Home / Automatic power compensation for fiber optic amplifiers
Automatic Power Control (APC) corrects the power level differences and ensures that power for different channels is according to the target power profile for the spectrum. Optical power loss (attenuation) refers to the reduction of signal strength as light propagates through fiber. Measured in decibels (dB), loss degrades signal quality, limits distance, increases bit-error rate, and escalates infrastructure cost. To reduce the impact of power unevenness, we propose an automatic power optimization (APO) algorithm to guarantee reliable transmission for all channels, especially the channels at short wavelengths. Last lecture we reviewed the different amplifier technologies and basics of optical amplification.
