Boston Applied Technologies' Dynamic Gain Flattening Filter (DGFF) is
designed for dynamically gain curve reshaping over the whole band in Erbium
Doped Fiber Amplifiers (EDFAs) and power tilt in multi-channel wavelength
division multiplexing (WDM) systems. Based on OptoCeramicTM
technology, DGFF enables dynamically flattening or tilting the broadband
signal in a real-time fashion. BATi's DGFF contains no moving parts and
offers high speed, low insertion loss, low polarization dependence loss
(PDL), and a wide dynamic range. BATi's DGFF has multi sinusoidal filters.
Each sinusoidal filter is a building block that has harmonic frequencies,
variable amplitude and variable phase. The combination of multi stages
with real time control can form any smooth curve represented by sum of
Fourier curves. It has compact and robust package for space, cost saving
and performance enhancement.
