KEYSIGHT N7788B Optical Component Analyzer

The Keysight N7788B Optical Component Analyzer's proprietary technology is comparable with the well-known Jones-Matrix-Eigen analysis (JME) which is the standard method for measuring polarization mode dispersion (PMD) or differential group delay (DGD) of optical devices. For spectral measurements of polarization dependent loss and dispersion, the N7788B is combined with a Keysight swept-wavelength tunable laser, such as the 81600B or 81960A (not included) and the Polarization Navigator software application for single-scan measurements.

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
