- Abstract
- 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.
