The OFR Polarization
Controller replaces conventional looped fiber types,
yet performs the same functions. It consists of the
Fiber-to-Fiber Coupling System with appropriate Retarder
Component Modules.
Control of polarization is achieved
through the use of 1/4-Wave and 1/2-Wave Retarders whose
parameters are not affected by environmental changes
on the fiber. This accounts for the stability of the
OFR Polarization Controller.
A Linear Polarizer is
the third Module in the PC-FFB. It precedes or follows
the 1/4-Wave and 1/2-Wave Retarders (in that order)
according to the application. See www.ofr.com/fiberbenches/
polarizationcontroller.
In
contrast, looped fiber controllers are sensitive to
environmental changes, and therefore must be frequently
adjusted.
In all FiberBench Coupling Systems using
OFR PM Fiber-Cables, both the fast axis and the FC receptacle
key-way are vertical. Both the plane of polarization
and the fiber stress rods are horizontal.
A major
feature of OFR FiberBench Coupling Systems is stability.
Transmittance remains constant after temperature change,
shock and vibration far greater than experienced in
typical laboratory use.
