Connecting Cisco Gigabit Ethernet High-Speed WAN Interface
Cards to the Network
To connect the Cisco Gigabit Ethernet high-speed WAN interface card to the network, perform the
following steps:
Confirm successful insertion of the SFP.
Step 1
Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is
connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 125
Confirm that the router is powered down.
Step 2
Remove optical port plugs from the installed SFP.
Step 3
Use the appropriate cable (see
Step 4
Note
LC Connector
In metropolitan-area network (MAN) backbones for low-cost, high-speed, and long-distance
connectivity
In multiprotocol WAN gateway routers for LANs
In same-building or same-campus wiring closets to achieve high-speed connectivity for
high-demand network segments
For short distances or loopbacks, network installations using 1000BASE-CWDM and
1000BASE-ZX SFPs may require 15-dBm attenuators to avoid over-powering the connection.
Calculate the power budget for the connection to determine which attenuator to use.
