Transceiver-Based Gigabit Ethernet Cards
2-14 SmartEdge 1200 Router Hardware Guide
10 Gigabit Ethernet
The 10 Gigabit Ethernet (10GE) card is designed for traffic management, with the second generation of the
PPAs, each of which supports 1 GB of memory and can process data internally to match the speed of the
port, which runs at 10 Gbps. Any of the following types of 10-Gbps XFP transceivers are supported on the
port:
• 10000Base-SR
• 10000Base-LR
• 10000Base-ER
Table 2-11 lists the 10GE card specifications for the various XFP transceivers.
Caution Risk of data loss. You can corrupt the system if you attempt to install transceivers (GBICs,
SFPs, or XFPs) that are not purchased from Redback because these items have not been tested
with the SmartEdge router. To reduce the risk, install only the transceivers purchased from
Redback.
