Optical fiber manufacturing processes include the addition of a polymer layer to the glass fiber to provide protection, flexibility and strength. Also used for wire and cable marking. Increased profitability through significant reduction of electrical consumption, increased. Phoseon Technology's Fiber Curing System consists of a high intensity UV LED light source, which cures the coatings protecting the glass fibers, along with a patented Fiber Reflector Unit (FRU) to direct the UV energy uniformly around the circumference of the fiber. The UV LED light source and FRU. Traditional mechanical fasteners and slow-curing thermal epoxies are increasingly being replaced by these light-curable systems, which offer on-demand curing and exceptional optical clarity.
