   Keysight (Agilent) N7784B   Description / Specification:    
Keysight (Agilent) 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
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.

Operating wavelength range: 1260 to 1640 nm.
Wavelength range in stabilizer mode: 1520 to 1580 nm.

Polarization control and stabilization.
SOP switching time (open-loop): < 10 μs.
PER at PMF output (typical): > 23 dB.
Stabilizer response time (typical): 2 ms.

Optical power.
Insertion loss port I to port II: < 3.5 dB (< 3.0 dB, typical).
Insertion loss port III to port IV: < 1.8 dB (< 1.4 dB, typical).
PDL port I to port II (typical): < 0.2 dB (C/L-Band), < 0.5 dB (O-Band).
Maximum safe input power: 20 dBm (Port I), 3 dBm (Port III).
Input power range in stabilizer mode Port III: -30 to 0 dBm.

Multimode Fiber
Multimode Fiber has a large core (almost always 62.5 microns - a micron is one one millionth of a meter - but sometimes 50 microns) and is used with LED sources at wavelengths of 850 and 1300 nm for short distance, lower speed networks like LANs. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Refractive Index
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium. The velocity at which light travels in vacuum is a physical constant, and the fastest speed at which energy or information can be transferred. However, light travels slower through any given material, or medium, that is not vacuum.

Total insertion loss
A measure of the loss of light within an optical component
