Plastic fiber optic cables use one or more optical fibers placed in a protective sleeve as a transmission medium to form individual or group communication cable assemblies. Plastic optical fibers have the advantages of large core diameter, soft texture, easy connection, light weight, low cost, high transmission bandwidth, and therefore occupy an important position in the market of broadband access network systems, home intelligent network systems, data transmission systems, automotive intelligent systems, industrial control systems, as well as textile, lighting and solar energy utilization systems and other applications.
Duplex POF (Polymer Optical Fiber) cable is a type of optical fiber cable that consists of two individual POF strands within a single jacket. POF is a plastic-based optical fiber that uses a transparent core made of polymethyl methacrylate (PMMA) instead of glass. It offers a cost-effective and easy-to-install alternative to traditional glass optical fibers. POF has good resistance to electromagnetic interference (EMI) due to its plastic composition. It is less susceptible to interference from nearby electrical equipment, making it suitable for installations in electrically noisy environments.
The secondary coating refers to the protective layer added to the primary coating or buffer layer of the optical fiber. It can enhance the fiber's ability to withstand longitudinal and radial stress, facilitating further processing of the fiber. Generally, it is divided into two main categories: loose tube coating and tight tube coating.
Halogen-free flame-retardant optical cables use flame-retardant polyethylene sheath material instead of the ordinary polyethylene sheath material of regular optical cables, giving the optical cables flame-retardant properties while maintaining the same structural dimensions, transmission performance, and mechanical and environmental characteristics as regular optical cables.
