending between the front end and the back end, the interior opening transitions from a narrower opening to a broader opening between the front end and the back end to strain-relieve optical fibers of the individual jacketed fiber optic cable, the optical fibers being mated with the at least two small form factor MDC fiber optic connectors inside the adapter.

11. The optical interconnect assembly according to claim 10 , wherein the main body of the interface is connected to the jacketed fiber optic cable with a crimp band over the crimp body.

12. The optical interconnect assembly according to claim 11 , wherein the interface further comprises a boot at least partially covering the crimp body and providing additional support to the jacketed fiber optic cable adjacent the back end of the main body.

13. The optical interconnect assembly according to claim 10 , wherein the main body of the interface further comprises a first piece and a second piece, the first piece and the second piece mateable to one another.

14. The optical interconnect assembly according to claim 13 , wherein the main body of the interface further comprises a first latch mechanism and a second latch mechanism on each of the first and second pieces, wherein the first latch mechanism faces away from the internal opening and second latch mechanism faces toward the internal opening.

15. The optical interconnect assembly according to claim 13 , wherein the first piece and the second piece are identical to one another.

16. The optical interconnect assembly according to claim 13 , wherein the first piece has a first tab recess and a first tab and the second piece has a second tab recess and a second tab, wherein the second tab is aligned with the first tab recess and the first tab is aligned with the second tab recess.

17. An optical interconnect assembly for connecting optical fibers in an individual jacketed cable from a bigger optical cable bundle to at least two multi-fiber fiber optic connectors at an adapter, the optical interconnect assembly comprising:
at least two multi-fiber fiber optic connectors, each of the at least two multi-fiber fiber optic connectors having a height greater than a width;
an adapter having a first opening and a second opening, wherein the first opening is configured to receive the at least two multi-fiber fiber optic connectors in a side-by-side arrangement along a width of the adapter; and
an interface having a front end mateable to the adapter at the second opening via at least one latch opening configured to receive at least one latch of the adapter and a back end configured to receive the individual jacketed fiber optic cable from the bigger optical cable bundle,
wherein the interface has an interior opening extending between the front end and the back end, the interior opening transitions from a narrower opening to a broader opening between the front end and the back end to strain-relieve optical fibers of the individual jacketed cable, the optical fibers being terminated at respective at least two additional-multi-fiber fiber optic connectors enclosed by the interface and mated with the at least two multi-fiber fiber optic connectors inside the adapter, the at least two additional multi-fiber fiber optic connectors are received at the second opening of the adapter.

18. The optical interconnect assembly of claim 17 , wherein an exterior of the interface also transitions from a narrower portion at the back end to a wider portion at the front end.

19. The optical interconnect assembly of claim 17 , wherein the back end of the interface is connected to the individual jacketed fiber optic c
