Abstract

The present case is an optical cable of two sheaths in area, includes: the oversheath, it is outermost inoxidizing coating, two -sided plastic -coated steel band, it is located the oversheath inner circle, the inner sheath, it is located the inlayer of two -sided plastic -coated steel band, the optical fiber ribbon, it comprises the multifiber, PBT loose tube will the mode of optical fiber ribbon parcel is located its skin, the fine cream that blocks water, it is filled and is in in the PBT loose tube, metal reinforcement, it is located the center of optical cable, it is individual that little gasket for packing, its quantity are the even number, fills to be in in the middle of the PBT loose tube, hinder water -blocked cable cream, it is in with the spraying mode on the two -sided plastic -coated steel band fill in in the two -sided plastic -coated steel band. 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, little gasket for packing, its toughness and intensity of having strengthened the optical cable have still been filled in the vacancy.

Description

A kind of optical cable with two sheath

Technical field

The utility model relates to, and particularly relates to a kind of optical cable with two sheath.

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; cable lifetime is in the presence of a harsh environment seriously affected by environment; optical cable of the prior art generally only has one deck sheath, and the dynamics of protection is large not enough.

Utility model content

For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of optical cable with two sheath, is intended to realize the duplicate protection to optical cable, avoids the damage that it is subject under rugged surroundings again.

For achieving the above object, the utility model is achieved through the following technical solutions:

With an optical cable for two sheath, comprising:

Oversheath 1, it is outermost protective layer;

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 double plastic-coated steel band;

Fibre ribbon 5, it is made up of multifiber;

PBT pine pipe box 4, is positioned at by the mode that described fibre ribbon wraps up in its skin;

Block water fine cream 6, and it is filled in described PBT pine pipe box;

Metal reinforcement 7, it is positioned at the center of described optical cable;

Little gasket for packing 8, its quantity is even number, is filled in the middle of described PBT pine pipe box;

Block water cable cream 9, and it is filled in described double plastic-coated steel band in the mode be sprayed on described double plastic-coated steel band.

Preferably, the optical cable of the two sheath of described band, wherein, described oversheath is medium density polyethylene, i.e. MDPE protective layer.

Preferably, the optical cable of the two sheath of described band, wherein, described inner sheath is medium density polyethylene, i.e. MDPE protective layer.

Preferably, the optical cable of the two sheath of described band, wherein, described fibre ribbon is made up of 12 to 144 optical fiber arrangement rectangular in form.

Preferably, the optical cable of the two sheath of described band, wherein, described PBT pine pipe box material is polybutylene terephthalate.

Preferably, the optical cable of the two sheath of described band, wherein, described metal reinforcement material is stainless steel.

Preferably, the optical cable of the two sheath of described band, wherein, described little gasket for packing is that solid PE restricts.

The beneficial effects of the utility model: the utility model structure is simple, effectively great amount of cost can be saved under the prerequisite using jet printing type optical cable not affect at optical cable permeability performance, directly on steel band, spray one deck sprays special cable cream, and every 1 meter of length can fill about half meter, save most ointment, and play good block-water effect; Adopt the double protection at oversheath and inner sheath, spraying waterproof cable cream between some sub-optical cable units in 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; Also be filled with little gasket for packing in vacancy, it reinforces toughness and the intensity of optical cable.

Accompanying drawing explanation

Fig. 1 is the structural representation of the optical cable of the two sheath of the band described in the utility model one embodiment.

Wherein, 1-oversheath, 2-double plastic-coated steel band, 3-inner sheath, 4-PBT pine pipe box, 5-fibre ribbon, 6-blocks water fine cream, 7-metal reinforcement, the little gasket for packing of 8-, and 9-blocks water cable cream.
