Features
■Wide dynamic range
KLS-201A series guarantee an accurate measurement of optical devices with its extraordinary wide dynamic range.
■Low noise
KLS-201A sereis is best suitable for noise figure (NF) measurement of the optical fiber amplifier: EDFA, etc. The excellent RIN (Relative Intensity Noise) characteristics ensures accurate measurement without affecting the characteristics of measuring object.
■Narrow spectrum linewidth
Spectrum linewidth indicates the distribution of wavelength, and the narrower the spectrum line-width, the higher the wavelength isolation. Variation of the oscillation frequency affects the optical spectrum linewidth.
* As for our tunable laser light source, a band pass filter is used in an optical wavelength variable mechanism, and it has capabilities of creating a high-level narrow optical spectrum linewidth with excellent monochromatic and the high stability level over a short period of time.
Applications
■Mearsurement of the optical components and equipments
・Our tunable laser has GP-IB, and it measures coordination between PC and Power Meter.
