Check Point CPAC-TR-40SR-SSM160-QSFP Compatible 40GBase-SR4 QSFP+ Transceiver (MMF, 850nm, 150m, MTP/MPO, DOM).
The QSFP+ transceiver is probably the most widely-used and most popular 40G transceiver for short distance transmission, mostly link lengths of 100m and 150m on OM3 and OM4 multimode fibers. It is an MPO-interfaced parallel fiber optic transceiver with a 4x10G transmission pattern. The 40GBase-SR4 can achieve simultaneous 40G signal sending and receiving with the help of four 10G SFP+ lanes in one module. You can usually see this type of transceiver being used in data centers to interconnect two switches with 12 lane ribbon cables.
