Demonstration of 10G-EPON and GE-PON Coexisting System Employing Dual-Rate Burst-Mode 3R Transceiver

In this letter, a novel 10 gigabit Ethernet passive optical network (10G-EPON) optical line terminal (OLT) dual-rate burst-mode reshaping, retiming, and regenerating transceiver was, for the first time, reported to completely meet the IEEE802.3 av 10G-EPON standards where the coexisting of 10G-EPON and gigabit Ethernet passive optical network (GE-PON) systems on the same fiber plant is specified. Newly developed 10G/1G dual-rate burst-mode avalanche photodiode preamplifier and dual-rate 82.5-GS/s burst-mode clock and data recovery achieved the high receiver sensitivity and the wide burst dynamic range of -31.2 dBm/25.2 dB (at bit-error rate (BER) = 1 X 10^-3) for 10.3 Gb/s and -35.6 dBm/26.3 dB (at BER = 1 x 10^-12) for 1.25 Gb/s. Moreover, 10G-EPON and GE-PON coexisting system of 32 x optical network units with loss budget of 33.5 dB was successfully demonstrated.
