Abstract

An adapter assembly includes a single-piece or two-piece multi-fiber adapter defining a recess at which a contact assembly is disposed. The adapter assemblies can be disposed within adapter block assemblies or cassettes, which can be mounted to moveable trays. Both ports of the adapters disposed within adapter block assemblies are accessible. Only one port of each adapter disposed within the cassettes are accessible. Circuit boards can be mounted within the block assemblies or cassettes to provide communication between the contact assemblies and a data network.

Claims (23)

1. A fiber optic cassette arrangement comprising:

a body extending along a depth between a front and a rear, extending along a width between opposite first and second sides, and extending along a height between a bottom and an open top, the body defining a retention arrangement at the first side of the body, the bottom of the body defining an external channel extending along the depth of the body, the body defining a first rear port opening disposed at the rear of the body between the bottom channel and the first side of the body and a second rear port opening disposed at the rear of the body between the bottom channel and the second side of the body, and the body defining a plurality of front port openings at the front of the body;

a multi-fiber optical adapter disposed at the first rear port opening; and

a plurality of front optical adapters disposed at the front port openings.

2. The fiber optic cassette arrangement of claim 1 , wherein the multi-fiber optical adapter is a first multi-fiber optical adapter; and wherein the fiber optic cassette arrangement further comprises a second multi-fiber optical adapter disposed at the second rear port opening.

3. The fiber optic cassette arrangement of claim 1 , wherein the retention arrangement is configured to secure the fiber optic cassette arrangement to a tray.

4. The fiber optic cassette arrangement of claim 1 , wherein the retention arrangement is a first retention arrangement; and wherein a second retention arrangement is disposed at the second side of the body.

5. The fiber optic cassette arrangement of claim 1 , wherein the multi-fiber optical adapter is offset along the width of the body from the front optical adapters.

6. The fiber optic cassette arrangement of claim 1 , wherein a cover is mounted to the body to close the open top and define an interior.

7. The fiber optic cassette arrangement of claim 6 , further comprising optical fibers extending between the multi-fiber optical adapter and a first of the front optical adapters.

8. The fiber optic cassette arrangement of claim 7 , further comprising a cable routing arrangement disposed within the interior at a fiber management region of the body, wherein the optical fibers wind around the cable routing arrangement.

9. The fiber optic cassette arrangement of claim 8 , wherein the cable routing arrangement includes a spool.

10. The fiber optic cassette arrangement of claim 8 , wherein a portion of the fiber management region of the body is thinner than a connection region of the body, wherein the front optical adapters are disposed at the connection region.

11. The fiber optic cassette arrangement of claim 1 , wherein the front optical adapters are separated into a plurality of groups, wherein the groups are spaced apart from each other more than the front optical adapters within each group are spaced.

12. The fiber optic cassette arrangement of claim 1 , further comprising a circuit board carried by the body.

13. The fiber optic cassette arrangement of claim 12 , wherein the multi-fiber optical adapter is mounted to the circuit board.

14. The fiber optic cassette arrangement of claim 12 , wherein the bottom of the body defines an opening in alignment with the circuit board.

15. The fiber optic cassette arrangement of claim 14 , further comprising a shroud extending downwardly from the opening.

16. The fiber optic cassette arrangement of claim 14 , wherein the opening is one of a plurality of openings through the bottom of the body in alignment with the circuit board.

17. The fiber optic cassette arrangement of claim 14 , wherein the opening is spaced from the front optical adapters.

18. The fiber optic cassette arrangement of claim 14 , wherein the opening is spaced from the multi-fiber optical adapter.

19. The fiber optic cassette arrangement of claim 14 , wherein the circuit board is a first circuit board; and wherein the fiber optic cassette arrangement comprises a tray on which the fiber optic cassette is mounted, the tray carrying a second circuit board.

20. The fiber optic cassette arrangement of claim 19 , further comprising electrical contacts extending through the opening between the first and second circuit boards.
