PROBLEM TO BE SOLVED: To provide a facility for enhancing simultaneous transmissions of optical signals of different data rates such as, for example, OC48 and OC192 signals. SOLUTION: A stream of a first channel λi for carrying signals of different data rates and a stream of a second channel λy for carrying a signal having the same data rate are respectively supplied to inputs 31 and 32 of an asymmetrical wavelength synthesizer 130, interleaved at an output 33, and transmitted via an optical path 145. The synthesizer 130 reconfigures the signal to be processed, thereby making it ideally suited to offset problems of cladding mode when demultiplexing and multiplexing the signal streams as its advantage. |
