Abstract PURPOSE:To discriminate and process plural sets of peculiar information without confusion by sending each specific information outputted from plural optical signal transmission/reception terminal devices to one optical signal transmission/ reception terminal device as difference frequency signals. CONSTITUTION:When data request is issued to each of other optical signal transmission/reception terminal devices 2 from one high-order optical signal transmission/reception terminal device 1 at first, each transmission/reception terminal device 2 sends optical signals having predetermined peculiar transmission frequencies f1, f2...fn to the transmission/reception terminal device 1. then the transmission/reception terminal device 1 discriminates each transmission/ reception terminal device 2 to process the peculiar information. Further, since the peculiar information measured by each transmission/reception terminal device 2 changes time by time, when deviations DELTAf1, DELTAf2...DELTAfn of the time wise changing information are sent with respect to the frequencies f1, f2...fn, the data is sent further in details.
