The QSFP (Quad Small Form-factor Pluggable) MSA (Multi-Source Agreement) defines a highly integrated 4-channel optical transceiver which would replace four standard SFP transceiver modules providing increased port density and total system cost saving. The device will support Ethernet, Fibre Channel and SONET/SDH standards with different data rate options. The QSFP MSA document specifies a transceiver module mechanical form-factor with latching mechanism and a host board SFP-like electrical edge connector and cage. The hot-pluggable module integrates four transmit and four receive channels with a standard MPO parallel optical connector. The QSP device features digital optical diagnostic capability to monitor the link performance. This highly integrated transceiver module will enable network equipment manufacturers to increase port density and system data throughput and consequently reduce costs per Gb/s significantly.
