ADVANTEST Q7606B Optical Chirpform Test Set

The Advantest Q7606B Optical Chirpform Test Set is a lightwave modulation test set, used together with a digital sampling oscilloscope, to separately measure and evaluate the chirp (frequency-modulated / FM) and intensity-modulated (IM) components of incident laser light. The Q7606B contains two sets of fiber-type Mach-Zehnder interferometers and their control circuits. The Q7606B can selectively output the sum of, or difference between the frequency-modulated / FM and IM components of the modulated incident light by switching the measurement mode. The sum (IM+FM) and difference (lM-FM) data are processed by the digital sampling oscilloscope and the personal computer to separate the chirp FM and IM components from each other, thus making it possible to evaluate the time-domain charactenstics. Specifications. Wavelength measurement range: 1510 to 1590 nm. Optical input power range: -20 to 10 dBm. Free Spectral Range: 150 GHz ±15 GHz.

*This is a Web introductory price for one calibration of the ADVANTEST Q7606B. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

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
