Differences between 10GE LAN and 10GE WAN

1. 10GE LAN services: Ethernet MAC frames are processed based on 66B/64B line coding and then are directly transmitted over an optical fiber. 10GE LAN services are mainly used for interconnection between LANs and used in point-to-point application scenarios using fibers or WDM equipment.
2. 10GE WAN services: Ethernet MAC frames are processed based on 66B/64B line coding, encapsulated into standard SDH/SONET frames, and then directly transmitted over an optical fiber. 10GE MAN services are mainly used for interconnection between LANs or MANs and used in point-to-point application scenarios using fibers or SDH/WDM equipment.
3. For the WDM system, 10GE WAN services can be considered 10G SDH signals. Therefore, SDH signals need to be selected on the client side.
4. 10GE LAN signals are also Ethernet signals. Therefore, LAN signals need to be selected on the client side.
5. The payload rate of 10GE LAN signals is 10.3125 Gbit/s while that of 10GE WAN signals is 9.953 Gbit/s.
