⫸ Product Description: [Metal reinforced component, loose sleeve layer fully filled, aluminum flame retardant low smoke and halogen-free bonded inner sheath, steel tape armor, flame retardant low smoke and halogen-free outer sheath communication outdoor optical cable] The structure of the optical cable is to encase single-mode or multi-mode optical fibers in a high modulus plastic filled waterproof compound loose sleeve. The center of the cable core is a metal reinforcement. For some fiber optic cables with a certain number of cores, the non-metallic center reinforcement is wrapped with a polyethylene cushion layer, and the loose sleeve (and filling rope) is twisted around the center reinforcement to form a compact and round cable core. The gaps in the cable core are filled with water-resistant compounds, and the outer extruded aluminum flame retardant low smoke and halogen-free (LSZH) is used. Adhesive inner sheath, steel strip armor is applied to the inner sheath, water blocking compounds are filled in the gaps, and flame-retardant low smoke halogen-free (LSZH) outer sheath is extruded to form a cable.
Laying methods: direct burial, pipeline, etc.
⫸ Scope of application: Suitable for long-distance communication and inter bureau communication, as well as railway, high-speed railway, and subway rail transit places with flame retardant requirements.
⫸ Implementation standard: YD/T 901-2018 layer twisted communication outdoor optical cable.
⫸ Product features: ① Reasonable design and precise control of the remaining length and cabling method of the optical fiber in the loose tube, making the optical cable have excellent mechanical and environmental performance; ② The outer part of the reinforcement and the inner part of the cable core are filled with water-resistant cable paste, ensuring the moisture-proof and water-resistant effect of the optical cable; ③ The double-layer metal strip longitudinal package and double-layer sheath structure ensure strong tensile and lateral pressure resistance, with the ability to prevent rodent damage and good moisture resistance; ④ The sheath is made of flame-retardant LSZH material, which has the advantages of good flame-retardant effect and low smoke concentration during combustion. It can be used in places with flame-retardant requirements, especially in rail transit communication networks.
