Coarse Wave Reuse Filter CWDM
CWDM transmits multiple wavelengths in one fiber, spanning 1270-1610 at 20nm intervals, with up to 16 different wavelengths. A key broadband wavelength-division component, it uses dielectric-film filters for stable wavelengths and sealed packaging for environmental stability. CWDM reduces fiber use and network cost, addressing fiber shortage and transparent multiservice transmission. Primarily used in metropolitan aggregation/access layers, it enables rapid deployment and service launch. Low cost, low power and compact size make it an economical, high-performance solution widely used in metropolitan transmission.
