Other requirements
1G/10G coexistingEnergy efficientLong reach/wide area and high split ratio
Synchronous10G-EPONApplication to future mobile backhaul will be an attractive candidate Frequency synchronization is realized by using Synchronous Ethernet technology implemented into 10G-EPON systemTime synchronization of PON is realized by 802.1AS implementation
Highly reliable 10G-EPONHigh reliability is needed for higher-capacity and larger-splitting PON Progress of keep connection services i.e. video distribution, real-time gamingCost-effective redundant configuration can upgrade and replace OSU
Interoperable 10G-EPONSIEPON/G.epon compliant with some additional specification.The use of some interoperability test program for SIEPON/G.epon

Conclusions and Recommendations
The number of FTTH subscribers exceed 22.3 million now in Japan. That is expected to exceed 30 million by the end of March 2016.Development of optical broadband network will be facing a new era “Mobility” and “Cloud”10G-EPON is ready for commercial that has flexible system configuration and its feasibility was confirmed by some demonstrations and a field trial.
