Keysight (Agilent) N7786B Polarization Synthesizer

The Agilent N7786B Polarization Synthesizer contains a high-speed Lithium-Niobate based polarization controller and a polarization analyzer plus a microcontroller-based driving circuitry. As a polarization stabilizer, it provides a stable output state of polarization (SOP) even with fluctuations and drifts of the input SOP. The stabilized output signal is guided in a standard single-mode fiber (SMF). As an SOP switch, the N7786B cycles through a sequence of SOPs with a speed of more than 40 KHz, which corresponds to a cycle time of less than 25 microseconds. The sequence of SOPs can easily be defined by the user using Stokes coefficients. Specifications. Specification Wavelength range: 1270 nm to 1375 nm, 1460 nm to 1620 nm (Opt 400, O/C/L-Band), 1460 nm to 1620 nm (Opt 500, C/L-Band). Operating wavelength range: 1260 nm to 1640 nm. SOP switching time (non deterministic): < 10 µs. SOP cycling time: < 25 µs. Remaining SOP error after deterministic SOP setting (typical): < 3° at input SOP movement rate of 1.2 rad/s, < 6.5° at input SOP movement rate of 40 rad/s. SOP uncertainty (typical): 1.5°. DOP uncertainty: ± 2.0%. DOP uncertainty after user calibration (typical): ± 0.5%. Relative power uncertainty C/L-Band: ± 140 mdB (± 120 mdB typ.). Relative power uncertainty O-Band: ± 160 mdB (± 140 mdB typ.). Input power range -38 dBm to +19 dBm. Insertion loss: < 4.0 dB (< 3.5 dB, typ). PDL (typical): < 0.2 dB. Maximum safe input power: 20 dBm.

*This is a Web introductory price for one calibration of the Keysight (Agilent) N7786B. 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
