The 10GigE LAN Trunk Module is a single port 10 Gigabit Ethernet card that connects to the transport network via an optical interface. The optical connection is made using a small form factor pluggable transceiver (XFP) that is available in the following reaches: 300 meters, 10km, 40km and 80km. For DWDM networks, an XFP is also available with a reach up to 80km.
The 10GigE LAN Trunk Module is designed to handle jumbo Ethernet frames up to 9022 byes in length (including headers and FCS). Transmission of data to the MD8000 dual switch controllers is accomplished using a 10Gbps internal electrical interface to the chassis backplane.
Using a mid-plane chassis architecture, the 10GigE LAN Trunk Module uses a separate optical rear board to connect to the transport network.
