40G QSFP+ SR4 ( [ Ссылка ] ) optical transceiver is a four-channel small pluggable optical module. Its transmission rate can reach 40Gbps and the maximum transmission distance is 150m. 40GBASE-SR4 QSFP+ optical module has 12-Fiber MTP/MPO interfaces and usually connects with MTP/MPO multimode fiber patch cables with a wavelength of about 850 nm. The QSFP-SR4-40G optical module uses VCSEL transmitter type, which is ideal for applications such as parallel optical transmission and parallel optical interconnects, and is highly cost-effective.
