The 3SAE 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 package.

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 easily programmable.


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 1000 μm diameter, with appropriate fixtures.

User Interface

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 eight available recipe locations. This allows quick translations between fiber stripping programs.
