   KEYSIGHT N7784B   Description / Specification:    
KEYSIGHT N7784B 1260 to 1640 nm High Speed Polarization Controller

The Keysight N7784B polarization controller contains a high-speed polarization controller plus microcontroller-based driving circuitry. It can operate in various modes.
As a polarization stabilizer, it provides a stable output state of polarization (SOP) even with fluctuations
and drifts of the input SOP as occurring for example through temperature drift and mechanical settling
processes.
As a synchronous scrambler, the device switches the SOP of the output signal in a random (pseudo) way.
As an SOP switch, the N7784B allows switching the internal waveplates to user definable angles with
very high speed and repeatability.
As traditional scrambler the N7784B varies the output SOP smoothly in a random/pseudo random way.

Standard Calibration $875.00 *
*This is a Web introductory price for one calibration of the KEYSIGHT N7784B. 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.

Absolute Wavelength Accuracy
Absolute Wavelength Accuracy is the maximum difference between the actual wavelength and the displayed wavelength of the Optical Source. Wavelength is defined as wavelength in vacuum.

Decibel (dB)
A unit of measurement of optical power which indicates relative power. A -10 dB means a reduction in power by 10 times, -20 dB means another 10 times or 100 times overall, -30 means another 10 times or 1000 times overall and so on.

Nanometer (nm)
A unit of measure used to measure wavelength of light, meaning one one-billionth of a meter

Relative Intensity Noise (RIN)
Relative intensity noise (RIN), describes the instability in the power level of a laser. The noise term is important to describe lasers used in fiber-optic communication and LIDAR remote sensing. It is the square of the (spectrally resolved) RMS optical power amplitude divided by the measurement bandwidth and the square of the average optical power, expressed in dB/Hz.

Total Return loss
In an optical fiber, the loss that takes place at any discontinuity of refractive index, especially at an air-glass interface such as a fiber endface, at which a fraction of the optical signal is reflected back toward the source. RL = - 10log10 (Preflected/Preference)
