Abstract: An optical module for channel express/add and a channel express/add method at an OADM(Optical Add-Drop Multiplexer) node using the same are provided to perform the same function as an exiting module by using one multiplexer, and to minimize power consumption by not requiring a temperature control circuit unit. A multiplexing/demultiplexing unit(230) demultiplexes a multiplexed optical signal having plural wavelength components or multiplexes plural different wavelength optical signals. Plural 1 x 2 switch units(250-1 to 250-n) induce each of the demultiplexed wavelength component optical signal to a first output terminal, and output the induced signal. The 1 x 2 switch unit receives a new wavelength component optical signal through a second output terminal. Plural reflectors(260-1 to 260-n) reflect the optical signal outputted to the first output terminal, to be fed back to the multiplexing/demultiplexing unit via the 1 x 2 switch unit.
