GYTC8S figura 8 red suelta multi del solo modo del tubo G652D de la autoayuda de la base del cable de fibra óptica 2-14
Description
GYTC8S fiber optic cable, the structure of the cable is made of high modulus plastic inpacked waterproof composite loose tube, single mode and multi-mode optical fiber, metal reinforced suspension line, steel-PE cement sheath of self-supporting loose tube twisted outdoor communication cable. There is an FRP in the middle of the cable core. The compact circular cable core is composed of a loose sleeve (packing gasket) and a center reinforced core, and the gap of the cable core is filled with a water-blocking compound. After laying the metal reinforced cable parallel to the cable core, the PE sheath is the cable core, and the cable core is longitudinally covered with a plastic plated plastic steel strip
Main feature
* Precise control of the additional length of the fiber to ensure good tensile resistance and environmental protection characteristics of the cable.
* Double-sided plastic plated steel tape provides an excellent moisture resistance and side compression resistance.
* Galvanized steel strand guarantees the tensile strength required for self-supporting cable installation.
* The cable is suitable for self-supporting overhead wiring with a span of 100m or less. It provides for more efficient construction while saving on suspension lines and cable hangers.
Application field
This product is suitable for long-distance and intra-office communication.
