 Programmable Optical Tunable Filter OTF-930
|
The OTF-930 bench-top type tunable filter has wide variety of filter profile options with combining filter type and number of cascaded filters (S1,S2,S3) to suit most fiber optic applications. It features full 80 nm improved tuning mechanics and improved low insertion loss. Low PDL and low PMD are also characteristic of Santec "linear sliding" filters.
OTF-930 equips GPIB and RS-232C control interface which enables remote control and data acquisition.
