Introduction
The Agilent N7784B polarization controller contains a
high-speed polarization controller plus microcontroller-
based driving circuitry. This unit 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. The
stabilized output signal is guided in a polarization main-
taining fiber (PMF). Alternatively, an external electrical
feedback signal can be provided for stabilizing the SOP.
As a synchronous scrambler, the device switches the
www.DatSaSOhPeeotf4tUh.ecoomutput signal in a random (pseudo) way.
Switching of the SOP occurs within a few microseconds.
The SOP is stable for a predefined time until it again
switches to a new SOP. An electrical trigger input can be
used to synchronize the scrambler with external events.
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.
The unit does not contain any moving parts and there-
fore is robust and withstands even rough environmental
conditions. All above-mentioned applications of the
N7784B are supported by a PC software package.
● PC-based application software comes with
this instrument.
● Other instrument drivers for various software
interfaces are available.
