OTF-930 Optical Tunable Filter - Santec - #1

Text version of the page

SANTEC OPTICAL INSTRUMENTS Features Applications 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. 80nm tuning range Low insertion loss Low PDL (<0.1dB) & PMD (<0.1ps) over whole tuning range 0.01nm resolution Full GPIB support 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.
