Optical fiber distribution shelf assembly containing a modular optical switch

A fiber distribution shelf containing an optical switch within the confines of the shelf structure. The fiber distribution shelf is part of an optical fiber administration system where various stages of switching are used to interconnect an optical time domain reflectometer to the optical fibers that terminate on a fiber distribution shelf within a fiber administration system. By having the shelf optical switch entirely contained within the shelf structure of a fiber distribution shelf, a unique configuration is provided that greatly reduces the size and complexity of the overall fiber administration system.
