3SAE EndFace Prep Station II

Large diameter optical fibers are increasingly important in the development of new optical technologies. Cleaving these fibers for presents many challenges, more so as the fiber diameter increases. Low angle offsets and smooth, flat endfaces are required. Many fibers are non-round or have internal structures that interfere with conventional cleaving. With some fibers priced in hundreds of dollars per meter, the length of cutoff scrap must be minimized.

The 3SAE EndFace Prep Station meets these challenges with a novel, polishing-based design that now features both flat and angle polishing. The results are consistent, even for shaped fibers. The endfaces are flat and highly polished. The EPS is not an adapted connector polisher – it is a purpose-built LD fiber preparation unit optimized for splicing and other large diameter fiber termination applications.

Choose from a selection of standard programs, or create and store a custom program for a specific fiber. Selectable programs ensure repeatable performance and the bright, clear LCD screen guides the user with the correct action for each step. No special skill or “touch” is required –the EPS’s precision fixturing holds the fibers precisely, and the automated system lowers the fibers smoothly onto the adjustable-speed polishing plate.

A filtered-air final cleaning/drying system is used to dry the fiber after cleaning in the included 3SAE Ultrasonic Cleaner. The 3SAE Ultrasonic Cleaner is a purpose-built ultrasonic fiber cleaner that was designed specifically for fiber applications. Many years of splicing experience went into the functional, ergonomic design that ensures consistent cleaning results. When the preparation process is complete, the fiber endfaces are flat, low-angle, and ready for splicing. Less than 2 mm of scrap length means less wasted expensive fiber and allows more accurate placement of splices and components.
