The center of the fiber optic cable is usually a core made of glass. The core is surrounded by a layer of glass envelope with lower refractive index than the core, so that the optical signal into the fiber core is reflected by the cladding interface, so that the optical signal travels forward in the fiber core. Because the fiber itself is very fragile, can not be directly applied to the wiring system, so usually tied into a bundle, outside the protective shell, the middle of the anti-tension cable, this is the so-called fiber optic cable, usually contains one or more fibers.
Indoor optical fiber cable
According to the different use environment, fiber optic cable can be divided into indoor fiber optic cable and outdoor fiber optic cable.
Indoor fiber optic cables are classified according to the use environment of the cable, as opposed to outdoor fiber optic cables.
Indoor optical cable is a cable formed by optical fiber (optical transmission carrier) through a certain process. It is mainly composed of optical fiber (glass wire as thin as hair) and plastic protective sleeve and plastic skin. There is no metal such as gold, silver, copper and aluminum in the optical cable, and it generally has no recycling value.
Indoor fiber optic cable is a certain number of optical fibers in accordance with a certain way to form the core of the cable, outsource a sheath, some also coated with an outer sheath, to achieve optical signal transmission of a communication line.
Indoor fiber optic cables have low tensile strength and poor protective layer, but they are also more lightweight and economical. Indoor fiber optic cables are mainly suitable for wiring in buildings, as well as connections between network devices.
Indoor cable features:
Indoor fiber optic cable has less tensile strength and poor protection layer, but it is relatively lighter and more economical. Indoor fiber optic cable is mainly suitable for horizontal wiring subsystem and vertical backbone subsystem. Outdoor fiber optic cables have high tensile strength, thick protective layer, and are usually armored (that is, wrapped in metal leather). Outdoor fiber optic cable is mostly used in building subsystems, and can be used in outdoor direct buried, pipeline, overhead and underwater laying occasions.
Outdoor optical fiber cable
Outdoor fiber optic cable, used for outdoor fiber optic cable. At the other end of the spectrum are indoor fiber optic cables.
Outdoor optical cable is a kind of communication line to realize optical signal transmission. The core of the cable is composed of a certain number of optical fibers in a certain way, with an outer sheath and some coated with an outer sheath.
Outdoor cable features:
It is mainly composed of optical fiber (glass wire as thin as hair) and plastic protective sleeve and plastic skin. There is no metal such as gold, silver, copper and aluminum in the optical cable, and it generally has no recycling value.
Outdoor fiber optic cables have high tensile strength, thick protective layers, and are usually armored (that is, wrapped in metal leather). Outdoor fiber optic cable is mainly suitable for the interconnection between buildings and remote networks.
