Because optical fibers are fragile, the optical fibers used in various environments must be processed into optical cables with corresponding mechanical properties to ensure that the optical fibers are not damaged by external forces during the process of laying, installation, use, and maintenance, so as to ensure the smooth flow of the network. . However, the outdoor optical cables and indoor optical cables that are widely used now do not provide fundamental guarantees in terms of these performances in complex environments. Therefore, armored optical cables came into being. Armored fiber optic cable is a kind of fiber optic cable wrapped with a layer of protective “armor”. Its armor is mainly used to protect the fiber optic cable from animal bites, moisture erosion or other damage.
Armored optical cable can be divided into indoor armored optical cable and outdoor armored optical cable according to the application of optical cable. In addition, armored optical cables can also be divided into interlocking armored optical cables and corrugated armored optical cables according to the type of metal armor.
Indoor armored optical cable: Indoor armored optical cable includes single-layer armored and double-layered armored optical cable. Among them, the double-layer armored fiber optic cable is used for offshore shallow seas, and the single-layer armored fiber optic cable is used for other occasions outside these extreme conditions.
Outdoor armored cable: Outdoor armored cable can be divided into light armored cable and heavy armored cable. Usually heavy armored cables are used on the bottom of rivers and submarines, so the price of light armored cables is cheaper than that of heavy armored cables.
Interlocking Armored Optical Cable: The interlocking armor is an aluminum armored cable that is commonly used in indoor and outdoor general environments with high durability and high pressure resistance.
Corrugated Armored Optical Cable: Corrugated armor is formed by wrapping the longitudinal folds of the optical cable with steel tape. It is often used in outdoor environments. It has super mechanical properties and provides protection against rodent bites.
According to different laying environments, armored optical cables can be divided into tight sheathed armored optical cables and loose sheathed armored optical cables. Loose sheathed armored cables are typically used in outdoor applications; tight sheathed armored cables can be used in indoor applications and indoor/outdoor applications.
