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.
There are three versions available with different transmission bandwidth and slope shape with the ultrafine-plus(0.05 to 3nm bandwidth) having the steepest filter slope (1000 dB/nm). 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 users to have full remote control and measurement automation. The OTF-980 is controlled via the front panel touchscreen.
