摘要:A cross-connection device has two three-port optical circulators for beingsupplied with wavelength-division-multiplexed optical signals each having a plurality ofwavelengths from respective input ports, a fiber grating mirror inserted between thethree-port optical circulators, for reflecting only an optical signal having a certainwavelength and passing optical signals having other wavelengths, a fiber grating mirrorcontroller for controlling the wavelength reflected by the fiber grating mirror, and twooutput ports for outputting cross-connected wavelength- division-multiplexed opticalsignals from the optical circulators. The fiber grating mirror controller controls thetemperature and pressure applied to the fiber grating mirror to select the wavelengthreflected by the fiber grating mirror. The fiber grating mirror may comprise a plurality offiber grating mirrors for reflecting different wavelengths to cross-connect a desirednumber of optical signals of the supplied wavelength-division-multiplexed optical signals.
