The QSFP (Quad Small Form-factor Pluggable) interface is a high-performance, compact, hot-pluggable transceiver utilised for data communication applications. It is designed to carry Serial Attached SCSI, 40G Ethernet, QDR (40G) and FDR (56G) Infiniband, and other communications standards. QSFP modules increase the port-density by three times compared to SFP modules, providing significant space and cost savings. The QSFP transceiver offers four channels of data in one pluggable interface, each capable of transferring data at a rate ranging from 1 Gbps to 28 Gbps per channel. This allows for a total data transfer rate of 100 Gbps. The transceiver's design allows for easy and flexible expansion of network capacity. QSFP transceivers are equipped with an electrical interface to connect with the motherboard and an optical interface to connect with the network. The electrical interface uses a 38-contact edge type connector, while the optical interface utilises either a duplex LC connector or a MPO-12 connector.
