The Quad Small Form-factor Pluggable (QSFP+) is a compact, hot-pluggable transceiver used for data communications applications. It interfaces a network device mother board (for a switch, router, media converter or similar device) to a fiber optic cable. It is a industry format jointly developed and supported by many network component vendors. QSFP+ transceivers are designed to support Serial Attached SCSI (SAS), 40G Ethernet, 20G/40G Infiniband, and other communications standards.[1]
