We provide filter-based wavelength devision multiplexing (WDM) filter devices that are customized to the particular wavelength bands for your special applications.
Filter WDM module is based on Thin Film Filter (TFF) technology. The Filter-Based WDM is extensively used in EDFA, Raman amplifiers, WDM networks and fiber optics instrumentation. The FWDM series is based on environmentally stable Thin Film Filters technology. The device combines or separates light at different wavelengths in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability.
Our Filter-Based WDM product family covers following wavelength windows commonly used in optical fiber systems: 1310/1550nm (for WDM or DWDM optical communications), 1480/1550nm (for high-power DWDM optical amplifier/EDFA), 1510/1550nm (for DWDM multi-channel optical networks) and 980/1550nm (for high performance DWDM optical amplifier/EDFA) and 1310/1490/1550nm (for PON/FTTX/test instrument)
