40GBASE-SR4 QSFP+ Transceiver Module for MMF

 SR QSFP+ modules supports link length of 100m and 150m respectively on laser-optimized OM3 and OM4 multimode fiber cable. It originally enables high-bandwidth 40G optical links over 12-fiber ribbon cables terminated with MPO/MTP multi-fiber connectors. It integrates four data lanes in each direction with each lane to give an aggregated 40 Gbps bandwidth. Each lane supports link length of 100m on OM3 multimode fiber to 150m on OM4 multi-mode fiber. The optical transmitter incorporates a 4-channel 850nm VCSEL laser, a 4-channel input buffer andlaser driver, control and bias blocks. The optical receiver incorporates a 4-channel PIN photodiode, a 4-channel TIA array, a 4 channel output buffer, control blocks. Maximum channel insertion loss allowed is respectively 1.9dB over 100m of OM3 cables or 1.5dB over 150m of OM4 cable.
