In modern communications network construction, fiber optic communication has become the preferred choice for backbone and access networks due to its advantages such as high speed, low latency, and interference resistance. In outdoor environments, the performance of fiber optic patch cords (FPCs) is directly related to network stability and service life. In complex outdoor environments, particularly those subject to strong UV radiation, high temperatures, rain, snow, and other natural factors, ordinary FPCs often cannot maintain their excellent performance over time. Therefore, UV-resistant FPCs suitable for outdoor wiring have emerged as a key product for ensuring the stable operation of outdoor fiber optic networks.

UV-resistant FPCs are based on standard FPCs but feature an optimized outer sheath material to achieve long-term resistance to UV radiation. They are typically made of materials such as high-density polyethylene (HDPE), low-smoke zero-halogen (LSZH), or polyvinyl chloride (PVC), and treated with special UV additives to maintain flexibility and abrasion resistance even under prolonged sunlight, preventing cracking, discoloration, or embrittlement. This type of patch cable not only ensures the transmission performance of the optical fiber itself but also significantly extends its lifespan. It is particularly suitable for outdoor applications such as direct burial, duct laying, and overhead cabling.

• Campus fiber optic networks: Fiber optic backbone and access networks within large industrial parks or campuses.
• Urban infrastructure: Smart city projects such as subways, traffic signals, and smart streetlights.
• Telecom operator cabling: Outdoor fiber access, base station-to-base station communications, and metropolitan area network transmission.
• Fiber-to-the-home (FTTH): Overhead wiring or open-air ductwork ensures long-term, stable fiber optic operation in homes.
