OPTICAL ATTENUATORS

Based on its high channel count, high resolution, monotonic

behavior, and high level of integration, the AD5384 is ideally

targeted at optical attenuation applications used in dynamic

gain equalizers, variable optical attenuators (VOA), and optical

add-drop multiplexers (OADMs). In these applications, each

wavelength is individually extracted using an arrayed wave

guide; its power is monitored using a photodiode, transimped-

ance amplifier, and an ADC in a closed-loop control system.

The AD5384 controls the optical attenuator for each

wavelength, ensuring that the power is equalized in all

wavelengths before being multiplexed onto the fiber. This

prevents information loss and saturation from occurring at

amplification stages further along the fiber.
