Dense Wavelength Division Multiplexing (DWDM) is a Wave division multiplexing (WDM) technology that extends the transmission capacity of existing optical fiber networks. It multiplexes multiple optical carrier signals into a single fiber for transmission, which can save a lot of fiber resources in long-distance transmission applications. #fibertransceiver #opticalswitch #wdmmodule#0TS3000DWDM

CWDM is a low cost WDM transmission technology for metro area network access layer. In principle, CWDM uses optical multiplexers to multiplex optical signals of different wavelengths into a single fiber for transmission. At the receiving end of the link, the mixed signals in the fiber are decomposed into signals of different wavelengths with the aid of optical demultiplexers and connected to the corresponding receiving equipment. #wdmmodule # wdmdevice
