OPTICAL TRANSMISSION MODULE AND OPTICAL TRANSMITTER FOR OPTICAL WAVELENGTH MULTIPLEX TRANSMISSION AND EXTENSION METHOD FOR THE OPTICAL TRANSMISSION MODULE IN THE OPTICAL TRANSMITTER FOR OPTICAL WAVELENGTH MULTIPLEX TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To provide an optical multiplex transmission system in a configuration matching the required scale. ;SOLUTION: A transmitter side is configured to be a module in the unit of systems comprising conversion means 12, 130, which convert a transmission signal into an optical signal with a wavelength particular to a system and an optical element 141 that receives the optical signal converted by the conversion means for a first input and composites the optical signal of the other system led to an optical path with the first input to obtain a composite optical signal, which are provided in the unit of system. Further, a receiver side is configured to be a module in the unit of systems comprising an optical element 441 that branches an optical signal with a particular wavelength from an optical signal with other wavelength among introduced optical signals and reception means 41, 42 that convert the optical signal with the particular wavelength branched by the optical element into an electric signal and obtains it as a received signal, which are provided in the unit of systems.;COPYRIGHT: (C)2003,JPO
