QSFP (Quad Small Form-factor Pluggable): Four-lane SFP interface (QSFP), QSFP was created to meet the market demand for higher density, high-speed pluggable solutions.

QSFP can be used as a fiber optic solution, and the speed and density are better than the 4-channel CX4 interface. With four channels of data transfer at 10 Gbps per lane at the same port volume of the XFP, QSFP can be as dense as four times the XFP and three times the SFP +. The QSFP interface with 4 channels and higher density than the CX4 has been adopted by the InfiniBand standard.
