SFP lc multimode 2.5G 80km SMF 1550Tx/1490nmRx module
Because the optical fiber itself has dispersion, loss and other side effects on the optical signal. Therefore, different types of light source can transmit different distances. When docking optical interface, optical module and optical fiber should be selected according to the farthest signal transmission distance. The transmission distance of optical module can be divided into short distance, medium distance and long distance. Generally speaking, 2km and below are short distance, 10-20km are medium distance, 30km, 40km and above are long distance.
Transmission rate refers to the number of bits (bits) of data transmitted per second. The transmission rate is as low as 100 Gbps. Optical modules are divided into 155m / 622m / 1.25g/2.125g/4.25g/8g/10g. The most commonly used optical modules in the market are 155mbps, 1.25gbps, 2.5Gbps and 10Gbps. In optical fiber storage system, optical modules also have 2gbps, 4gbps and 8gbps. The SFP optical module supports Gigabit Ethernet, SONET, fibre channel and other communication standards.
