ADN8820 - EDFA and CW Laser Controller

General Description

The ADN8820 is a versatile Continuous Wave (CW) and EDFA laser diode driver and controller.

It provides a low noise and precise current control for driving a source or pump laser diode.

Key Features

  • Four Operational Modes Including: Constant Laser Current Constant Optical Output Power Constant EDFA Gain Constant Laser Power High Power Efficiency: >90% Three Built-In Photodiode TIAs Adjustable Laser Diode and EDFA Protection Limits Free-run or Synchronous Switching Frequency Modes Adjustable Phase Delay for Synchornous Clock Mode Optional Dithering Built-In Programmable Dither Frequency and Amplitude ADN8820.
  • Output Power (COP), or Constant EDFA Gain (CG). Multiple pump laser applicatio.
