QSFP28-100G-PSM4 is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP28 transceiver for 100G Ethernet  Applications. The QSFP28 full-duplex optical module offers 4 independent transmit and receive channels, each capable of 26Gbps operation for an aggregate data rate of 104Gbps 10km using single mode fiber. These modules are designed to operate over single mode fiber systems using  DFB laser array. An optical fiber ribbon cable with an MPO/MTPTM connector can be plugged into the QSFP28 module receptacle. QSFP28 PSM4 is one kind of parallel transceiver which provides increased port density and total system cost savings.
