The plastic clad silica fiber core is made of high-purity quartz glass, and its hard plastic coating can provide higher tensile strength, which can better block the influence of moisture than conventional quartz coating. The plastic coating is made of fluorinated acrylic resin material, which serves as a coating layer and a cladding layer for optical fibers. This type of optical fiber can be widely used in fields of communication, industry, and near-infrared spectroscopy.

It can be used in fields such as laser transmission, near-infrared spectroscopy detection, fiber optic lighting, medium to short distance communication, power signal transmission, locomotive traction control, medical sensing, laser medical and surgical care, optical temperature measurement, nuclear radiation monitoring, etc.
