ADVANTEST Q8344A 350 to 1750 nm  Optical Spectrum Analyzer

The Advantest Q8344A is an optical spectrum analyzer with a wide wavelength range from 0.35 to 1.75 um. The usage of a Fourier spectrum system using a Michelson interferometer makes it possible to analyze coherence that cannot be obtained by the dispersing spectrum systems using monochromators. It exhibits its capabilities for evaluation of laser diodes for CDs and video disks. The built-in He-Ne laser used as the reference wavelength realizes a wavelength accuracy of ± 0.1 nm (1.3 um), ensuring a long-term measurement stability even without wavelength calibration. The Q8344A provides a maximum wavelength resolution of 0.05 nm (at 0.85 um), accommodating measurements of laser diodes with narrow mode intervals. The measurement speed is approx. 1.5 seconds (at 0.4 to 1.05 um and 0.8 to 1. 75 um) regardless of the analysis span, allowing it to be used as a system component. With the versatile display, analysis and processing functions , the Q8344A can be used for characteristic measurement applications for diverse components ranging from photo emitting elements such as laser diodes and LEDs to optical components such as optical fibers and filters .

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
