Description
Technical field
This utility model relates to optical cable field, specifically a kind of central tubular ligth armoring optical cable.
Background technology
Armored fiber optic has important application in telecommunication optical fiber intercity line, one or two grades of primary transmission. But the armored fiber optic that general webmaster generally touches, is mostly used for inside machine room building and connects two optical network units all. Such armored fiber optic length is relatively short. It is commonly referred to armored jumper. Advantage: high tensile, high resistance to compression, mouse bite preventing; Possess and can resist the damage of torsional bending improperly; Easy construction, saves maintenance cost; Adapt to various adverse circumstances and artificial damage. Generally in screw bolt-type, protect fibre core with layer of metal armour, it is possible to natural torsion, have high pressure resistant, the advantage of anti drawing strongly, it is possible to provide excellent optical ca ble protection and safety.
Existing central tubular ligth armoring optical cable integral waterproofing poor-performing, it is impossible to realize longitudinal waterproof so that the overall situation easily occurring making moist so that overall operation is unstable.
Utility model content
The purpose of this utility model is in that to provide a kind of central tubular ligth armoring optical cable, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of central tubular ligth armoring optical cable, including oversheath, the inwall of described oversheath is laid with plastic-coated steel band, utilizes plastic-coated steel band can increase the intensity of entirety, can realize the effect of protection against the tide simultaneously; The inner side of described plastic-coated steel band is provided with Loose tube, and is provided with water blocking layer between Loose tube and plastic-coated steel band, utilizes water blocking layer to realize stronger water resistance, makes entirety compacter simultaneously, it is achieved longitudinal waterproof; The inner side of described Loose tube is provided with multifiber, the outside of optical fiber and the boundary area filling inside Loose tube has sleeve pipe implant, the diameter proportion of described Loose tube diameter and oversheath is 1:8, and sleeve pipe implant adopts waterproofing compound to make, thus realizing inner side waterproof.
As further program of the utility model: described oversheath inner clip is equipped with two symmetrically arranged steel wires, and steel wire improves overall anti-pull property so that bulk strength is higher.
As this utility model further scheme: described oversheath adopts polyethylene material to make.
Compared with prior art, the beneficial effects of the utility model are: this utility model is simple and reasonable, arrange water blocking layer between Loose tube and plastic-coated steel band, utilize water blocking layer to realize stronger water resistance, make entirety compacter simultaneously, it is achieved longitudinal waterproof; The inwall of oversheath is laid with plastic-coated steel band, utilizes plastic-coated steel band can increase the intensity of entirety, the effect of protection against the tide can be realized simultaneously, thus entirety not only has higher intensity, there is good water resistance simultaneously.
