Dense wavelength division multiplexers (DWDM) combine (or separate) 100 GHz–spaced narrow band optical signals of ITU-standardized optical wavelengths. The interference filter technology is used to achieve low loss and high channel isolation properties. All element devices have epoxy-free optical paths.
Features:
High channel isolation
High reliability
