Figure 43. OADM Using the AD5383 as Part of an Optical Attenuator
OPTICAL ATTENUATORS
Based on its high channel count, high resolution, monotonic
behavior, and high level of integration, the AD5383 is ideally
targeted at optical attenuation applications used in dynamic
gain equalizers, variable optical attenuators (VOA), and optical
add-drop multiplexers (OADM). In these applications, each
wavelength is individually extracted using an arrayed wave
guide; its power is monitored using a photodiode, transimped-
ance amplifier and ADC in a closed-loop control system. The
AD5383 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.
