KEYSIGHT N7786B Polarization Synthesizer

The Keysight 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.

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 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.

Chromatic Dispersion
Chromatic Dispersion is a broadening of the input signal as it travels down the length of the fiber. Chromatic Dispersion results from a variation in propagation delay with wavelength, and is affected by fiber materials and dimensions.

A Detector is a signal conversion device that converts power from one form to another, such as from optical power to electrical power

Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Polarization Mode Dispersion (PMD)
Polarization mode dispersion (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical pulses. It is he difference between the maximum and minimum values of loss typically measured in ps/km^1/2.
