Optical Tunable Filter
OTF-930
The OTF-930 is a polarization independent 80nm tunable filter. Santec's unique "Linear Sliding" technology enables precise, continuous wavelength tuning with constant optical properties such as PDL, bandwidth and insertion loss. A breakthrough in filter design enables this device to achieve a very low insertion loss. The instrument is designed to allow filters to be cascaded to increase filter isolation with minimal increase in insertion loss. A wide selection of filters is available to suit most fiber optic applications.

Applications
ASE Noise Suppression
When optical signals are amplified using EDFAs, unwanted levels of amplified spontaneous emission (ASE) can decrease the signal-to-noise ratio. The OTF-930 with 08-S1, 08-S2 or 12-S2 filters can remove the ASE noise with minimal loss.
Wavelength Channel Selection
The 03-S2 filter configuration is particularly suitable for selecting a single DWDM wavelength from a 100GHz grid. Other filters can be used to select other ITU grid spaced signals.
Incoherent Light Source
When used in combination with a broadband light source the OTF-930 can be configured as a tunable light source. Although the output power is relatively low (-30 to -20dBm) the incoherent light is especially useful for applications which are affected by coherent resonance effects or non-linear interference.
