40GbE QSFP+ Transceiver Modules

Quad Small Form-factor Pluggable or QSFP+ is a low profile, hot-pluggable transceiver used for data communications applications. It is used to connect switches, network, computers and servers distances of 10km.  QSFP+ transceivers are designed to support Serial Attached SCSI, 40G Ethernet, PCIe, 20G/40G Infiniband, and other communications standards.

Use only MTP/MPO 9/125 single-mode fiber optic cables with 40GBASE-LR4 transceivers and MTP/MPO OM3 50/125 MMF fiber optic cables with 40GBASE-SR4 transceivers. Please note to use crossover cables when selecting MTP/MPO cables. Using the wrong fiber type could damage your hardware.

We also carry a full line of QSFP+ Copper Cables.
