What functionality does an SFP (Small Form-Factor Pluggable) port provide?

An SFP (Small Form-Factor Pluggable) port is designed to accommodate a range of transceiver modules that enable both copper and fiber connections. This versatility means that network administrators can choose the appropriate type of connection for their specific requirements. For instance, SFP modules can be used with optical fiber to facilitate long-distance communication, or with copper cabling for short connections. This flexibility is crucial in modern networking environments, allowing for scalability and adaptability according to the network needs.

The other options do not accurately reflect the functionality of SFP ports. While copper connections alone are supported, the capability to also accept fiber connections distinguishes SFP ports and makes them more widely applicable in various networking scenarios. Moreover, the power output of an SFP port is not inherently higher nor limited to a specific type of end device, but instead is dependent on the transceiver being used and its configuration within the network.
