Products > Equinox™>VGTF

Boston Applied Technologies' 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 OptoCeramicTM 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, cost saving and performance enhancement.
