The DMF310C tunable optical filter is a high performance, electronically tunable Fabry- Perot filter designed for channel selection in DWDM communication systems with channel spacings from 50GHz. Packaging technology protects the filter from humidity and other environmental effects to ensure long life with high wavelength and insertion loss stability.

A sophisticated capacitance bridge servo system stabilizes the transmitted wavelength and ensures linear and repeatable wavelength tuning throughout product lifetime.
