10 Gbps-class PON systems, including 10G-EPON and XG(S)-PON, are being introduced to optical access
networks. To reduce cost and improve system reliability, both a high-power budget and network
protection are required. We developed OLT transceivers with a high launched power of +6.7 dBm that
also achieved a good receiver sensitivity of −30.9 dBm by adopting an auto-switching fast/slow AGC
circuit. In addition, N:1 Type B protection was demonstrated on a 10G-EPON system. We achieved hitless
protection by providing fast protection switching in under 50 ms.
