Patent ID: 8457493

Claim:
An optical communication system, comprising: a master station is coupled to a plurality of slave stations by an optical fiber network including an optical splitter, wherein the optical fiber network further includes a reach extender transmitting and receiving between the master station and the slave stations, wherein the master station includes a first bandwidth control section which, based on uplink signal transmission requests from the slave stations, determines a first data amount of an uplink signal which each of the slave station transmits in a first cycle, wherein the reach extender includes: a distance measurement section which measures a transmission distance or a transmission time between the reach extender and each of the slave stations; and a second bandwidth control section which, based on uplink signal transmission requests from the slave stations and the first data amount, determines a second data amount and transmission timing of an uplink signal which each of the slave station transmits in a second cycle, and wherein each of the slave stations, based on a data amount and transmission timing which the distance measurement section and the second bandwidth control section determined in a plurality of the second cycles, transmits to the master station an uplink signal with a data amount which the first bandwidth control section determined in the first cycle.
