5.3 E1000-2-G Card
The E1000-2-G card uses GBIC modular receptacles for the optical interfaces. For details, see the
“5.8 GBICs and SFPs” section on page 5-14.
Figure 5-2 shows the card faceplate and a block diagram of the card.

The E1000-2-G Gigabit Ethernet card provides high-throughput, low-latency packet switchi ng of
Ethernet traffic across a SDH network while providing a greater degree of reliability through SDH
self-healing protection services. This enables network operators to provide multiple 1000-Mbps access
drops for high-capacity customer LAN interconnects. It enables efficient transport and co-existence of
traditional TDM traffic with packet-switched data traffic.
