■ 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.
