ABSTRACT:
The present invention relates to a fixed-length cell transmission system, a fixed-length cell transmitting unit and a fixed-length cell receiving unit. The fixed-length cell transmitting unit determines at least one optical transmitting section to be put to use, on the basis of band information of an inputted fixed-length cell to drive that optical transmitting section and sends the inputted fixed-length cell to that optical transmitting section. The fixed-length cell receiving unit is coupled through an optical transmission line to the fixed-length cell transmitting unit and is equipped with a plurality of optical receiving sections for converting a fixed-length cell of an optical signal into an electric signal and outputting the converted electric signal. In addition, the fixed-length cell receiving unit drives the optical receiving section corresponding to the optical transmitting section to be put to use in the fixed-length cell transmitting unit. The optical transmitting section and the optical receiving section are determined in accordance with the operating band at the transmission. Accordingly, this arrangement allows effective and flexible transmission of fixed-length cells.
