First demonstration of 10G-EPON and GE-PON co-existing system employing dual-rate burst-mode 3R transceiver

Novel 10G-EPON dual-rate burst-mode 3R transceiver with receiver sensitivity of -31.2dBm for 10.3Gb/s and -35.6dBm for 1.25Gb/s was developed. 10G-EPON and GE-PON coexisting system of 32x ONUs with loss budget of 33.5dB was successfully demonstrated.

Single platform 10G-EPON 10.3-Gbps/1.25-Gbps dual-rate CDR with fast burst-mode lock time employing 82.5 GS/s sampling IC and bit-rate adaptive decision logic circuit

We demonstrate a novel 10G-EPON dual-rate CDR using single 82.5 GS/s sampling IC and dual-rate decision logic that achieves rapid burst-mode lock time of 37 ns at 10.3 Gbps in BER=10⁻³ and of 64 ns at 1.25 Gbps in BER=10⁻¹² via dynamically phase and bit-rate varied optical packets.

1.25/10.3Gbps dual rate algorithm for 10G-EPON burst-mode CDR

We present new dual rate algorithm for a burst-mode CDR and successfully achieved rapid burst-mode data recovery of less than 16 ns at 1.25 Gbps and of less than 6.4 ns at 10.3 Gbps in the same platform.

Dual-rate burst-mode optical receiver and CDR technologies for next-generation 10G-EPON systems

We review and update recent progress of 10G-EPON compliant dual-rate burst-mode optical receiver and CDR technologies as the key devices enabling co-existence with 10.3Gbps-based high-speed upstream transmissions and 1.25Gbps-based legacy GE-PON based ONUs. The dynamic performance results of a single platform 10.3G/1.25G dual-rate burst-mode 3R receiver are also presented.
