Difference between client-side 10GE LAN and 10GE WAN services on the TQX board

10

Both 10GE LAN and 10GE WAN services are Ethernet services but have different service rates. The rate of 10GE LAN services is 10.31 Gbit/s and that of 10GE WAN services is 9.95 Gbit/s. Set the client-side service type of the TQX board based on the actual rate of received services.

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.

Major difference between 10GE LAN services and 10GE WAN services in OTN equipment
Their bottom-layer encapsulation structures are different. A 10GE WAN signal contains an SDH/SONET encapsulation header but a 10GE LAN signal does not. 10GE LAN service: Ethernet MAC frames are processed based on 66B/64B line coding and then are directly transmitted over an optical fiber at a rate of 10.31 Gbit/s. 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 at a rate of 9.95 Gbit/s.

Client-side service type for OTN service boards when 10GE WAN services are received
When 10GE WAN services are received, the client-side service type for OTN service boards must be 10GE WAN or STM-64.

Line-side settings for changing the tributary service type from 10GE LAN to 10GE WAN on an OSN 8800
When the tributary service type of an OSN 8800 is changed from 10GE LAN to 10GE WAN, the line rates of the related channels on line boards must be changed to standard mode.

Differences between the data frames of 10GE LAN and data frames of 10GE WAN services supported on the OSN 6800
10GE LAN services use Ethernet data frames, while 10GE WAN services use SDH data frames.
