The development objective was to produce Polymer Optical Fibers (POFs) with high-temperature stability and a wide spectrum of mechanical properties. Plastic/polymeric optical fibers (POFs) compete with silica fibers for short-distance transmission. POFs are often referred to as consumer optical fibers, because the fiber and its associated optical links, connectors, and installation are all inexpensive. Fibers should have a wide range of glass transition temperature values and utilize a one‑step, environmentally friendly, cost‑effective manufacturing process. Intellisiv has developed a unique method for producing polymer thermoset fibers using an environmentally friendly process at room temperature. The technology is based on fiber spinning and the simultaneous polymerization of monomers using a photopolymerization reaction. Production requires no solvents (not even water) and no post-processing temperature treatment.
