The Santec OTF-910 is a precision optical tunable filter that selects and controls specific wavelengths across the C-band and L-band spectrum. Built on interference filter technology, it delivers wavelength-independent performance for spectral shaping, channel simulation, and noise filtering in optical communications and test systems. Full GPIB control enables integration into automated measurement setups. Optional ATT provides built-in attenuation with manual or feedback-loop control. Optional APC connectors minimize back reflection.
