Abstract :
High reliability, low cost and TDM service supporting are the vital factors for Ethernet PONs to be deployed in FTTB (fiber to the business) and FTTB+H (fiber to the business and home) environments. To focus on high reliability and low cost, a novel protection scheme for the Ethernet PONs is proposed in this paper. Compared with the APON protection schemes recommended in ITU G.983.1 and SDH/SONET protection schemes, the novel scheme is more bandwidth-efficient, economical, flexible, and reliable.
