Product feature
Using laser light which is high purity and low noise.
It's able to measure with a high dynamic range that characteristic of various optical parts and other applied products.
Taking advantage of a low noise.
It's best for noise figure (NF) measurement of the optical fiber amplifier (EDFA etc.), because the RIN characteristic is quite excellent and has no influence to the characteristic of object to be measured.
About RIN:
RIN is an index of the intensity noise that the semiconductor laser is generated, and the one that the ratio of the light intensity noise per the unit frequency (fluctuation of the light intensity) and the average light output was taken. The RIN value will be deteriorated, if getting more noise with the measure at same optical output. It's necessary to lower the noise level that is fluctuation of light by laser source output to make sure to detect the signal by the optical communication.

(RIN: Relative Intensity Noise)
Utilizing the narrowness linewidth and the short-term frequency stability.
It is the best for the measurement that uses an optical beat, because the Spectrum linewidth is very narrow which is 50kHz or less, and the frequency is steady.
* About spectrum linewidth:
It shows the wavelength spread, and the narrower linewidth is, the higher single wavelength state is. In the laser, fluctuation of oscillation frequency by various changes is a Spectrum linewidth. It is necessary to control the Spectrum linewidth that is a time fluctuation of the laser oscillation spectrum in the optical communication because of the decrease of it of the noise characteristic when the signal is transmitted.

* The spectrum has the frequency extension twice actual measurement light for the measurement by the delay self-heterodyning technique. Therefore, the value of the stroke width becomes 1/2 of the display values.
Customizing for your usage.
- It is possible to customize as you like.
- Changing range of tunable wavelength.
- Changing the maximum value of power.
- Cutting price by removing the attenuator, if unnecessary.
- Adding in such as the fiber amplifiers for the high-power.
- Please inquire in detail.
Usage example
High measurement of dynamic range with PC can achieve, but spectrum analyzer can't.
- GP-IB interface provides the coordinated measurement with PC and with power meter.
- It's able to measure modules (etc.) with a high dynamic range, but isn't able by the spectrum analyzer.
- We can offer sample program, so please contact us in detail.
Evaluation of optical communication transmission experiment with polarization dependent.
It's possible to use as the evaluation of the optical communication transmission experiment etc, because the polarization extinction ratio is 20dB or more, and the polarization stability is high.
As a light source for the fiber sensor.
It's the best as a light source for the fiber sensor because of a low noise, narrow linewidth and high stability.
