Abstract
Research and development has been performed on a new system COPM that links signals from LAN to an ultra high speed network of tera-bit class, and on the element technology required thereon. This paper summarizes the achievements. The transmission system using the COPM modulates beam signals by using image signals of 155 mega-bits per second; compresses the modulated beam pulse strings as much as sixteen times to transmit the light pulse as the light pulse of 2.5 giga-bits per second; and the pulses are expanded again at the receiver side to demodulate them into electric signal to project them as images on a TV screen. This demonstration was performed successfully. In addition, in order to mitigate the problems in raising the compression rate only in the beam zone, a proposal was made on a hybrid type compression device that combines the electric compression with the compression in the beam zone in series. As a result, it was shown that compression of up to about 10 giga-bit per second is possible in the electric zone by using an electric memory. Further research and development has been advanced on the element technologies, and the initial objective has been nearly achieved. (NEDO)
