* A media converter is a device that converts signals between different media types, such as fiber and copper. It can be used to connect a fiber cable into a network switch without available SFP ports by converting the optical signal to an electrical signal that can be transmitted over a UTP cable. Therefore, option A is the correct answer.
* Installing an additional transceiver module and using GBICs is not a cost-effective solution, as it requires purchasing and installing additional hardware components. GBICs are older and larger versions of SFPs that provide similar functionality. Therefore, option B is incorrect.
* Changing the type of connector from SC to F-type is not a valid solution, as it does not address the issue of the switch not having available SFP ports. SC and F-type are different types of connectors used for fiber cables, but they do not affect the compatibility with the switch. Therefore, option C is incorrect.
* Using a loopback adapter to make the connection is not a valid solution, as it does not connect the fiber cable to the switch. A loopback adapter is a device that connects the transmit and receive pins of a port to test its functionality. It is used for troubleshooting purposes, not for network connectivity. Therefore, option D is incorrect.
