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.
