The 3-port CWDM device is mainly used for passive wavelength division multiplexing modules. It is a TFF (thin film filter)-based wavelength division multiplexing technology. It has a variety of package sizes and optional wavelengths. It is composed of common (COM) and transmission It is composed of three ports: Pass and Reflect; the wavelength range complies with the ITU-I G.695 standard.
