Abstract:
1. An optical communication system connecting a parent station and a plurality of child stations via an optical fiber network equipped with an optical splitter comprising a relay for relaying a signal for transmission/reception between the parent station and the plurality of child stations in said optical fiber network, said relay having a control unit including: a measuring unit for measuring a transmission distance or time to each child station; a determining unit for determining a timing when the child station transmits a signal, in response to a transmission bandwidth request indicating a data amount waiting for transmission from the child station; and a signal processing unit for processing a signal received from the child station and transmitting the processed signal to the parent station, wherein: said relay notifies each child station of the timing determined by said determining unit after measurement by said measuring unit; upon reception of a burst signal constituted of a header and a payload from the child station at the notified timing, said signal processing unit deletes a portion of the header of the received burst signal in accordance with the timing, and converts the received burst signals into a series of signals by inserting a dummy signal into the deleted area and a gap area between received burst signals to be transmitted to the parent station; and the parent station receives the series of signals converted by said relay from signals transmitted from the plurality of child stations.
