This specification covers the construction all dialectic self-supporting Optical Fiber Cable (ADSS) properties for outdoor application. The optical fiber cable contains 24 cores (6cores/tube) single mode ITU-T G. Then, two layers of aramid fibers are twisted bidirectionally for reinforcement, and finally a polyethylene outer sheath or an electric tracking. Its all-dielectric self-supporting (ADSS) design allows it to be installed directly on utility poles or between towers, making it ideal for challenging environments where traditional cabling methods fall short.
