What is a self-supporting aerial optical cable? Self-supporting aerial optical cable (self-supporting cable), also known as "self-supporting optical cable", refers to a cable that integrates a weight-bearing object and a cable or optical cable as a whole.
For example, in optical fiber communications, it is used for optical cables on high-voltage transmission line towers.
The full name of self-supporting aerial optical cable is full-media self-supporting optical cable, which means that the reinforced components of the optical cable can withstand its own weight and external loads.
This name points out the usage environment of this optical cable and its key technologies: because it is self-supporting, its mechanical strength is very important; the use of all-dielectric materials is because the optical cable is in a high-voltage and strong electric environment. It must be able to withstand the influence of strong electricity; since it is used overhead on a power tower, there must be matching pendants to fix the optical cable on the tower.
Also called ADSS optical cable, All-dielectric Self-supporting Optical Cable (all-media self-supporting optical cable), suitable for long-distance communication and inter-office communication.
There are three key technologies for self-supporting aerial optical cables: mechanical design of optical cables, determination of suspension points, and selection and installation of supporting hardware.
It has the following characteristics: 1. The optical fiber has small transmission loss and low dispersion; 2. The optical cable has excellent mechanical properties and environmental performance; 3. The structure is compact and adopts SZ layer stranding structure to ensure that the optical fiber does not Stress; 4. The optical cables are all non-metallic structures, light weight, easy to lay, and strong against electromagnetic interference; 5. The optical cables are self-riding, with high tensile strength, strong resistance to external environments, flexibility and bending resistance of the optical cables powerful.
