Main parameters of optical transceiver modules

Data rate: Data rate refers to bit number per sec and its main optical transceiver modules are100M, 1000M, 2.5G, 4.25G and 10G.

Transmission distance：Transmission distance can be classified as short, medium and long distance. Short distance refers to those distances below 2km; medium distance refers to those distances from 10~20km and long distance refers to distances over 30km and 40km.

Central wavelength：Central wavelength refers to optical bands used by optical signals. Central wavelength of optical transceiver modules now is mainly classified as 850nm、1310nm、1550nm. As for 850nm, it is more often used in the distance below 2km, while 1310nm and 1550nm are mostly used for medium and long distance, that is to say, it is often used in over 2km.
