The SONT 400G QSFP112 DR4(QM3P4-FD5C) optical transceiver is a 4-channel electrical, 4-channel optical, pluggable, single mode fiber, QSFP112 transceiver designed for 400 Gigabit Ethernet applications. Each electrical data lanes or optical lanes supports 106.25Gbps. An optical fiber cable with an MPO-12 connector can be plugged into the module receptacle. Proper alignment is ensured by the guide pins inside the receptacle. These high-performance transceiver modules are designed to operate over single mode fiber (SMF) systems using a 1310nm wavelength, allowing communication up to 500 meters over single mode optical fiber cable. These modules are suitable for medium-range SMF data communication and interconnect applications.
