What are the general characteristics of Outdoor Optical Cable？

Outdoor optical cables have greater tensile strength, thicker protective layers, and are usually armored (that is, wrapped in metal skin). Outdoor optical cables are mainly suitable for interconnection between buildings and remote networks.
Generally speaking, outdoor optical cables are just fillers, reinforcing members, sheaths, etc. made of different materials. For example: when outdoor optical cables are directly buried, armored optical cables should be used. When used overhead, an optical cable with a black plastic outer sheath with two or more reinforcing ribs can be used.
Because the outdoor optical cable is used outdoors, it must be waterproof. The outer sheath used is generally made of PE material, and its internal structure is generally divided into a central tube structure and a layered structure.
Outdoor optical cable: The outer packaging is thick and has some mechanical and environmental characteristics such as pressure resistance, corrosion resistance, and tensile resistance.
Outdoor optical cable is a communication line that completes optical signal transmission. A cable core is composed of a certain number of optical fibers in a certain way, and is covered with a sheath, and some are also covered with an outer sheath.
Outdoor optical cables are mainly composed of optical fibers (glass filaments as thin as hair), plastic protective sleeves and plastic outer sheaths. There are no gold, silver, copper, aluminum and other metals in the optical cables.
