FTTH Outdoor Fiber Optic Cable

FTTH outdoor fiber optic cable is a robust and versatile optical transmission medium engineered to withstand the rigors of outdoor environments while delivering high-speed, stable data transmission for FTTH networks. Unlike indoor fiber cables, it is designed to resist a wide range of environmental challenges, including extreme temperatures, moisture, ultraviolet radiation, rodent damage, and mechanical stress, ensuring uninterrupted connectivity between central offices, optical distribution points, and end-user premises. This cable plays a pivotal role in the FTTH infrastructure, serving as the backbone of the outdoor optical network that bridges the gap between the core network and the final connection to homes and businesses.

Constructed with durability and performance in mind, FTTH outdoor fiber optic cable typically features a multi-layer protective structure. The core consists of single-mode fibers (often G.657A2/B2 standard) with excellent bending resistance, allowing for minimum bending radii as small as 5mm, which simplifies installation in tight spaces. Surrounding the fiber core are two parallel galvanized steel strands or FRP strength members, providing strong tensile and compressive strength to withstand the forces of wind, ice, and installation stress. The outer sheath is made of high-quality LSZH or polyethylene material, which is not only waterproof and moisture-proof (with a water blocking rate of less than 0.01dB/km) but also resistant to UV radiation and rodent bites—some models even feature glass fiber-reinforced sheaths for enhanced rodent protection. The cable’s operating temperature range of -40℃ to +70℃ ensures it can perform reliably in both frigid and hot climates, with a service life of up to 25 years in high-UV areas.

FTTH outdoor fiber optic cable supports various installation methods, including aerial, duct, and direct burial, making it adaptable to different outdoor scenarios such as rural "village-to-village" broadband projects, industrial parks, and smart city monitoring systems. It is available in different fiber counts to accommodate varying network scales, from small residential communities to large commercial areas. The cable also supports cold splicing technology, which allows for quick and easy termination without the need for expensive fusion splicing equipment, reducing installation time and labor costs. With its excellent environmental adaptability, mechanical strength, and optical performance, FTTH outdoor fiber optic cable is the cornerstone of reliable, high-speed FTTH networks, enabling the delivery of broadband, IPTV, and other high-bandwidth services to end users.
