Abstract
The utility model relates to a self-bearing optical cable laid on the top layer of an environment-protection mouse-proof light drainage pipeline. The inner part of a cable core is provided with a central reinforcing element, an optical fiber and a sleeve pipe of the optical fiber; a metal armouring layer, an inner sheath, an aramid fibre reinforcement layer, an outer sheath and a mouse-proof protective layer are coated at the outside of the cable core orderly, wherein the inner part of the aramid fibre reinforcement layer is provided with a water-blocking yarn. The optical cable has the advantages of good waterproof property, high tensile strength and little possibility of being damaged, can be prevented from being damaged by mice, and can be normally used when laid in severe environment, such as in the drainage pipelines. The utility model can accommodate the development requirement of communication network at city areas.
Description
Technical field
The utility model relates to a kind of communications optical cable, especially is applicable to the self-support cable in the drainage pipeline that can be laid in the city field network system.
Background technology
Along with developing rapidly of metropolitan area communication network, adopt general pipeline laying optical cable can not satisfy the needs of network layout, utilize ready-made drainage pipeline laying optical cable to become to satisfy a kind of effective way of MAN wiring demand.Because moist in the drainage pipeline, foreign material are many and often have mouse to haunt, the existing communication optical cable uses in this environment and easily causes damage.
Summary of the invention
In order to overcome the deficiency that the existing communication optical cable is not suitable for laying in drainage pipeline, the utility model provides that a kind of water resistance is good, tensile strength is high and can prevent the new optical cable that mouse damages.
Self-support cable is laid on the environmental protection protection against rodents lightweight drainage pipeline upper strata that the utility model provides, comprise cable core (7) and oversheath (11), be provided with central reinforce member (5), optical fiber (1) and sleeve pipe (3) thereof in the cable core (7), between cable core (7) and oversheath (11), set gradually metal armouring layer (8), sheath (9), aramid fiber enhancement Layer (10), outside oversheath (11), coat protective layer (12).
In order further to strengthen water resistance of the present utility model, in aramid fiber enhancement Layer (10), be provided with water blocking yarn (4).
Be filled with in the ferrule of the present utility model (3) in fine cream (2), the cable core (7) and be filled with cable cream (6), gasket for packing (13) also can be set in cable core (7) as required.
The beneficial effects of the utility model are to have better waterproof energy and bigger tensile strength, be coated on the outer protective layer (12) of oversheath (11) and can prevent that mouse from damaging optical cable, the utility model be installed in when in drainage pipeline, laying pipeline above, when flowing through pipeline, can not washed out in big flood yet, even having foreign material to be suspended on the optical cable behind the big flood also can bear, can not make optical cable impaired, guarantee proper communication.
Description of drawings
Fig. 1 is the novel cross sectional representation of this reality.
In Fig. 1,1. optical fiber, 2. fine cream, 3. ferrule, 4. water blocking yarn, 5. central reinforce member, 6. cable cream, 7. cable core, 8. metal armouring layer, 9. sheath, 10. aramid fiber enhancement Layer, 11. oversheaths, 12. protective layers, 13. gasket for packings.
Embodiment
Central reinforce member of the present utility model and the outer binder layer in the stranded back of loose tube fiber, gasket for packing that is arranged on around it are made cable core (7), outside cable core, coat armor (8), polythene inner (9), the aramid fiber enhancement Layer (10) made by aluminium strip or steel band more successively, when coating the aramid fiber enhancement Layer, water blocking yarn (4) is wrapped into wherein the protective layer (12) that outside aramid fiber enhancement Layer (10), coats tygon oversheath (11) again and make with nylon or other rodent-proof material (as: the extraordinary polyolefin copolymer material of high rigidity).
Claims (2)
1, self-support cable is laid on a kind of environmental protection protection against rodents lightweight drainage pipeline upper strata, comprise cable core and oversheath, be provided with central reinforce member, optical fiber and sleeve pipe thereof in the cable core, it is characterized in that between cable core and oversheath, setting gradually metal armouring layer, sheath, aramid fiber enhancement Layer, cover protective layer in the oversheath outsourcing.
