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).

Chromatic Dispersion
Chromatic Dispersion is a broadening of the input signal as it travels down the length of the fiber. Chromatic Dispersion results from a variation in propagation delay with wavelength, and is affected by fiber materials and dimensions.

Detector
A Detector is a signal conversion device that converts power from one form to another, such as from optical power to electrical power

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Polarization Mode Dispersion (PMD)
Polarization mode dispersion (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical pulses. It is he difference between the maximum and minimum values of loss typically measured in ps/km^1/2.
