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.

dBm
Optical power referenced to 1 millimatt

Multimode Fiber
Multimode Fiber has a large core (almost always 62.5 microns - a micron is one one millionth of a meter - but sometimes 50 microns) and is used with LED sources at wavelengths of 850 and 1300 nm for short distance, lower speed networks like LANs. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Refractive Index
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium. The velocity at which light travels in vacuum is a physical constant, and the fastest speed at which energy or information can be transferred. However, light travels slower through any given material, or medium, that is not vacuum.

Total insertion loss
A measure of the loss of light within an optical component
