SFP+ (Small Form-factor Pluggable Plus) is a high-speed, high-density, small form-factor transceiver used for data communication over fiber optic cables. It is an enhanced version of the SFP transceiver, offering up to 10 Gbps data rate and up to 300 meters transmission distance. SFP+ is commonly used to connect servers and switches in data centers, and is also used in storage area networks (SANs). It is compatible with both single-mode and multi-mode fiber cables, and supports a variety of protocols such as Ethernet, Fibre Channel, and InfiniBand. SFP+ is a cost-effective solution for high-speed data transmission over long distances.
