Ethernet Line Cards
8-port 10-Gigabit Ethernet (8x10GE) 80-Gbps Line Rate Card
The 8-port 10-Gigabit Ethernet (8x10GE) 80-Gbps line rate card has eight 10-Gigabit Ethernet XFP
module ports. One 10-Gigabit Ethernet port connects to an XAUI interface on each of the eight NPUs.
The 8x10GE 80-Gbps line rate card supports WAN PHY and OTN modes as well as the default LAN
mode.
The 8x10GE 80-Gbps line rate 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 2-23
shows the block diagram for the 8x10GE 80-G line rate card, and
Figure 2-24
shows the
front panel connectors and indicators.
