| Abstract: | We propose and analyze an economical half-duplex high speed Ethernet over PON access system. By inserting a fiber Bragg grate on the feeder fiber before the star coupler and adding a remote forward unit, the distance limit caused by CSMA/CD is reduced with low cost. Both theoretical analyses and simulation show that the throughput of this EPON system is as well as that of semiduplex high speed Ethernet LAN. |
