Basic Network Connections
Connecting the SFP Ports
Small Form-Factor Pluggable (SFP) modules are devices that plug into the router SFP connectors shown
in
Figure 6-2
. The transceiver connects the electrical circuitry of the module with the optical or copper
network.
The SFP module used on each port must match the wavelength specifications on the other end of the
cable, and the cable must not exceed the stipulated cable length for reliable communications.
Use only Cisco SFP transceiver modules with the router. Each SFP transceiver module supports the
Cisco Quality Identification (ID) feature which allows a Cisco switch or router to identify and validate
that the transceiver module is certified and tested by Cisco.
Warning
Class 1 laser product.
Statement 1008
Caution
Do not remove the dust plugs from the fiber-optic SFP module port or the rubber caps from the
fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module
ports and cables from contamination and ambient light.
Caution
Cisco recommends that you not install or remove the SFP module while the fiber-optic cable is attached
to it because of the potential damage to the cables, to the cable connector, or to the optical interfaces in
the SFP module. Disconnect the cable before you remove or install an SFP module.
Materials and Tools You Supply
You must provide these tools and materials to install the SFP transceiver module:
•
Wrist strap or other personal grounding device to prevent ESD occurrences.
•
Antistatic mat or antistatic foam to set the transceiver on.
•
Fiber-optic end-face cleaning tools and inspection equipment. For complete information on
inspecting and cleaning fiber-optic connections, see the white-paper document at this URL:
