Figure 12 Inserting the Gigabit Ethernet SFP GBIC Cables
Note There is no support for copper-based SFP GBICs (1000BASET) as these do not conform to the SFP GBIC standard and
have not been validated by Cisco.
Step 1 Remove the SFP GBIC plug.
Step 2 Attach the appropriate optical fiber cable directly to SFP GBIC module. You can use either simplex or duplex
connectors for most devices.
• Two cables are required for simplex connectors, one cable for transmit (TX) and one for receive (RX).
• One cable that has both TX and RX connectors is required for duplex connectors.
Use a Category 5 unshielded twisted pair cable with RJ-45 connector, if you are using a Cisco 1000BASE-T SFP.
Caution If you plan to use a GLC-LH-SM at distances greater than 984.25 feet (300 meters) over 50/125-micron or
62.5/125-micron multimode fiber, to prevent data transmission problems you must use the mode-conditioning
patch cord.
