Mechanical Dimensions (Unit: mm)
ETERN three-port FWDM 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. The difference between FWDM and CWDM is that FWDM can multiplex or de-multiplex two or more optical signals of different wavelengths in a single wide wavelength range channel, as well as increasing signal transmission speed and communication capacity. FWDM device is widely used in telecommunications, radio and television, enterprise network, campus network and other fields
