Table A-6 summarizes the optics and connectors used by the two 10-GE ports on the 2-Port 10-GE +
20-Port GE combination line card.
See Table A-2 for a list of all SFP modules supported on the 20x1GE ports on the 2-Port 10-GE + 20-Port
GE combination line card. and their operating parameters.

16-Port 10-Gigabit Ethernet Oversubscribed Line Card

The 16-Port 10-Gigabit Ethernet oversubscribed line card provides two stacked 2x4 cage assemblies for
SFP+ Ethernet optical interface modules. The 16 SFP+ modules operate at a rate of 10 Gbps (see
Table A-3).
Oversubscription results from port pairs sharing the same NPU. The oversubscribed port pairs are port
0:port 8, port 1:port 9, port 2:port 10, port 3:port 11, port 4:port 12, port 5:port 13, port 6:port 14, and
port 7:port 15. The maximum bandwidth per port pair sharing a single NPU is 14.62 Gbps (7.31 Gbps
per port).
With two RSP cards installed in the router, the 16-Port 10-Gigabit Ethernet line card can achieve greater
than a 2:1 oversubscription rate. Each port pair sharing an NPU can reach 7.31 Gbps per port, so the
maximum bandwidth with two RSPs in the system is 117 Gbps.
With a single RSP card installed in the router, the 16-Port 10-Gigabit Ethernet line card is an 80 Gbps
line rate card with a maximum line rate of 16 ports at 50 percent (2-1 oversubscribed).
The 16-Port 10-Gigabit Ethernet line card is available in a base version.
Each SFP+ cage on the 16-Port 10-Gigabit Ethernet line card has an adjacent Link LED visible on the
front panel. The Link LED indicates the status of the associated SFP+ port, as described in Table 2-1.
Figure 1-6 shows the front panel and connectors of the 16-Port 10-Gigabit Ethernet line card.
