AddOn 1CH 1550 LC UPC Circulator Transceiver

This circulator is a nonreciprocal passive component that transmits light in only one direction. Circulators are used to increase transmission capacity of existing networks by converting bi-directional signals through a single fiber. This allows the transmission capacity of the network to be doubled without the need for deploying additional fibers, which has become increasingly expensive. They exhibit high isolation and low insertion loss. Circulators can be used alongside of mux/demux devices, optical add/drop, and other applications.
