OPTICAL SIGNAL BRANCHING CIRCUIT AND OPTICAL COMMUNICATION NETWORK

摘要

By using the wavelength multiplexing technique and a wavelength router, a sophisticated network structure such as full mesh is built on a ring-shaped optical fiber network and the problem of isolation shortage generated can be solved. By using a wavelength router having two sets of optical add/drop multiplexers, each consisting of (N-1) sets of a pair of add means and drop means, a communication route of full mesh is built between N nodes.
