QSFP (Quad Small Form-factor Pluggable): Quad-SFP interfaces (QSFP), QSFP is to meet the market demand for higher-density, high-speed pluggable solutions born.

This four-channel pluggable interface transfer rate reached 40Gbps. Many XFP mature key technologies are applied to the design.

QSFP optical fiber can be used as a solution, and the speed and density are better than 4-channel CX4 interface. Since at the same port XFP volume per channel supports data transmission speed of 10Gbps four channels, so that, QSFP can reach 4 times the density of the product XFP, SFP+ product 3 times. With a 4-channel and high density QSFP than CX4 interface has been adopted by InfiniBand standard.
