Reachoptics' CWDM (Coarse Wavelength Division Multiplexing) is a standardized WDM technology that uses up to 20 different wavelengths for data transmission over a single fiber. In contrast to Dense WDM (DWDM), CWDM uses only a ‘coarse’ wavelength grid, so the underlying optical component technology is simpler. This makes CWDM systems very cost-effective, but also limits them in terms of total capacity.
Reachoptics produce for 2CH/4CH/8CH/10CH/16CH/18CH CWDM Mux Demux,all could with four package type, Stainless Steel Tube,ABS Box Package,LGX Box Package,19inch Rack Mount Package. And also it could be with Single Fiber or Dual Fiber Optical Transmitted.
