10G SFP+ (Enhanced Small Form-factor Pluggable) is a compact, hot-pluggable optical transceiver module. It serves as an interface between a network device (such as a switch, router, or network card) and fiber optic or copper cabling. Supporting various ranges from short-distance multimode fiber to long-distance single-mode fiber (up to 120km), it is widely deployed in data centers, enterprise networks, and telecommunications for high-speed, reliable connectivity.
