Abstract
An optical amplifier control system provides real-time control of an optical amplifier in response to an analog signal having a large dynamic range. The optical amplifier control system uses a non-linear analog-to-digital converter, such as a logarithmic-scale analog-to-digital converter to achieve low relative quantization error. The amplifier control system may also use multiple analog-to-digital converters.
