LGX CWDM Module: 4CH Optical CWDM LGX Module, LC/ PC Plug-in Metal BOX
CWDM is a low-cost WDM transmission technology for the access layer of the city network. In principle, CWDM is the use of optical multi-selectors to reuse optical signals of different wavelengths to a single fiber for transmission, in the receiving end of the link, with the help of optical complexes to break down the mixed signals in the fiber into different wavelengths of signal, connected to the corresponding receiving equipment.
