Optical ether constructed using paired couplers and paired fibers

摘要

An all optical transparent network is arranged such that each optical communication port can simultaneously and independently broadcast optical signals to, and receive optical signals from, any or all other optical communication ports on the network, and such that optical communications ports can arbitrarily and conveniently be added at distributed locations. The optical network constructed of paired 2x2 optical couplers that are cross-connected in a unique manner to form twin couplers, and/or NxN star couplers having at least one paired receiving and transmitting port such that each of the N communication ports communicates directly with each of the other communication ports.
