SFP / SFP+ Transceiver

An SFP module (Small Form-Factor Pluggable) is a very compact, hot-pluggable transceiver module that can be used for both telecommunication and data communication. The SFP module is simply connected to the SFP port of a network device (e.g. switch or router) and, depending on the design of the SFP module, enables optical (fiber) or copper cable-based communication. The SFP format is therefore initially not tied to a specific transmission medium, but can be used flexibly, depending on the requirements, with fiber optic or copper cables. Therefore this format is supported by many manufacturers of network components. An SFP module also supports SONET, Gigabit Ethernet, Fiber Channel and other communication standards.
