The 3-port DWDM 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; DWDM has 100GHz, 200GHz and other channel spacing. Compared with CWDM, it greatly increases the number of working wavelengths, thereby greatly increasing the signal transmission speed and communication capacity.
