Characteristics of outdoor optical cable

Time:2019-03-09 Views:1472
Outdoor optical cable is a kind of outdoor optical cable. It is called outdoor optical cable because it is most suitable for outdoor use. It is durable, can withstand wind and sunshine, freeze in cold weather, and has thick outer packaging. It has some mechanical and environmental characteristics such as pressure resistance, corrosion resistance, tension resistance and so on. Outdoor optical cable is a kind of outdoor optical cable.

Two parallel wires guarantee the tensile strength of optical cable
Outdoor optical cables have higher tensile strength, thicker protective layer and are usually armoured (i.e. metal skin wrapped). Outdoor optical cables are mainly suitable for interconnection between buildings and remote networks.
Generally speaking, outdoor optical cables are just fillers. Different materials are used for strengthening components and sheaths. For example, when buried outdoors, armoured optical cables should be selected. When overhead, two or more black plastic sheaths with reinforcing ribs can be used.
Outdoor optical cable must have waterproof function because its use environment is outdoor. Generally, the outer sheath is made of PE material, and then its internal structure is generally divided into central tubular structure and layered strand structure.
From the naked eye, the indoor jacket is usually yellow or orange PVC material, the outdoor is black PE material jacket, from the model difference between the outdoor is generally GY words.
Outdoor Optical Cable: Thick outer packing, with some mechanical and environmental characteristics such as pressure, corrosion resistance, tension resistance.
Indoor optical cable: mainly used in the interior, the main features should be flexible, can be used in narrow corners and other places, followed by fire retardant, tensile, soft and other external characteristics.
Outdoor optical cable is a communication line to complete optical signal transmission. A certain number of optical fibers form a cable core in a certain way, which is wrapped with sheaths and some with outer sheaths.
Outdoor optical cables are mainly composed of optical fibers (glass filaments as thin as hair) and plastic maintenance sleeves and plastic skin. There are no gold, silver, copper and aluminum metals in the cables.
