PROBLEM TO BE SOLVED: To obtain an optical branching and inserting device which respectively control transmission wavelength of a plurality of wavelength multiplexed signal light for each wavelength and improving transmission characteristic deterioration.;SOLUTION: This optical branching and inserting device has: an optical demultiplexing means 4 for demultiplexing wavelength multiplex signal light inputted an input side optical fiber transmission line 2a; an optical receiver 6 for receiving desired wavelength signal light among the plurality of signal light demultiplexed by the optical demultiplexing means 4 and outputting an obtained received signal as a feedback signal to an upstream side optical branching and inserting device; an optical transmitter 5 for performing fine adjustment so as not to deteriorate the transmission characteristic of the desired wavelength signal light and outputting the signa light on the basis of a feedback signal transmitted from a downstream side optical branching and inserting device; and an optical demultiplexing means 3 for performing wavelength multiplexing of transmission signal light that passes through from the optical demultiplexing means 4 and the signal light outputted by the optical transmitter 5 and outputting a generated wavelength multiplex signal light to an output side optical fiber transmission line 2b.;COPYRIGHT: (C)2006,JPO&NCIPI
