Center wavelength adjustment & bandwidth tuning Independently

Santec has developed a new programmable optical tunable filter (OTF-970) that combines the attractive features of wide C+L band tunability with of bandwidth tuning and sharp filter slope. Built with novel, free-space custom optics and an ultra-fine tuning mechanism the OTF-970 ensures precise filter control and a flat-top passband shape. The filter is particularly suited to high isolation channel selection and noise filtering in high-speed transmission testing at 40Gb/s and 100Gb/s.
