Abstract

A glass-fiber coupler module includes a cassette mount, a mounting panel pivotally coupled to the cassette mount, a front panel coupled to the cassette mount, and a splitter coupled to the second side of the cassette mount. A first side of the cassette mount defines a storage area configured to receive spare lengths of glass fibers. The mounting panel is configured to support a first plurality of couplings. The front panel is configured to support a second plurality of couplings. The splitter is configured to receive glass fibers routed from the second end of at least one of the couplings of the first plurality, the splitter also configured to output at least two glass fibers to the first ends of at least two of the couplings of the second plurality.

Claims

1. A glass-fiber coupler module comprising:

a cassette mount having a first side and an opposite, second side, the first side of the cassette mount defining a storage area configured to receive spare lengths of glass fibers;

a mounting assembly pivotally coupled to the cassette mount, the mounting assembly being configured to pivot from a first position covering the storage area to a second position providing access to the storage area, the mounting assembly being configured to support a first plurality of couplings, each coupling of the first plurality being configured to receive a plug at each of a first end and a second end;

a front panel coupled to the cassette mount, the front panel being configured to support a second plurality of couplings, each coupling of the second plurality being configured to receive a plug at each of a first end and a second end;

a splitter coupled to the second side of the cassette mount, the splitter configured to receive glass fibers routed from the second end of at least one of the couplings of the first plurality, the splitter also configured to output at least two glass fibers to the first ends of at least two of the couplings of the second plurality;

a first glass fiber extending from the second end of one of the couplings of the first plurality, the first glass fiber being routed to the first end of a first of the couplings of the second plurality;

a second glass fiber extending from the second end of one of the couplings of the first plurality, the second glass fiber being routed to the splitter;

a third glass fiber extending from the splitter to the first end of a second of the couplings of the second plurality; and

a fourth glass fiber extending from the splitter to the first end of a third of the couplings of the second plurality.

2. The glass-fiber coupler module as claimed in claim 1, wherein all of the couplings in the first plurality are arranged in a row.

3. The glass-fiber coupler module as claimed in claim 1, wherein all of the couplings in the second plurality are arranged in a row.

4. The glass-fiber coupler module as claimed in claim 1, wherein the storage area includes at least one direction-changing element.

5. The glass-fiber coupler module as claimed claim 1, wherein cable ducts are arranged on opposite sides of the mounting assembly.

6. The glass-fiber coupler module as claimed in claim 1, wherein the cassette mount is at least as wide as the mounting assembly including the cable ducts.

7. The glass-fiber coupler module as claimed in claim 1, wherein the mounting assembly is configured to be locked into the first position.

8. The glass-fiber coupler module as claimed claim 1, further comprising V-shaped extensions extending from the mounting assembly.
