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.

Coherence Length
Average distance over which superimposed waves lose their phase relationships

Linewidth
Linewidth is the width of a spectral line in terms of wavelength, wave number and frequency.

Power Flatness Versus Wavelength
When changing the wavelength at constant power setting and recording the differences between actual and displayed power levels, the power flatness is ± half the span (in dB) between the maximum and the minimum of the measured power levels.

Spectral Width
Spectral Width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical communications applications, the usual method of specifying spectral width is the full width at half maximum. This is the same convention used in bandwidth, defined as the frequency range where power drops by less than half (at most -3 dB).

Telecom Bands
Optical fiber communications typically operate in a wavelength region corresponding to one of the following Bands. O Band (original): 1260–1360 nm. E Band (extended): 1360–1460 nm. S Band (short wavelengths): 1460–1530 nm. C Band (conventional): 1530–1565 nm. L Band (long wavelengths): 1565–1625 nm. U Band (ultralong wavelengths): 1625–1675 nm
