Abstract

PURPOSE:To elevate a data transmission speed by making the wave length of a light transmission line multiplex, and transmitting a data in bit-parallel. CONSTITUTION:At the time of transmission, each bit of a transmission data of 1 byte is transmitted simultaneously to the transmitters 351-358, it is made multiplex by the wave combining unit 36, and is sent out to the light transmission line in bit-parallel. A receiving data is made to branch to the wave length lambda1-lambda8 by the branching filter 31, each wave length is provided to the receivers 321-328, respectively, it is photoelectrically converted, and is provided to the receiving data processing circuit 33. In this way, since the number of bits for the multiple degree portion of wave length is transmitted by 1 cycle, it is possible to remarkably elevate a data transmission speed.
