ADN8820 is a programmable laser driver and controller in the ADN series with four operating modes: constant laser current, constant optical output power, constant EDFA gain and constant laser power. High power efficiency: >90%
The ADN8820 is a continuous wave (CW) and Erbium-Doped Fiber Amplifier (EDFA) laser diode driver and controller designed for telecommunication systems. It provides low noise and precise current control, supporting four operational modes: Constant Current (CC), Constant Laser Power (CLP), Constant Output Power (COP), and Constant EDFA Gain (CG). The device supports both common-cathode-to-ground and common-anode-to-VDD configurations.
