The overall structure of the DWDM system mainly includes:
1、Optical wavelength conversion unit (OTU); OTU transponder can be used for wavelength conversion, relay amplification and signal regeneration.
2、Wavelength division multiplexer: divided into demultiplexer/multiplexer (ODU/OMU);
3、Optical amplifier (BA/LA/PA); includes line amplifier, power amplifier and pre-amplifier.
4、Dispersion compensation unit (DCM);
Therefore, when designing a DWDM solution, the series of WDM service cards mentioned above will be used to transmit data and enhance optical signals most effectively.
