The 40G SR4 optical module is an optical module with a transmission rate of 40G, 4-channel short-distance transmission, and packaged as QSFP +. At present, 40G QSFP + optical modules have many advantages and are widely used in various optical networks.
QSFP + is a 40G optical module packaging form defined by the IEEE organization, which greatly meets the market demand for high density and high speed. The 40GQSFP + optical module is a compact hot-pluggable optical module. It has four transmission channels, and the data rate of each channel is 10Gbps.
This optical module conforms to various standards such as SCSI, 40G Ethernet, and 20G / 40G Infiniband. And 40G QSFP + optical modules have multiple types, and SR4 is one of them.
40GBASE-SR4 optical module adopts MTP / MPO interface, the working wavelength is 850nm, and is generally used in multimode applications. When it is used with OM3 / OM4 multimode optical fiber, the transmission distance is 100 m and 150 m respectively, which is mainly used to realize the connection between network devices in the data center.
The 40GBASE-SR4 optical module can not only use MTP / MPO fiber jumpers to connect two 40G network devices, but also can be used with MTP / MPO to LC fiber jumpers to achieve the connection between 40G network devices and 10G network devices.
