| 摘要 |
A communication system comprises a wavelength multiplexing network having a plurality of transmission channels of different wavelengths, a plurality of nodes interconnected by the wavelength multiplexing network for performing data communications with other nodes using time slots into which time on each of the transmission channels is divided, each of the nodes having its transmitting wavelength fixed and unique to a node and its receiving wavelength set tunable, and a network controller for centrally controlling time slot allocation repeated for each frame to the nodes.
