PURPOSE: An access scheduling method between terminals in an optical star-network is provided to transmit data on the basis of a transmission table that is written by a scheduler, thereby efficiently performing an optical access process without wavelength collisions in a receiving end. CONSTITUTION: A fixed wavelength transceiver transmits receiving terminal information to a scheduler(410). The transceiver arrays terminals connected to the scheduler at a longitudinal axis and a lateral axis of a table(420). If terminals arrayed at the longitudinal axis want to transmit data to terminals arrayed at the lateral axis, intersecting points between the longitudinal axis and the lateral axis are obtained(430). The transceiver sequentially selects the intersecting points as many as the number of transmitters and receivers of the arrayed terminals as moving in horizontal/vertical directions of the table(440). Among intersecting points that are not selected, the transceiver additionally selects intersecting points as many as the number of residual channels of the terminals(450). The transceiver transmits the table to all the terminals connected to an optical star-network(460). |
