ADVANTEST Q8163 Polarization Scrambler

The Advantest Q8163 Optical Polarization Scrambler uses Advantest’s original polarization-variance method. By adopting the high-speed optical-fiber polarization scramble unit, Q8163 achieves: High-speed polarization variance. Low fluctuation of insertion loss. Low insertion loss. High reliability. Fast and ensured measurement of polarization dependent loss (PDL) can be made by using it with Q8221 series optical power meter, which offers low polarization dependency, high-speed measurement and the LD light source. Specifications. Wavelength range: 1.29 to 1.58 µm. Insertion loss: <= 3 dB or less. Insertion-loss fluctuation: ± 0.005 dB or less. Return loss: >= 43 dB (47 dB typical). Polarization-variance speed (two modes available): >= 500 rotations of the Poincaré sphere per second (high speed), >= 10 rotations of the Poincaré sphere per second (low speed). Input/output connector: FC-SPC. External control: GPIB equipped as standard.

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 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
