Large Core Glass Fibers are made from silica glass, which have an extremely large core compared with the optical fiber for tele-communication. They are excellent for transmission of high density optical energy from ultraviolet rays to near infrared rays. Large core glass fibers are mainly used for multimode optical fiber cables, where a pure silica core is surrounded by a region which is doped with some index-lowering agent. Fiberinthebox can provide high quality large core glass fiber cables or custom cables to meet your requirement.
