TS-QSFP-SR4 is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP+ Transceiver for InfiniBand QDR/DDR/SDR,12G/10G/8G/4G/2G fiber channel, PCIe and SAS Applications. The QSFP full-duplex optical module offers 4 independent transmit and receive channels, each capable of 11.3Gbps operation for an aggregate data rate of 45.2Gbps 100m using OM3 fiber. These modules are designed to operate over multimode fiber systems using 850nmVCSEL laser array. An optical fiber ribbon cable with an MPO/MTP connector can be plugged into the QSFP module receptacle. QSFP+ SR4 is one kind of parallel transceiver which provides increased port density and total system cost savings.
