QSFP+ is a hot-pluggable high-density transceiver which provides 4 channels of traffic in each direction (Tx and Rx). QSFP+ supports up to 14 Gb/s per channel for applications such as 40G Ethernet, InfiniBand QDR or FDR, and OTN OTU3. Both multimode and single mode versions of the QSFP+ module are available, as well as QSFP-based active optical cables (40G Quadwire and 56G Quadwire).
