ABSTRACT:
A crossconnect unit which includes a unit for inputting a plurality of coherent signals having a sub-signal added to a main signal after the sub-signal has been modulated by one of a group of modulation methods including a frequency modulation, a phase modulation, an intensity modulation and an amplitude modulation which are different from those applied to the main signal, a wavelength filter for extracting a desired signal from said plurality of coherent signals, a destination decoder for detecting the sub-signal from the extracted signal and extracting destination information, and apparatus for setting a signal path for the extracted signal based on the destination information.
