The OTF-980 is a versatile programmable optical tunable filter that allows simultaneous and independent tuning of center wavelength and bandwidth over C & L bands. The OTF-980 is built with novel free-space optics combined with an ultra-fine tuning mechanism to ensure precise filter control and a flat-top passband shape. Three versions are available depending on transmission bandwidth range and slope shape. Among them, the Ultrafine-Plus has 0.05-3nm bandwidth tuning with our steepest filter slope, 1000dB/nm. The fully programmable OTF-980 has automatic adjustment of the filter center wavelength and bandwidth. An integrated power meter monitors power at the output and features an automatic peak search function. GPIB, Ethernet and USB interfaces with the industry standard SCPI command set allows full remote control and measurement automation. The OTF-980 is also controlled via the front panel touchscreen.
