Optical Light Source

Optical Light Source / Optical Power Meter with Calibration Cert


ALK2001 is Samudra Communication’s new-type light source. It provides single to quad-wave length output including  650nm visible light source and 850/1300nm wavelength for multi-mode fiber or 1310/1550nm dual-wavelength for single-mode fiber. Together with a new type of power meter, they combine the accurate test solution for the optical fiber networks.


  1. Uncertainty is a total difference between two measurement results that were tested by a Power Meter and another Standard Power Meter respectively.
  2. Wavelength Range is the specified standard operating wavelength range in which the Power Meter can work properly under certain technical specifications.
  3. Power Measurement Range is the maximum and minimum range in which the Power Meter can work properly.
