According to the use of fiber optic cable environment should be how to choose fiber optic cable?

In addition to the number of fiber cores and fiber type, the structure and sheath of the optical cable should be selected according to the environment in which the cable is used.1. When the outdoor optical cable is buried directly, it is preferable to choose loose-sleeved armored optical cable. When overhead, black steel can be selected, black steel has two or more steel PE loose sheath fiber optic cable sheath.2. When selecting fiber optic cables to be used in construction, tightly sheathed fiber optic cables should be selected and attention should be paid to their flame retardant . Characteristics of toxic smoke. In general, flame retardant but smoky types can be selected in ducts or forced ventilation (Plenum) or combustible non-toxic types (LSZH). flame retardant environments should be selected for flame retardant environments . Non-toxic and smoke-free type (Riser).3. When the cable is laid vertically or horizontally in the building, the tightly jacketed fiber optic cable common to the building can be selected . Wiring fiber optic cables or branching fiber optic cables.4. Single-mode and multimode fiber optic cables are selected according to network applications and fiber optic cable application parameters. Indoor and short distance applications generally use multimode fiber optic cable, outdoor and long distance applications use single-mode fiber optic cable. In fiber optic connection, how to choose between fixed connection and movable connection for different applications? Fiber optic connectors enable movable connections of optical fibers through fiber optic connectors. The movable connection point in the optical chain is a clear split interface. When choosing between moveable and fixed connections, the low cost reflects the advantages of fixed connections . Light loss is minimal but less flexible, while the opposite is true for movable connections.
