Outdoor cables Briefly cable for outdoor use, are belongs to a fiber optic cable, because suitable for use in outdoor so called outdoor fiber optic cable, it is long-term durability, able to withstand the wind and sun and cold, and packaging thick, having some mechanical properties, environmental properties pressure, corrosion resistance, tensile strength and the like.
Longitudinal seepage water blocking tape longitudinally to prevent the cable
Two parallel steel wires ensure tensile strength
Tensile strength outdoor optical cable is large, the protective layer is relatively thick and heavy, and generally (i.e. metal leather wrapped) is armored. Outdoor fiber optic cable is mainly applied to the interconnection between between buildings, as well as remote network.
In general, the outdoor optical cable is just fillers, reinforcing different member, the jacket and other selected materials. Such as: When outdoor cable buried, should use armored cable. Cable black plastic outer sheath when the aerial, can be selected with two or more stiffeners.
Outdoor cables because it uses the environment is outdoors, it is necessary to have a waterproof function, the outer sheath is generally used is a PE material made, and its internal structure is generally divided into a tubular structure and the layer twisted structure.
From macroscopic point of view, the outer sheath interior is usually yellow or orange PVC material, outdoor black PE material sheath, from the type distinction outdoor generally words GY of.
Outdoor optical cable: packaging thick, having a pressure resistance, some mechanical properties, environmental properties of corrosion, tension and the like.
Indoor cable: mainly used indoors, the main features have flexible features, can be used in the corner and other confined spaces, and secondly there must be fire retardant, tensile, soft extrinsic characteristics.
Outdoor cable is completed optical signal transmission a communication line. By a certain number of optical fibers in accordance with a certain embodiment the composition of the cable core, outer sheath, and some covering outer sheath.
Outdoor cables mainly composed of an optical fiber (as thin as a hair strands of glass) and plastics maintenance sleeve and a plastic sheath configuration, the cable is free of gold, silver, copper and aluminum and other metals.
