Overview
DATE OF DISCONTINUANCE: April 2007


The MS9020D is a handy optical measuring instrument that incorporates an LD or an LED light source and an optical power meter. It can also be used for return loss measurement. Every unit of the LD light source (4 types), LED source (7 types), the sensors (8 types) and the return loss measurement unit (1 type) is a plug in type, for easy exchange and highest suitability for field use.

The MS9020D covers 0.66 µm, 0.85 µm, 1.3 µm, and 1.55 µm bands for optical loss measurement. In addition to the CW mode, it provides a modulated light mode with 270 Hz, 1 kHz, and 2 kHz modulation signals. Therefore, it is possible to measure optical loss over a wide dynamic range without stray light effect. This is the most suitable for single mode fiber measurement. For return loss, 1.3 µm band single mode fibers can be measured in the 0 to 40 dB range. As a power meter, every sensor has a wavelength calibration function of 5 nm steps at 3 wavelengths, so absolute values can be read directly.

  • Measures optical loss up to 67 dB
  • Measures CW and modulated light
  • Provides calibration function of 5 NM steps at 3 wavelengths
  • Also measures optical return loss (0 to 40 dB)
  • Operates in 3 modes; AC, rechargeable battery, and dry cells
  • Various Connectors

  • Optical fiber loss measurement
    When measuring optical fibers, it is convenient to provide one MS9020D each at both the near and far ends. By using switchable light source units (MS0904A/B, MS0909A), one touch measurement of 0.85/1.3 µm and 1.3/1.55 µm can be done. More accurate loss measurement is possible by using the modulated light function. When an LD light source is used, it is possible to measure optical loss up to 67 dB.


  • Optical parts performance check
    A light source and optical power meter are provided, and an optical parts performance check is possible at low cost.

  • Optical return loss measurement
    Return loss of connectors or optical devices can be measured easily using return loss measuring units.
