ADSS Single-mode Optical Fiber Cable

ADSS (All Dielectric Self-Supporting) single-mode optical fiber cable is a fully dielectric self-supporting optical fiber transmission medium specially used for long-distance and high-speed network communication transmission. It adopts all-dielectric structure without any metal conductor inside, which fundamentally avoids the influence of lightning induction and strong current electromagnetic interference, and is very suitable for overhead laying in power line corridors, outdoor overhead lines, cross-road and cross-river long-distance communication scenarios. As a core transmission carrier of modern backbone network, metropolitan area network and remote monitoring network, it has irreplaceable advantages in long-distance and high-stability optical signal transmission.

The single-mode optical fiber core adopted by ADSS cable conforms to international G.652D and G.657A standard specifications, with extremely low optical signal attenuation and dispersion characteristics. It can support long-distance unrelayed transmission, with the effective transmission distance reaching tens of kilometers, far exceeding the transmission limit of ordinary multi-mode optical fibers. This performance makes ADSS single-mode optical fiber cable the preferred choice for long-distance network interconnection between cities, districts and stations, which can effectively reduce the number of relay equipment, save engineering construction costs and simplify the network transmission structure.

The all-dielectric structural design is the core feature of ADSS optical fiber cable. The cable body is composed of optical fiber core, loose tube, filling paste, reinforcing layer and outer sheath, all of which are non-metallic materials. This structure not only eliminates the risk of lightning strike and induced current damage, but also avoids the electric corrosion effect caused by high-voltage electromagnetic field, making it safe to co-lay with high-voltage power lines for a long time. The high-strength aramid fiber reinforcing layer is built in the cable body, which has excellent tensile strength and self-supporting performance, can withstand the tension of long-span overhead laying, and adapt to harsh outdoor environments such as strong wind and low temperature.

In terms of environmental adaptability and service life, ADSS single-mode optical fiber cable adopts high-quality weather-resistant outer sheath materials, which have excellent anti-ultraviolet, anti-aging and low-temperature resistance properties. It can maintain stable physical structure and optical transmission performance in the temperature range of minus 40 degrees Celsius to 70 degrees Celsius, and is not easy to age, crack or deform after long-term outdoor exposure. The loose tube structure and waterproof filling paste inside the cable can effectively prevent moisture intrusion, ensure the dry and stable internal environment of the optical fiber, and avoid signal attenuation and transmission failure caused by moisture.

With the rapid development of 5G communication, smart grid and remote intelligent monitoring systems, ADSS single-mode optical fiber cable has been widely used in power communication networks, municipal backbone networks, traffic monitoring networks and other fields. Its advantages of anti-interference, long transmission distance, high safety and long service life make it a key basic material for building high-stability and long-distance optical fiber communication networks, providing reliable transmission guarantee for modern high-speed information interaction.
