    Boston Applied Technologies' EquinoxTM Variable Gain Tilt Filter (VGTF) is designed for dynamically compensating the gain tilt profile in Erbium Doped Fiber Amplifiers (EDFAs) and power tilt in multi-channel wavelength division multiplexing (WDM) systems. Based on OptoCeramic® technology, VGTF enables dynamically flattening or tilting the broadband signal in a real-time fashion. BATI's VGTF contains no moving parts and offers high speed, low insertion loss, low polarization dependence loss (PDL), and a wide dynamic range. BATI's advanced micro-optical design also enables the integration of the static gain flattening filter (GFF) and other components into one compact and robust package for space and cost savings and performance enhancement. Also available are Slope VOAs and Slope Adjustabe Filters.
