SFP+ (Small Form-factor Pluggable Plus) is a high-speed, high-density, small form-factor transceiver used for data communication applications. It is an enhanced version of the SFP transceiver, offering up to 10 Gbps data rate and up to 8 Gbps Fibre Channel rate. It is compatible with both multimode and single-mode fiber cables and supports a wide range of wavelengths. It is also backward compatible with existing SFP transceivers. SFP+ transceivers are used in a variety of applications, including Ethernet, Fibre Channel, InfiniBand, and SONET/SDH. They are ideal for high-speed data center applications, providing high-speed, low-power, and reliable data transmission.
