KOMAKI, Japan -- Santec, a leading design and manufacturer of tunable lasers, optical instruments, OCT products, and fiber-optic components, 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.

The OTF-970 line up consists of two versions depending on transmission bandwidth range and slope shape. The Standard type has 0.1 to 15nm adjustable bandwidth with a filter slope of 200dB/nm, and the ultra-fine type has 0.08 to 4nm bandwidth tuning with our steepest filter slope, 400dB/nm. The fully programmable OTF-970 has automatic adjustment of the filter center wavelength and bandwidth. An integrated power meter monitors output power and features an automatic peak search function.
