The 10 Gbps-PON system with 10 G/1G coexistence capability is one of the most promised systems for next generation optical access networks. We successfully developed 10 G-EPON system for coexistence with existing 1 G-EPON ONU with 8.46 Gbps upstream throughput.

PON (Passive Optical Network) permits the economical deployment of FTTH (Fiber to the Home) networks by sharing a single optical subscriber line among multiple subscribers. Especially since 2002, the deployment of PON systems has grown rapidly. This paper introduces the current status of FTTH in Japan then proposes a redundant optical access system with APS (Automatic Protection Switching) over PON which enables PONs for FTTBus (Fiber to the Business).

In this paper, a fast wavelength switching protocol to deal with the RTT drift problem in WDM/TDM-EPON system is proposed. Estimated process time revealed one sixth reduction of the switching time can be available.
