Abstract
An optical communication assembly has an optical cross connect coupled to a first, a second, a third and a fourth set of optical fibers. A first demultiplexer is coupled to a first input fiber and the first set of optical fibers and a second demultiplexer is coupled to a second input fiber and the second set of optical fibers. A first multiplexer is coupled to a first output fiber and the third set of optical fibers. A second multiplexer is coupled to a second output fiber and the fourth set of optical fibers. A first set of attenuators is coupled to the third set of optical fibers and a second set of attenuators coupled to the fourth set of optical fibers.
