Summary: 
The function of optical wavelength selection is realized using a laser diode module which has an incorporated single mode fiber pigtail and an incorporated photodiode. One signal can be selected from two-wavelength multiplexed light signals with a channel spacing of 0.23 nm, and a crosstalk level of 30 dB. The laser diode in a module is tuned to the injection light, and the signal to noise ratio necessary for receiving 1 Gb/s signal is obtained when the received light power into fiber of the laser diode module is more than -35.9 dBm.
