40G 850nm 100m QSFP+ transceivers are designed for use in 40Gb/s links over multimode fiber. They integrate four channel VCSEL array and four channel PIN photodiode array; each channel can operate at 10.3125Gb/s up to 100m using OM3 or 150m using OM4 MMF. They are compliant with the QSFP+ MSA and IEEE 802.3ba 40GBASE-SR4. 40G 850nm 100m QSFP+ are compliant with RoHS.
