BL-CWDM Coarse Wavelength Division Multiplexer
 
CWDM is a low-cost WDM transmission technology for the access layer of the metropolitan area network. It uses the huge bandwidth of the low-loss area of a single-mode fiber to couple light of different wavelengths to a single fiber for transmission. CWDM Coarse Wavelength Division Multiplexer has a wide wavelength interval of 20nm, which has lower requirements for lasers, effectively reduces network operating costs and improves system reliability. It is widely used in telecommunications, radio and television, enterprise networks, campus networks and other fields.
