ATN-HP: Variable Optical Attenuator
The ATN module integrates industry standard attenuator components. It combines a 60 dB attenuation range and operates throughout a large wavelength range.
As part of a test set, ATN modules can be used to equalize channels and to reach low power levels without modifying sources’ signal-to-noise ratio. This is especially useful for optical amplifier characterization. The ability to receive up to 2 W input power allows to use this on large counts DWDM test bench.
