QSFP 40G SR4 400m

The QSFP+ 40G-SR4-400m module is a highly integrated 4x10G transceiver focused on reach, bandwidth, density and cost for high port-count 40G systems, and client-side 40G interfaces. Each lane can operate at 10.3125Gbps up to 300m using OM3 fiber or 400m using OM4 fiber. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38-contact edge type connector. The optical interface uses a 12-fiber MTP/MPO connector.
