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.
