Description of aerial fibre installation

Aerial fiber optic cable is typically used when installing outside the pole. It is a fiber optic cable. Because the aerial fiber optic cable is installed externally, it is designed to protect against natural damage or man-made damage and theft. At present, aerial fiber optic cable is mainly used for secondary trunk lines and below. It is typically installed in flat terrain or low-fluctuation areas.

The method of erecting overhead cables is easy to accomplish. It is installed using existing overhead poles. This installation method has its own advantages. It can greatly save construction costs and shorten the construction period. The disadvantage of aerial fiber optic cable is that they are susceptible to natural disasters, external forces and mechanical strength. Aerial fiber optic cables have a higher failure rate than pipes or direct buried cables. In the case of natural disasters such as typhoons, ice, and floods, aerial fiber optic cables are prone to failure.The method of erecting overhead cables is easy to accomplish.

Types of Aerial Fiber Optic Cables

Today, self supporting aerial fiber optic cables are used in large numbers. The installation method of aerial fiber optic cable is generally divided into catenary and self-support. The Catenary Wire Aerial Cable is a conventional outdoor loose tube cable. Catenary Wire Aerial Cables are typically bundled in a spiral form into a messenger or bundled into other cables. This is very common in CATV. In self-supporting overhead cables or all-dielectric self-supporting (ADSS) cables, the principle of operation is to connect the cables to insulated steel or to an all-dielectric signal. The common types of ADSS are shown in the figure. Generally strong metal or aramid strength members can be made into ADSS cables. ADSS cables have a heavier jacket.
