Features
The longitudinal zone of the water blocking zone prevents longitudinal seepage of the optical cable.
Two parallel steel wires ensure the tensile strength of the optical cable.
The tensile strength of outdoor optical cables is relatively high, the protective layer is thicker and heavier, and it is usually armoured (i.e. covered with metal skin). Outdoor optical cables are mainly used for interconnection between buildings and remote networks.
Generally speaking, outdoor optical cable is only a filler, and different materials are used to strengthen components and sheath. For example, when the outdoor optical cable is buried directly, the armoured optical cable should be selected. In case of overhead, a black plastic sheath with two or more stiffeners can be selected.
Outdoor fiber optic cable must have waterproof function because its use environment is outdoor. The outer sheath is usually made of PE material. Then its internal structure is generally divided into central tubular structure and layer stranded structure.
Outdoor optical cable: thick outer package, with pressure, corrosion, tensile and other mechanical characteristics, environmental characteristics.
Outdoor optical cable is a communication line for optical signal transmission. The cable core is composed of a certain number of optical fibers in a certain way. Some of them are covered with sheaths or outer sheaths.
Outdoor fiber optic cables are mainly composed of optical fibers (such as hair glass) and plastic maintenance sleeves and plastic coats. There are no gold, silver, copper and aluminum in the cables.
