Home / What do ACC and APC mean in optical amplifiers
The EDFAs have both ACC mode ‒ automatic current control or constant current control and APC mode ‒ automatic power control settable via GUI. In the ACC mode, the pump laser's current is set by the user and automatically locked by the EDFA to achieve a constant pumping. This compensation ensures stable optical power levels despite changes in span loss. An optical amplifier is a device which receives some input signal light and generates an output signal with higher optical power. Typically, inputs and outputs are laser beams (very rarely other types of light beams), either propagating as Gaussian beams in free space or in a fiber. From the Factory Floor: We often suggest APC for single-channel links or when you are connecting directly to sensitive equipment that can't handle power surges. Agiltron Erbium-doped fiber amplifier (EDFA) provides cost-effective solutions for high-power optical amplification.
