Optosun Filter-based WDM products use Thin Film Filter technology, or TFF.

When compared with fused WDM technology, we see that filter devices generally, work more efficiently across a wider bandwidth, have much lower insertion losses, possess greater power handling capabilities and higher isolation properties.

Filter WDM devices combine or separate light at different wavelengths across a wide wavelength range. This technology provides a very low insertion loss, with low polarization dependence. It also offers high isolation and excellent environmental stability properties.
