Technologies Polyimide Fiber Preparation Unit II, FPU II,
provides non-contact, chemical free window stripping and end
stripping of polyimide-coated optical fibers in a small, affordable
The FPU II features 3SAE
’s patented Ring of Fire® Technology,
which surrounds the fiber with uniform heat and controlled ionic
conditions. This patented low temperature arc plasma process
window strips or end strips polyimide-coated fibers quickly and
cleanly without mechanical blades, acid or any other chemicals. The
automated process provides consistent stripping results without
requiring special operator skills.
The FPU II is adaptable to your process. Platforms for most fusion
splicer fiber holders are available. Strip lengths are adjustable and
- Polyimide Stripping These tough coatings are difficult to remove without severely degrading the fiber’s mechanical
integrity. Other polyimide stripping technologies use mechanical blades or rapid thermal decomposition, which
produces low tensile strength while leaving the fiber dirty. A more commonly used method, strong acid/alkali
chemistry, is hazardous and produces toxic waste. The FPU II is powered by the 3SAE’s patented Ring of Fire® pulsed
plasma etching technology to remove polyimide coatings safely and cleanly. The standard FPU II accommodates a single
fiber up to 1000um diameter, with appropriate fixtures.
The FPU II’s control interface is accessed via the mounted LCD and Keypad. This interface provides operational status
updates and provides the operator with advanced control of plasma characteristics, temperature and positioning. The
operator can quickly and easily recall and store parameters in any one of up to 8 available recipe locations. This allows
quick translations between fiber stripping programs.
