Abstract
A device may include an input cable for receiving optical signals from a feeder cable, output cables for transmitting optical signals to a distribution cable, and a housing. The housing may include an optical splitter for splitting an input beam into a plurality of output beams, an input fiber segment for conveying the input beam from the input cable to the optical splitter, the input fiber segment excluding fiber loop slack, and output fiber segments for conveying the output beams from the optical splitter to the output cables using MT-APC connectors.
Claims20
A device comprising:
- an input cable for receiving optical signals from a feeder cable;
- output cables for transmitting optical signals to a distribution cable;
- and
- a housing, including:
- an optical splitter for splitting an input beam into a plurality of output beams;
- an input fiber segment for conveying the input beam from the input cable to the optical splitter, the input fiber segment excluding fiber loop slack;
- output fiber segments for conveying the output beams from the optical splitter to the output cables;
- a stress absorbing unit attached to the optical splitter and configured to guide first portions of the output cables toward an inside wall of the housing, and protect the first portions of the output cables against bending at angles that cause damage to the output fiber segments, the first portions of the output cables being inside the housing;
- and
- an output fan-out unit configured to connect the first portions of the output cables to second portions of the output cables and affix the first portions of the output cables to the housing such that pulling at the second portions does not detach the output fiber segments from the optical splitter.

A method comprising:
- receiving an optical signal from a feeder cable at a connector;
- routing the optical signal from the connector to a splitter inside a splitter container via an optical fiber cable, the optical fiber not including a fiber loop;
- splitting, at the splitter, the optical signal into a plurality of optical signals;
- routing the plurality of optical signals from the splitter to connectors via ribbon cables, the ribbon cables not including any fiber loop;
- outputting the plurality of optical signals from the connectors;
- preventing the ribbon cables from bending at angles that damage optical fibers inside the ribbon cables via a stress absorbing unit that is attached to the splitter and guides the ribbon cables from the splitter to a wall of the splitter container;
- and
- affixing the ribbon cables to the wall of the splitter container via a fan-out unit such that pulling at the ribbon cables does not detach the optical fibers from the splitter, the fan-out unit regrouping the optical fibers in the ribbon cables.
