<P>PROBLEM TO BE SOLVED: To provide a wavelength division multiplexing apparatus capable of simultaneously implementing a function for reproducing and relaying a wavelength multiplex optical signal, a function for separating a client optical signal from the wavelength multiplex optical signal and a function for multiplexing the client optical signal, in a simplified configuration rather than a conventional wavelength division multiplexing apparatus, and to provide an optical communication system equipped with the wavelength division multiplexing apparatus. <P>SOLUTION: The wavelength division multiplexing apparatus 110 includes: an optical wavelength separating section 111b for receiving an input optical signal, separating it into a first wavelength multiplex optical signal and a second wavelength multiplex optical signal and outputting these signals; an optical signal separating section 112a for inputting the first wavelength multiplex optical signal, separating it into a client transmission optical signal and a third wavelength multiplex optical signal and outputting these signals; an optical signal multiplexing section 112b for multiplexing the second wavelength multiplex optical signal and a client reception optical signal to output a fourth wavelength multiplex optical signal; and an optical wavelength multiplexing section 113a for transmitting an output optical signal obtained by multiplexing the third wavelength multiplexed optical signal and the fourth wavelength multiplex optical signal. <P>COPYRIGHT: (C)2011,JPO&INPIT |
