- The Quad (4-channel) Small Form-factor Pluggable (often abbreviated as QSFP or QSFP+) is a compact, hot-pluggable transceiver used for data communications applications. It interfaces a network device motherboard (for a 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, supporting data rates from 4x10 Gb/s. The format specification is evolving to enable higher data rates model specified here offers 40G datarate over 4 independent full-duplex channels Up to 11.2Gbps data rate per wavelength
- The QSFP specification supports Ethernet, Fiber Channel, InfiniBand and SONET/SDH standards with different data rate options. QSFP+ transceivers are designed to support Serial Attached SCSI, 40G Ethernet, 20G/40G Infiniband, and other communications standards. QSFP modules increase the port-density by 3x-4x compared to SFP+ modules.

Notes:
- The receiver shall be able to tolerate, without damage, continuous exposure to a modulated optical input signal having this power level on one lane. The receiver does not have to operate correctly at this input power.
- Vertical eye closure penalty and stressed eye jitter are test conditions for measuring stressed receiver sensitivity. They are not characteristics of the receiver.
