Filter-based WDM Device (FWDM)
The filter wavelength division multiplexer(FWDM) series are based on environmentally stable thin film filters technology. The devices combine or separate light at different wavelength in a wide wavelength range.
They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. These components have extensively used in EDFAs, Raman amplifier, fiber sensor system, WDM networks and fiber optics instrumentation.
