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 .

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.
