Demonstration of burst mode bit discrimination circuit for 1.25 Gb/s and 10.3 Gb/s dual-rate reach extender of WDM-TDM-hybrid-PON systems based on 10G-EPON.

We proposed a simple and cost-effective burst mode bit discrimination circuit for dual rate reach extender based on 10 gigabit Ethernet passive optical network. To distinguish the dual rate burst mode packets, periodic idle patterns which have specific frequency components in the frequency domain and radio frequency power detection technique were used. The burst mode dual rate upstream transmission was demonstrated to confirm the feasibility of our suggested method in a coexisted gigabit Ethernet passive optical network and 10 gigabit Ethernet passive optical network. We achieved the dual rate burst mode receiver sensitivity of - 32 dBm for 1.25 Gbit/s signal and -27 dBm for 10.3 Gbit/s signal, respectively.
