Abstract
The present case is an optical cable of high strength, includes: the oversheath, it is outermost inoxidizing coating, first two -sided plastic -coated steel band, it is located the oversheath inner circle, the inner sheath, it is located the inlayer of first two -sided plastic -coated steel band, the two -sided plastic -coated steel band of second, it is located the inlayer of inner sheath, the optical fiber ribbon, it comprises the multifiber, PBT loose tube will the mode of optical fiber ribbon parcel is located its skin, and it is located the intermediate position of optical cable, the fine cream that blocks water, it is filled and is in in the PBT loose tube, hinder water -blocked cable cream, it is in with the spraying mode on the two -sided plastic -coated steel band of second fill in the two -sided plastic -coated steel band of second with between the PBT pine sleeve pipe, metal reinforcement, its metal reinforcement who is two symmetries is located respectively the both sides of optical fiber ribbon. The present case can guarantee that the optical cable has outdoor optical cable advantage and is suitable for in the outdoor cloth characteristics such as put of laying.
Description
Technical field
The utility model relates to optical cable, particularly relates to a kind of optical cable of high strength.
Background technology
The technology that usual outdoor filled type communications optical cable is identical, only in the difference of filling cable cream part, ointment pump or other factice for filling parts can not be used, spraying cable cream device is installed, be sprayed on steel, aluminium strip by special for spraying cable cream before steel, aluminium strip enter preforming tool, each rice sprays half meter of cable cream; If alone spraying can not play block-water effect, can use before spraying and fill cable cream, and use vulcanite scraper cream mould all to be struck off by cable cream all around cable core, only stay the cable cream at the stranded place of cable core, re-use spraying afterwards.Purposes due to inside cable determine the resistance to tension of optical cable poor, there is no stop water yet, be not suitable for laying use in pipeline, sewage and mouse etc. may be there is in pipeline simultaneously, simultaneously, existing optical cable can produce deformation or damage under bang, and cable lifetime is in the presence of a harsh environment seriously affected by environment.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is the optical cable providing a kind of high strength, is intended to realize one not easily deformation, the optical cable that the life-span is longer.
For achieving the above object, the utility model is achieved through the following technical solutions:
An optical cable for high strength, comprising:
Oversheath 1, it is outermost protective layer;
First double plastic-coated steel band 2, it is positioned at described oversheath inner ring;
Inner sheath 3, it is positioned at the internal layer of described first double plastic-coated steel band;
Second double plastic-coated steel band 4, it is positioned at the internal layer of described inner sheath;
Fibre ribbon 8, it is made up of multifiber;
PBT pine pipe box 9, the mode that described fibre ribbon wraps up is positioned at its skin, it is positioned at the centre position of described optical cable;
Block water fine cream 7, and it is filled in described PBT pine pipe box;
Block water cable cream 5, and it is filled between described second double plastic-coated steel band and described PBT Loose tube in the mode be sprayed on described second double plastic-coated steel band;
Metal reinforcement 6, it is two symmetrical metal reinforcements, lays respectively at the both sides of described fibre ribbon.
Preferably, the optical cable of described high strength, wherein, described oversheath is medium density polyethylene, i.e. MDPE protective layer.
Preferably, the optical cable of described high strength, wherein, described inner sheath is medium density polyethylene, i.e. MDPE protective layer.
Preferably, the optical cable of described high strength, wherein, described fiber cores is made up of 12 to 144 optical fiber.
Preferably, the optical cable of described high strength, wherein, described PBT pine pipe box material is polybutylene terephthalate.
Preferably, the optical cable of described high strength, wherein, described metal reinforcement material is stainless steel.
The beneficial effects of the utility model: the utility model structure is simple, under the prerequisite using jet printing type optical cable not affect at optical cable permeability performance, effectively can save great amount of cost, do not use and fill cable cream or use a small amount of filling cable cream, directly on steel band, spray one deck sprays special cable cream, can save a large amount of starting material every year, and the block-water effect spraying cable cream is better than the block-water effect of filled type cable cream; Adopt and the first double plastic-coated steel band and the second double plastic-coated steel band are set respectively at oversheath and inner sheath inner ring, two symmetrical metal reinforcements are also set in the both sides of fibre ribbon, spraying waterproof cable cream between some sub-optical cable units in the second plastic-coated steel band, effectively prevent the infringement that the various factors such as sewage and mouse causes optical cable, ensure that the serviceable life of optical cable, be highly suitable for construction usage in pipeline; Simultaneously because optical fiber is belt like combination, substantially increase optical fiber dense degree, adapt to the requirement that fiber cable network expansion optical distribution cable branch increases; Less optical cable external dimensions and square-section make it easy between building, building and internal channel Jian He building, building internal channel lay fixing and should not slide, and so just can ensure that optical cable has outdoor optical cable advantage and is suitable in features such as outdoor laid lay again.
