■ By using laser beam with high purity and low noise

Spectral characteristics of optical components or other applied products can be measured with high dynamic range.

■ Taking advantage of low noise

Since the RIN characteristic is very good and does not affect the characteristics of the object under test, it is ideal as a light source for measuring the noise figure (NF) of optical fiber amplifiers (EDFA, etc.).

■Taking advantages of narrow spectrum linewidth and high short-term frequency stability

The spectrum linewidth is very narrow, less than 50 kHz, and the frequency is stable, which makes it ideal for measurement using optical beats.


■High dynamic range measurement that cannot be achieved with a spectrum analyzer

  • The GP-IB interface makes it easy to perform measurements in conjunction with a PC or a power meter.
  • It can measure optical modules, etc. with a high dynamic range that cannot be achieved with a spectrum analyzer.

■Evaluation of polarization-dependent optical communication transmission experiments
Evaluation of polarization-dependent optical communication transmission experiments.
The polarization extinction ratio of 20dB or higher and high polarization stability can be used for evaluation of optical communication transmission experiments.

■ As a light source for optical fiber sensing

The excellent optical characteristics of low noise, narrow linewidth, and high stability make it ideal as a light source for optical fiber sensing.
