Note
Coarse wavelength-division multiplexing (CWDM) SFP transceivers are color-coded based on
wavelength: gray (1470), violet (1490), blue (1510), green (1530), yellow (1550), orange (1570), red
(1590), and brown (1610).
Cisco Gigabit Ethernet high-speed WAN interface cards are designed for use in the following network
design scenarios:
•
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
Tip
For more information on possible network configurations using the Cisco Gigabit Ethernet high-speed
WAN interface card, see Cisco product documentation.
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:
Step 1
Confirm successful insertion of the SFP.
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
Step 2
Confirm that the router is powered down.
Step 3
Remove optical port plugs from the installed SFP.
Step 4
Use the appropriate cable (see
Table 35
) to connect to the installed SFP.
Note
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.
