ADVANTEST Q8381A 350 to 1750 nm  Optical Spectrum Analyzer

The Advantest Q8381A optical spectrum analyzer can analyze a wide wavelength band from 350 to 1750 nm and a wide dynamic range from -85 to + 10 dBm (1.1 to 1.6 um), accommodating measurements on display LEDs and optical devices for communication. In addition, Advantest's unique technology realizes low polarization dependence and a high level measurement accuracy of ± 1.5 dB. In addition to the automatic optimum measurement condition setting, automatic peak search and half- value width measurement functions , the Q8381A mounts the pulse light measuring function, power monitoring function and luminosity compensation display functions for improvement of operation and analysis capabilities. In conventional pulse light measurement, even if a number of averagings is made and the average power of duty ratio is obtained; low level and data missing may result. The Q8381A can measure a wide wavelength range from 1.1 to 1.6 um at a high sensitivity of -85 dBm. Therefore, level measurement for spontaneous emission light from an erbium doped fib er amplifier (EDFA) and wavelength characteristic measurement in combination with white light source can be performed over a wide dynamic range. Specifications. Measurement range: 0.35 to 1.75 um. Resolution: 0.1 , 0.2, 0.5, 1.0, 2.0, 5.0 nm. Accuracy: ± 0.5 nm (23 ± 5 C), 1.0 nm (10 to 40 C). Repeatability: 0.1 nm or less (during one-minute repetitive sweep). Measurement range (input sensistivity): -75 to +10 dBm (0.7 to 1.6 um). Level Accuracy: ± 1.5 dB or less (at wavelength of 0.633, 1.31, and 1.55 um). Linearity: ±0.5 dB/ 20 dB or less, ±1.0 dB/ 40 dB or less. Scale: 0.2, 0.5, 1.0, 2.0, 5.0, 10.0 dB/DIVand linear. Measurement time: 0.8 sec or less (with a span of 200 nm or less), 1.5 sec or less (with a span of 500 nm or less).

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
