Abstract

A splice cassette ( 100 ) includes a housing ( 114 ) which defines a first and a second interiors ( 132,134 ) facing in opposite directions. A first splice region ( 150 ) is disposed in the first interior ( 132 ) and a second splice region ( 152 ) is disposed in the second interior ( 134 ). A splice holder ( 180,185 ) can be mounted removably at one or more of the splice regions ( 150,152 ).

Claims (45)

1 . A splice cassette comprising:

a housing extending along a length between a front and a rear, extending along a width between opposite first and second sides, and extending along a height between opposite first and second ends, the housing defining a first interior open at the first end of the housing and a second interior open at the second end of the housing, each of the first and second interiors extending along at least a majority of the length and along at least a majority of the width;

a first splice region disposed in the first interior and facing towards the first end of the housing;

a second splice region disposed in the second interior and facing towards the second end of the housing;

a cable anchor region disposed at the rear of the housing, wherein the cable anchor region includes a first anchor position and a second anchor position, the first anchor position leading to the first interior, and the second anchor position leading to the second interior; and

a termination region disposed at the front of the housing, the termination region including a first row of adapters and a second row of adapters;

wherein each of the first and second interiors of the housing extends between a respective one of the first and second ancho positions and a respective one of the first and second rows of adapters.

2 . The splice cassette of claim 1 , further comprising a pass-through aperture extending between the first and second interiors.

3 . The splice cassette of claim 1 , further comprising a first pass-through aperture disposed at the first anchor position and a second pass-through aperture disposed at the second anchor position, the first pass-through aperture providing selective routing to both of the first and second interiors from the first anchor position.

4 . The splice cassette of claim 1 , wherein the first splice region is offset toward the first side and the second splice region is offset toward the second side.

5 . The splice cassette of claim 1 , further comprising a splice chip disposed at the first splice region, the splice chip configured to receive a plurality of single-fiber splices.

6 . The splice cassette of claim 5 , wherein a release arrangement for the splice chip is accessible from the second interior.

7 . The splice cassette of claim 1 , further comprising a splice holder disposed at the first splice region, the splice holder configured to receive a multi-fiber splice.

8 . The splice cassette of claim 1 , further comprising a plurality of fiber pigtails extending between first and second ends, the first ends being disposed at the first splice region, the second ends being terminated at plug connectors.

9 . The splice cassette of claim 1 , further comprising a fiber cable including a plurality of optical fibers each having a first end terminated at a respective plug connector.

10 . The splice cassette of claim 9 , further comprising a termination bezel disposed at the front of the housing, the termination bezel defining a plurality of inner ports configured to receive the plug connectors.

11 . The splice cassette of claim 10 , wherein the termination bezel holds the first and second rows of adapters defining the inner ports.

12 . The splice cassette of claim 1 , further comprising a blank bezel disposed at the front of the housing, the blank bezel defining a closed front end of the cassette.

13 . The splice cassette of claim 1 , further comprising:

a first cable secured to the cable anchor region, the first cable including at least a first fiber extending into the first interior and routed to the first splice region; and

a second cable secured to the cable anchor region, the second cable including at least a second fiber extending into the first interior and routed to the first splice region to be spliced to the first fiber.

14 . The splice cassette of claim 13 , wherein the first cable and second cables are both secured to the first anchor position.

15 . The splice cassette of claim 13 , wherein the first cable is secured to the first anchor position and the second cable is secured to the second anchor position.

16 . The splice cassette of claim 1 , further comprising first and second covers positioned over the respective first and second ends of the housing.

17 . The splice cassette of claim 1 , wherein the first anchor position is disposed at the first side of the rear and the second anchor position is disposed at the second side of the rear.

18 . A splice cassette comprising:

a housing including a base having a first major side and an opposite second major side, each of the first and second major sides extending along a length of the housing between a front and a rear;

a termination bezel disposed at the front of the housing;

a first splice region disposed at the first major side of the base;

a second splice region disposed at the second major side of the base, the second splice region being laterally offset from the first splice region;

a first anchor position disposed at the rear of the housing, the first anchor position including a first angled surface leading to the first major side of the base; and

a second anchor position disposed at the rear of the housing, the second anchor position including a second angled surface leading to the second major side of the base.

19 . The splice cassette of claim 18 , further comprising a splice holder mounted at the first splice region.

20 . The splice cassette of claim 19 , wherein the splice holder is configured to hold multiple single-fiber splices.

21 . The splice cassette of claim 19 , wherein the splice holder is configured to hold a multi-fiber splice.

22 . The splice cassette of claim 19 , wherein the splice holder is a first splice holder, and wherein the splice cassette further comprises a second splice holder mounted at the second splice region.

23 . The splice cassette of claim 22 , wherein the second splice holder is configured to hold multiple single-fiber splices.

24 . The splice cassette of claim 22 , wherein the second splice holder is configured to hold a multi-fiber splice.

25 . The splice cassette of claim 18 , wherein the first and second splice regions include splice holder mounting arrangements that include releasable retention arrangements.

26 . A cassette comprising:

a housing extending along a length between a front and a rear, extending along a width between opposite first and second sides, and extending along a height between opposite first and second ends, the housing defining a first interior open at the first end of the housing and a second interior open at the second end of the housing, each of the first and second interiors extending along at least a majority of the length and along at least a majority of the width;

a termination bezel disposed at the front of the housing;

wherein the first and second interiors are equal in size and are on opposite sides of an interior bulkhead;

first and second covers positioned over the respective first and second ends of the housing; and

a cable anchor region disposed at the rear of the housing, wherein the cable anchor region comprises a first anchor position at the first side of the rear and a second anchor position at the second side of the rear, the first and second anchor positions communicating with the first and second interiors, respectively.
