1. A cable arrangement comprising:
a protective enclosure extending along a length between opposite first and second ends, the protective enclosure being elongate along the length, the protective enclosure defining an environmentally sealed interior;
a wave division multiplexer disposed within the environmentally sealed interior of the protective enclosure, wherein a majority of the environmentally sealed interior of the protective enclosure is the wave division multiplexer;
a plurality of single-fiber optical connectors disposed external of the protective enclosure;
a plurality of optical fibers optically coupled to the wave division multiplexer, the plurality of optical fibers extending outwardly through the second end of the protective enclosure to respective ones of the plurality of single-fiber optical connectors;
an input single-fiber optical connector disposed external of the protective enclosure; and
an input fiber extending from the input single-fiber optical connector to the first end of the protective enclosure, the input fiber also being optically coupled to the wave division multiplexer so that optical signals carried over the input fiber are divided onto the plurality of the optical fibers.
