Single Channel DWDM 100G/200G
Single Channel three-port DWDM device is mainly used in passive wavelength division multiplexing module. It is a kind of wavelength division multiplexing technology based on TFF (thin film filter). It has a variety of package sizes and wavelength options. It consists of three ports: COM, Pass and Reflect.
Compared with CWDM, DWDM has 100 GHz, 200 GHz channel spacing, which greatly increases the number of working wavelength, thus greatly increases the signal transmission speed and communication capacity. It is suitable for long-distance, large-capacity trunk network, or ultra-large capacity MAN core nodes, and is widely used in telecommunications, radio and television, 5G and other fields
Features:
— Low polarization dependent loss
— Low insertion loss
— High channel isolation, completely passive
— Exceptional reliability and stability
Application:
— Metro WDM systems
— Access Networks, Long haul WDM systems
— Enterprise Network
