<p>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 (160) is coupled to a first input fiber and the first set of optical fibers and a second demultiplexer (168) is coupled to a second input fiber and the second set of optical fibers. A first multiplexer (162) is coupled to a first output fiber and the third set of optical fibers. A second multiplexer (170) is coupled to a second output fiber and the fourth set of optical fibers. A first set of attenuators (152) is coupled to the third set of optical fibers and a second set of attenuators(152) coupled to the fourth set of optical fibers. The attenuators may consist of acousto-optic tunable filters and are controlled by an electronic feedback loop.</p> |
