   ADVANTEST Q8331   Description / Specification:    
ADVANTEST Q8331 1270 to 1680 nm Multi Wavelength Meter

The Advantest Q8331 Multi Wavelength Meter uses a He-Ne laser as wavelength reference enables high accuracy measurements of up to ±1 ppm ±1.5 pm at 1550 nm). In addition, since the He-Ne laser oscillates with very high stability, ±1 ppm measurement accuracy is guaranteed over a long time period without recalibration. The Q8331 can measure wavelengths at a sampling speed of 2 measurements per second so that wavelength fluctuations caused by temperature variations can be captured precisely. The Michelson interference method allows for measurements with high resolution of up to 0.1 pm/10 MHz. The Q8331 includes a temperature and atmospheric pressure sensor, that allow it to automatically adjust measurements to changes in temperature and atmospheric pressure. The Q8331 can be switched to display optical frequency or wavelength. This is convenient for adjusting input wavelengths to the ITU-T grid. Since the deviation is displayed with reference to the keyed user entry, wavelength fluctuations of the input optical signals caused by temperature variations can be viewed with high resolution and high precision.

Amplified Spontaneous Emission Source (ASE)
ASE, a process where spontaneously emitted radiation (luminescence) is amplified. In lasers and particularly in high-gain erbium-doped amplifiers, amplified spontaneous emission is usually an unwanted effect. It tends to limit the gain achievable in a single stage of a fiber optic amplifier to the order of 40–50 dB.

Dynamic Range
In a transmission system, the ratio of the overload level to the noise level of the system, usually expressed in dB. Ratio of the highest to lowest detectable signal of a system, expressed in dB.

Optical Power
Optical Power is usually measured in "dBm", or decibels referenced to one miliwatt of power. while loss is a relative reading, optical power is an absolute measurement, referenced to standards. You measure absolute power to test transmitters or receivers and relative power to test loss.

Relative Wavelength Accuracy
When randomly changing the wavelength and measuring the differences between the actual and displayed wavelengths, the relative wavelength accuracy is ± half the span between the maximum and the minimum value of all differences.

Wavelength
Wavelength is a term for the color of light, usually expressed in nanometers (nm) or microns (m). In Fiber Optics the wavelenghts mostly used are in the infrared region where the light is invisible to the human eye.
