Abstract
A closure interconnects at least one optical fiber of a feeder cable with two or more optical fibers of a distribution cable at a local convergence point in an optical network. The closure includes a frame defining a longitudinal axis and a plurality of mounting surfaces. The closure further includes a fiber coupling area adjacent one of the mounting surfaces and a fiber management area adjacent another one of the mounting surfaces. The fiber coupling area includes at least one coupler module for splitting an optical signal carried on the optical fiber of the feeder cable into different optical signals carried on the two or more optical fibers of the distribution cable. The optical fibers of the distribution cable may be pre-connectorized drop cables, connectorized pigtails that are field terminated to fanout connectors, or optical fibers that are field terminated by mechanically splicing the optical fibers to drop cables.
