Abstract
PURPOSE:To increase the capacity of information processing network, by using light emitting elements having a plurality of different oscillation wavelengths and transmitting the data with different functions with optical signals different in oscillation wavelengths, between stations. CONSTITUTION:In the data way of loop, 4 wavelengths in lambda1-lambda4 are used, and the data different in function are transmitted with the optical signal different in the wavelength. The data signal different in the function is converted into optical signals different in the wavelength at electrooptical conversion sections 26, 27 and transmitted to the fiber of the transmission line via an optical distributor 14. The optical signal transmitted through the fiber enters a branching device 20 via an optical branch device 13. The optical signal in lambda1-lambda4 branched in converted into electric signal at opticalelectro conversion sections 22, 23, 24, 25. Thus, the high speed transmission of data different in function is made possible between stations by using the optical transmission line of loop shape, allowing to constitute the information processing network of large capacity.
