Abstract
The invention relates to a full-dry high count armour indoor and outdoor optical cable comprising a reinforcement, a plurality of unit cables, an inner sheath, a metal armour cover and an outer sheath, wherein the reinforcement is arranged in the center, a plurality of unit cables are arranged on the periphery of the central reinforcement in a twisting mode, the inner sheath is covered on the periphery of unit cables, the metal armour cover is sheathed on the periphery of the inner sheath, the outer sheath is covered on the periphery of the metal armour cover, and each unit cable comprises a loose tube and a plurality of tight-coated fibers arranged in the loose tube. Because the optical cable of the invention is provided with the metal armour cover, the steel cable has certain side pressure proof performance, moist resistance performance and rat damage resistance and can be applied indoors and outdoors. The optical cable of the invention has small weight, does not contain liquid such as ointment and the like and is the full-dry optical cable, so that the optical cable is convenient to lay and continue.
Description
Technical field
The present invention relates to a kind of communications optical cable.
Background technology
Insert (the FTTH of family at optical fiber, Fiber To The Home) in the application, optical cable laying mainly adopts optical cable as depicted in figs. 1 and 2 to be used between building, wherein, optical cable shown in Figure 1, its center is a reinforcement 10, at the stranded a plurality of unit cable 20 that is provided with of reinforcement 10 peripheries, periphery at unit cable 20 coats sheath 30, is provided with multifiber 201 in each unit cable 20, and this kind optical cable is mainly as the light line between building, after access is indoor, need to adopt optical cable shown in Figure 2, this optical cable center still is a reinforcement 100, is provided with two-layer tight tube fiber 200 in that the periphery of reinforcement 100 is stranded, coat by oversheath 300 at last, that is to say that in FTTH uses need two kinds of optical cables just can finish wiring, it is cumbersome to construct, and for optical cable shown in Figure 2, it because texture material is softer, should not lay in the place that bent angle is arranged when being used for pipeline laying, simultaneously, its lateral pressure resistant ability is relatively poor, when being trampled by the people on the road surface, can influence the transmission performance of optical fiber.
Summary of the invention
The present invention seeks to provide a kind of indoor and outdoor that can be applicable to simultaneously to use and have compressive property preferably and a optical cable that can mouse bite preventing in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution used in the present invention is: a kind of full-dry high count armour indoor and outdoor optical cable, it comprises the reinforcement that is positioned at the center, mutually stranded a plurality of unit cable that is arranged on described central reinforce member periphery, is coated on the inner sheath of described a plurality of unit cable periphery, the oversheath that is sleeved on the metal armouring layer of described inner sheath periphery and is coated on described metal armouring layer periphery, and each described unit cable wrap is drawn together loose sleeve pipe, is arranged on many tight tube fibers in the loose sleeve pipe.
Further, described each unit cable also comprises the stiffener that is positioned at many tight tube fiber centers, and described many tight tube fibers mutually strandedly are arranged on the stiffener.
After tightening by aramid yarn, many tight tube fibers of each described unit cable are arranged in the described loose sleeve pipe.
Also be provided with many water blocking yarns between described inner sheath and the metal armouring layer.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage: optical cable of the present invention is owing to be provided with the metal armouring layer, make wirerope have certain lateral pressure resistant, retaining tide and mouse bite preventing performance, can be applicable to indoor and outdoor simultaneously, and, optical cable weight of the present invention is lighter, do not have liquids such as ointment, be the dry type optical cable, therefore, lay more conveniently, be convenient to continue.
Description of drawings
Accompanying drawing 1 is used for outdoor optical cable sectional view in the prior art;
Accompanying drawing 2 is used for indoor optical cable sectional view in the prior art;
Accompanying drawing 3 is the dual-purpose optical cable sectional view of indoor and outdoor of the present invention:
Wherein: 1, reinforcement; 2, unit cable; 21, loose sleeve pipe; 22, tight tube fiber; 23, stiffener; 24, aramid yarn; 3, inner sheath; 4, metal armouring layer; 5, oversheath; 6, water blocking yarn;
Embodiment
Below in conjunction with accompanying drawing, describe particular content of the present invention in detail for example:
Optical cable as shown in Figure 3, it comprises the reinforcement 1 that is positioned at the center, strandedly is arranged on a plurality of unit cable 2 of reinforcement 1 periphery, coats PVC inner sheath 3, metal armouring layer 4 and the PVC oversheath 5 that is provided with successively mutually from the inside to the outside, wherein, the aramid yarn 23 that each unit cable 2 comprises loose sleeve pipe 21, be arranged on many tight tube fibers 22 in the loose sleeve pipe 21, many tight tube fibers 22 are tightened, in order further to strengthen the intensity of optical cable, also stiffener 25 can be set at the center of each unit cable 2.
In the present embodiment, unit cable 2 has 6, and the tight tube fiber 22 in each unit cable 2 is 6, and described 6 tight tube fibers 22 can carry out different painted to show difference.
In order further to increase the block-water effect of optical cable, in the present embodiment, between inner sheath 3 and metal armouring layer 4, also be dispersed with many water blocking yarns 6.
The applicant has developed the optical cable of 48 cores at present, and the external diameter of whole optical cable only has 18.7mm, and after tested, its transmission objective and environmental index all meet the requirements, and can replace existing two kinds of optical cables that need be used fully.
To sum up, the present embodiment optical cable has following advantage:
(1), in light weight, fiber cable laying is convenient, is the dry type optical cable, does not have fouls such as ointment when continuing, and is convenient to continue;
(2), optical cable can be behind outdoor laid directly introduces indoor use, applicability is strong;
(3), owing to be provided with metal armouring layer and water blocking yarn, all have good waterproof effect at indoor and outdoors;
(4), owing to be provided with the metal armouring layer, have tension, compressive property preferably;
(5), this optical cable has the metal armouring layer, has well anti-mouse to sting function in floor.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this; can not limit protection scope of the present invention with this; all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
