Optical cross-connect equipment

摘要

Optical cross-connect equipment in which the intensity of a signal light input to optical amplifiers is held constant. Optical cross-connect equipment includes an optical pre-amplifier; a demultiplexer for demultiplexing an input multi-wavelength signal light into wavelength-split lights each having different wavelength; and a routing portion for routing each wavelength-split signal light having different wavelength to a desired output port. The routing portion further includes a control light generator for generating control lights corresponding to the signal lights split by the demultiplexer; a route switch to switch a route for each split signal light having different wavelength to output; an optical amplifier for amplifying each signal light output from the route switch; a control light insertion portion for inserting the control light generated by the control light generator; and a wavelength selector for selecting an output of the control light insertion portion having a wavelength assigned to the wavelength selector to forward to an output port.
