In addition to the number of fiber cores and fiber type, the structure and sheath of the optical cable should also be selected according to the environment in which the optical cable is used.
1. When outdoor optical fiber cables manufacturer and supplier are directly buried, loose-type armored optical cables should be used. When overhead, black steel bars can be used. The black steel bars have two or more steel PE loose tube optical cable sheaths.
2. When selecting optical fiber cables used in buildings, tight-buffered optical cables should be selected, and attention should be paid to their flame retardancy and toxic smoke characteristics. Generally speaking, the flame-retardant but smoke-free type can be selected for use in pipes or forced ventilation places (Plenum) or the flammable and non-toxic type (LSZH). The flame-retardant environment should be selected for the flame-retardant environment. The non-toxic and smoke-free type (Riser) ).
3. When the fiber cable is laid vertically or horizontally in a building, you can choose tight-buffered optical cables, distribution optical cables or branch optical cables that are common to the building.
4. Single-mode and multi-mode optical cables are selected according to network applications and optical cable application parameters. Multimode fiber optic cables are generally used for indoor and short-distance applications, and single-mode fiber optic cables are used for outdoor and long-distance applications.
