LFS-4100 Large Diameter Fiber Splicer

The LFS-4100 is a dedicated process tool for splicing standard, large diameter and specialty fibers. Designed for volume production of fiber assemblies, it is intended for manufacturers that want the splicing performance of Vytran’s proven filament fusion, multi-function splicing and glass processing products, but from a stand-alone, easy-to-use tool.
The LFS-4100 uses our patented filament fusion technology to produce low-loss splices on fibers ranging from 125 µm to 1.25 mm in diameter. It can be used for standard and specialty fibers such as doped fibers, polarization maintaining (PM) fibers, large mode area (LMA) fiber, photonic crystal fiber (PCF), highly stressed fibers and D shapes. It features PC-based software with two screens – one tailored for product development that allows all of the unit’s functionalities, and another simplified screen that allows basic operator interface for easy, consistent, volume manufacturing.

The LFS-4100, the GPX-3400 glass processing system, the LDC-400 fiber cleaver, and the PTR-200 series of fiber recoaters and proof testers make up a suite of complementary products. The LFS-4100, GPX-3400 and LDC-400 share a fiber holding block to ensure accurate fiber positioning. LFS and GPX systems also feature application libraries to help streamline processes from development to manufacturing.
