Wavelength&Bandwidth Tunable Filter OTF-970

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.

Overview

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. The setting of wavelength and the bandwidth can be automated and be operated remotely by the GPIB interface.
