Such as ice, snow, water and wind, the purpose is to keep the stress on the fiber optic cable as low as possible, while keeping the sling and fiber optic cable from falling to ensure safety. Generally speaking, aerial fiber optic cable is usually made of heavy-duty sheathing and strong metal or aramid strength Made of components with excellent mechanical and environmental properties, high tensile strength, light weight, easy to install, low cost, type of aerial optical cable. According to the installation method, aerial optical cable can be divided into two types: self-supporting and catenary , Self-supporting aerial fiber optic cable: A self-supporting fiber optic cable has the cables connected to insulated steel or fully insulated messengers to provide support. Examples of self-supporting aerial fiber optic cable types include all-dielectric self-supporting (ADSS) and figure-8 cables.
It provides excellent mechanical and environmental performance, steel wire reinforcement ensures tensile strength, corrugated steel strip, PE outer sheath ensures pressure resistance, water blocking system improves waterproof capability, small diameter of optical cable, low dispersion and attenuation characteristics, GYXTC8Y: GYXTC8Y It is a lightweight self-supporting optical cable with a figure-8 cross-section suitable for installation in overhead environments for long-distance communications, pipelines and buried applications. It provides hydrolysis-resistant high-strength loose tube, excellent mechanical and environmental performance, small Cable diameter, low dispersion and attenuation, medium density polyethylene (PE) jacket and low friction installation characteristics, GYXTC8S: GYXTC8S is also suitable for installation in aerial environments for long-distance communications. Corrugated steel strip and PE outer sheath ensure pressure resistance, water blocking system improves waterproofing capability, small diameter of optical cable, and low dispersion and attenuation characteristics. Application scenarios, overhead optical cables are used to transmit electronic signals, such as telephone communications, optical cable services, and even As part of the local community power distribution system, In addition, aerial fiber optic cables are used in outdoor overhead applications, long-distance and local area networks (LAN), metropolitan area networks (MAN), user network systems, connected communication systems, CATV and computer network systems, Summary, overhead Optical cables can be laid using the original overhead open wire poles, which saves construction costs and shortens the construction period. It is suitable for areas with flat terrain and small fluctuations.
It is often used with power lines or in areas where lighting often occurs, whereas a figure 8 self-supporting sling is a steel strand, which is metal, in the structure of a figure 8 fiber optic cable the central strength member can be steel wire or FRP , non-self-supporting overhead fiber optic cables need to be suspended below a sling, Catenary overhead fiber optic cable: Catenary overhead fiber optic cable is a common outdoor loose tube cable that can be tied to a sling or another fiber optic cable (common in CATV), According to the structure and materials of aerial optical cables, optical cable manufacturers can be divided into three main types: GYTC8S, GYXTC8S and GYXTC8Y. GYTC8S: GYTC8S is a typical self-supporting outdoor optical cable.
Aerial optical cables are very common in optical communications nowadays. We can see aerial optical cables hanging on power poles around you. Since aerial optical cables are exposed to harsh outdoor environments, the materials used to make aerial optical cables must be strong and durable. Fiber optic cables are available in a variety of designs to suit different types of overhead applications. This article can help you learn more about aerial fiber optic cables. What is aerial fiber optic cables? , an aerial fiber optic cable is an insulated fiber optic cable that usually contains all the optical fibers required for telecommunications lines. It is suspended between utility poles or power towers, as it can even be made with small gauge wires tied to wire rope slings, and the stranded wires are tensioned To satisfactorily bear the weight of the fiber optic cable across the span length.
