SFPs and GBICs are modules that are inserted into network switches and routers to connect fiber cables. SFPs connect fiber cables that have LC connectors, which are smaller than the SC connectors used in conjunction with GBICs. When you need to convert from LC to SC, you can use an SFP-to-GBIC converter instead of running a new fiber line, especially because fiber lines are often run underground.

1 Insert the SFP module into the SFP-to-GBIC converter.

2 Insert the GBIC module into the SFP-to-GBIC converter.

3 Connect a fiber cable with an LC connector to the SFP. Push until it clicks into place.

4 Connect a fiber cable with an SC connector to the GBIC. Push until it clicks into place.

5 Turn on the SFP-to-GBIC converter.
