Outdoor optical cable, simply put, is an optical cable used outdoors. It is a type of optical cable. It is called outdoor optical cable because it is most suitable for use outdoors. It is durable and can withstand the wind, sun, cold, and freezing. The outer packaging is thick and has some mechanical and environmental properties such as pressure resistance, corrosion resistance, and tensile resistance.
What are the common features of using outdoor optical cables? The water-blocking tape is wrapped longitudinally to prevent longitudinal water seepage of the optical cable. Two parallel steel wires ensure the tensile strength of the 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, and sheaths 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 central tube structure and Layered structure.
From the naked eye, the indoor outer sheath is usually yellow or orange PVC material, and the outdoor sheath is black PE material. The difference from the model is that the outdoor sheath usually has the word GY.
Outdoor optical cable: The outer packaging is thick and has some mechanical and environmental characteristics such as pressure resistance, corrosion resistance, and tensile resistance.
Indoor optical cable: Mainly used indoors. The main features should be easy to bend and can be used in narrow places such as corners. Secondly, it should have external features such as fire resistance, flame retardancy, tensile strength, and softness.
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.
