The QSFP can be used as a fiber optic solution with speed and density superior to the 4-channel CX4 interface. Since four channels of data can be supported at 10Gbps per channel at the same port volume of the XFP, the density of the QSFP can be 4 times that of the XFP product and 3 times that of the SFP+ product. The QSFP interface with 4 channels and higher density than the CX4 has been adopted by the InfiniBand standard.
