QSFP28-100G-SR4 is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP28 Transceiver for IEEE 802.3bm,100GBASE SR4 Applications. The QSFP28 full-duplex optical module offers 4independent transmit and receive channels, each capable of 25.78125Gbps operation for an aggregate data rate of 103.125Gbps 70m using OM3 fiber. These modules are designed to operate over multimode fiber systems using 850nm VCSEL laser array. An optical fiber ribbon cable with an MPO/MTPTM connector can be plugged into the QSFP28 module receptacle. QSFP28 SR4 is one kind of parallel transceiver which provides increased port density and total system cost savings.
