Ethernet Line Cards
4-Port 10-Gigabit Ethernet (4x10GE) Line Card
The 4-port 10-Gigabit Ethernet (4x10GE) line card has four 10-Gigabit Ethernet XFP module ports. One
10-Gigabit Ethernet port connects to an XAUI interface on each of the four NPUs.
The 4x10GE line card is available in base, extended, and low-queue versions. All versions are
functionally equivalent, with the extended version of the line card providing typically twice the service
scale of the base line card.
Figure 2-21
shows the block diagram for the 4x10GE Line card, and
Figure 2-22
