SFP+ (Small Form-factor Pluggable Plus) is a compact, hot-pluggable transceiver used in networking equipment. It supports data rates of up to 10 Gbps and is commonly used for high-speed connections in data centers and enterprise networks. SFP+ modules can transmit data over various media, including fiber optic and copper cabling, making them versatile for different networking needs. The SFP+ interface is designed to be compatible with existing SFP modules, allowing for easy upgrades. It is widely used in Ethernet and Fibre Channel applications, providing a reliable solution for connecting switches, routers, and servers in modern networking environments.
