With the rapid development of date service , transmisson networks require higher bandwidth. Traditional PDH and SDH technology , using a single wavelength transfer optical  signal  , which is a great waste of fiber capacity , because the bandwidth of fiber in terms of  the relative to the current use of single wavelength channel is almost unlimited.The technology of DWDM (Dense Wavelength Division Multiplexing ) was born in this context . It not only greatly increases the capacity of the network , but also makes full use of bandwidth  resources of optical fiber and reduces the waste of network resources .  Now , the C band : 1525~1565nm, has been using, the L band :1570~1620nm and the S band:1400nm was being developed.As for the technology of DWDM, people put forward the CWDM (Coarse Wavelength Division Multiplexing). The results obviously show that CWDM network has cost advantage for it is suitable for short distance transport of small networks . In addition, CWDM inherits the advantages of the wavelength division multiplexing system, so that the type network has a certain scale of application in the market. CWDM wavelength interval is 20nm+6.5nm and the wavelength interval is relatively dense, while DWDM wavelength interval is between 0.2~1.6nm with more wave channel number, which has a larger capacity ， supporting EDFA light amplification and transmission distance.
