The QSFP+ is a compact, hot-pluggable, protocol-independent transceiver used for data communications applications. It interfaces a network device (switch, router, media converter or similar device) to a fiber optic cable. It is an industry format jointly developed and supported by many network component vendors. QSFP+ transceivers are designed to support Serial Attached SCSI, 40G Ethernet, 20G/40G Infiniband, and other communications standards.
