TFF Type WDM T&S TFF WDM is based on Thin Film Filter (TFF) technology. Our Filter-Based WDM product family covers following wavelength windows commonly used in optical fibre systems: 1310/1490/1550nm (for FWDM Device), 1271~1611nm (for CWDM Device or Module), 1525~1565nm (C_band for ...
Thin film filter technology is one solution for addressing these design concerns. Their high-accuracy fabrication process provides excellent repeatability, and ceramic substrates make for rugged construction and easy reflow onto existing PWBs. Some ceramic substrates exhibit high Dkcharacteristics, enabling v...

Given its low cost and high reliability, it is not surprising that thin-film-filter technology has come to dominate the 200- and 100-GHz dense-wavelength-division-multiplexing (DWDM) markets.1Competing solutions such as arrayed-waveguide-grating (AWG) and fiber-Bragg-grating (FBG) technologies h...
Thin-film reflective designs have greater flexibility in their phase response compared to thin-film transmissive designs. In transmission, a TFF is a minimum-phase infinite impulse response (IIR) filter3. IIR filters are limited by basic principles of causality and stability, such that the amplitude...
