ADVANTEST Q8347 350 to 1750 nm  Optical Spectrum Analyzer

The Advantest Q8347 Optical Spectrum Analyzer exhibits its full capabilities in evaluation of WDM (wavelength division multiplex) transmission systems, ultra high-speed optical transmission systems and narrow-band optical filters, extending applications for the coming information society. Although higher resolution can be obtained with optical spectrum analyzers using a Fabry-Perot interferometer, they had problems such as narrow measuring spans and low wavelength accuracy. Designed based on improvements on existing spectrum analyzers employing a Fourier spectrum system with a Michelson interferometer, the Q8347 optical spectrum analyzer has attained high wavelength resolution and measurement accuracy. The Advantest Q8347 can achieved a high resolution of 0.01 nm and high accuracy of ± 0.01 nm (1 GHz resolution and ± 1 GHz accuracy in optical frequency display mode) at 1.55 µm band. Signals of optical wavelength division multiplexing (WDM) transmission can be separated for accurate wavelength measurement. In addition, it is powerful for analyzing chirps from laser diodes and Soliton transmission, and for measuring the output of narrow-band filters. At short wavelengths, higher resolution can be obtained. At the 500 nm band, a resolution of 0.001 nm is achieved and this is suitable for analysis of blue laser diodes. Specifications. Measurement range: 0.35 to 1.75 µm. Maximum resolution (High-resolution mode): Approx. 0.01 nm/1.55 µm, Approx. 0.003 nm/0.85 µm. Wavelength Accuracy (High-resolution mode): ± 0.01 nm or less. Wavelength Span 0.01 nm/DIV to 140 nm/DIV. Measurement range (Input sensitivity): -72 to +10 dBm (1.2 to 1.6 µm), -42 to +10 dBm (0.35 to 1.75 µm). Accuracy: ± 1.0 dB (780 nm), ± 0.7 dB (1310 nm, 1550nm) and input level -10 dBm. Measurement time: 1 second 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.

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

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.
