Pilot service and Efficient OEO-based Remote Terminal Providing a Higher Power Budget of an Asymmetric 10/1G-EPON

This paper proposes the design of an efficient optical-electrical-optical (OEO)-based remote terminal (RT) that can provide the higher power budget required for a long- reach transmission in an asymmetric 10 Gbit/s Ethernet passive optical network (10/1G-EPON). The current 10/1G- EPON specification supports a maximum physical distance of only 20km in a 32-way split due to a power budget limitation. However, many service providers prefer a transmission reach of over 40km in a 64-way split for an efficient access network design. In this paper, the proposed OEO-based RT provides quad-port architecture for a cost-effective design, supports a high power budget of 58 dB through 3R signal regeneration, and offers over a 50 km reach and 128-way split per port with no modification of a legacy 10/1G-EPON system. In addition, it can satisfy a packet loss rate (PLR) of 10 -10 in the downstream and upstream paths. The current 1G-EPON RT included within this proposed 10/1G-EPON RT is being the pilot service at a large residential apartment over 2,000 subscribers.
