Embodiment Construction
[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0038] see figure 2 As shown, the uplink / downlink optical receiving optical module and peripheral physical devices such as 10G uplink and downlink SERDES (SERializer / DESerializer, serializer), that is, the PHY (Physical Layer, physical layer chip) upstream receiving physical device specified in the 802.3AV standard 10G SERDES and optical modules, as external interfaces, are mainly used to receive uplink and downlink light on the PON side. 802.3FEC / PCS / RS / PON MAC, that is, the PHY, PON MAC and corresponding capture interface circuits specified in the 802.3AV standard, are connected to the 10G uplink and downlink SERDES, and are used to pass the received uplink and downlink light on the PON side through the 10G uplink and downlink SERDES Go to the OLT PCS module in 802.3FEC / PCS / RS / PON MAC to complete FEC decoding and PON message recov...
