The 3-Port DWDM device is mainly used for wireless backhaul modules. It is a type of TFF (thin-film filter) wavelength division multiplexing technology, featuring multiple packaging sizes and customizable wavelengths. It consists of three ports: common (COM), pass, and reflect. DWDM has 100GHz and 200GHz channel spacing, which significantly increases the working wavelength range compared to CWDM, thereby greatly enhancing signal transmission speed and communication capacity. It is suitable for long-distance networks, large-capacity metropolitan area networks, or ultra-large capacity metropolitan core nodes. It can also be applied to 5G, metropolitan networks, backbone networks, data centers, and other fields.
