Abstract
The invention relates to an optical cable leading in house from outdoors. The inner part of the cable is provided with butterfly rubber-insulated cables, and one or two optical fibers are arranged between the butterfly rubber-insulated cables; the two sides of the optical fiber are respectively provided with a small glass fiber reinforcing bar; the optical fibers and the small glass fiber reinforcing bars are fixed in a butterfly module made of flame retardant polyolefin so as to form the butterfly rubber-insulated cable; the two sides of the butterfly rubber-insulated cable are respectively provided with a big glass fiber reinforcing bar; the butterfly rubber-insulated cable and the big glass fiber reinforcing bars are coated together by a longitudinally-covered waterproof tape; and the longitudinally-covered waterproof tape is coated with a layer of intermediate-density polyethylene protection sleeve. The optical cable has the advantages that: the optical cable leading in house from outdoors and the indoor optical cable share the same butterfly rubber-insulated cable, so the indoor cable laying can be realized only by stripping off the protection sleeve of the optical cable leading in house from outdoors without cutting off the butterfly optical cable therein, which avoids the trouble of connecting the optical fiber and improves the reliability of optical fiber transmission.
Description
Technical field:
The present invention relates to a kind of optical cable leading in house from outdoors.
Background technology:
What the outdoor leading in cable of present user of access network was used all is the elastic sleeve tube type optical cable, this kind optical cable is because optical fiber places the terephthalate (PBT) engineering plastic pipe that is full of ointment, not only total external diameter of optical cable greatly, not flexible, and owing to needing to remove earlier ointment, troublesome poeration before ointment contaminated environment, the fibre junction.After traditional elastic sleeve tube type optical cable arrival user is indoor, need cut-off optical cable and optical fiber, connect indoor rubber-insulated wire flexible optical cable and optical fiber with cable junction box, a plurality of fibre-optical splices can increase the Optical Fiber Transmission decay, influence transmission performance.
Summary of the invention:
In order to solve the problems of the technologies described above, the invention provides a kind of optical cable leading in house from outdoors.
The technical solution adopted for the present invention to solve the technical problems is: a kind of optical cable leading in house from outdoors, the bosom position is the butterfly covered wire cable, be provided with 1 or 2 optical fiber in the described butterfly covered wire cable, the both sides of optical fiber is respectively equipped with small size glass fibre reinforcement, described optical fiber and small size glass fibre reinforcement are fixed on the butterfly covered wire cable that fire retardant polyolefin is made, described butterfly covered wire cable both sides are respectively arranged with large size glass fibre reinforcement, described butterfly covered wire cable and large size glass fibre reinforcement are always coated by the medium density polyethylene sheath by vertical bag waterstop parcel again.
Concrete:
Described optical fiber is optical fiber G.657A.
The diameter of described small size glass fibre reinforcement is 0.5mm.
The diameter of described large size glass fibre reinforcement is 1mm.
The thickness of described medium density polyethylene sheath is 0.6mm～0.8mm.
The invention has the beneficial effects as follows: make outdoor optical cable and same covered wire cable cable core of inside cable use of registering one's residence, optical cable need not be cut-off in the centre, has removed the trouble of fibre junction from, has improved the reliability of Optical Fiber Transmission.
Description of drawings:
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1, optical fiber; 2, small size glass fibre reinforcement; 3, butterfly covered wire cable; 4, large size glass fibre reinforcement; 5, vertical bag waterstop; 6, medium density polyethylene sheath.
Embodiment:
A kind of as shown in drawings optical cable leading in house from outdoors, bosom position are provided with 1 or 2 optical fiber 1, and the both sides of optical fiber 1 is respectively equipped with the small size glass fibre reinforcement 2 of Φ 0.5mm, are used for the anti-pressure ability of rubber-insulated wire cable core.Described optical fiber 1 and small size glass fibre reinforcement 2 usefulness fire retardant polyolefins are extruded into one, form the butterfly covered wire cable, and this kind optical cable can lay along wall in that the user is indoor, but can't be as outdoor leading in cable.For this butterfly covered wire cable 3 is extended to outdoor application, be respectively arranged with large size glass fibre reinforcement 4 in described butterfly covered wire cable 3 both sides, described butterfly covered wire cable piece 3 and large size glass fibre reinforcement 4 are coated togather by vertical bag waterstop 5, and described overall budget waterstop 5 outsides are provided with one deck medium density polyethylene (MDPE) sheath 6.
During use, can make somebody a mere figurehead and lay or lay by user's underground pipeline, can peel off oversheath 6 after entering the user house, behind large size glass fibre reinforcement 4 cable junction box on the wall, butterfly rubber-insulated wire cable core can continue to lay the optical information socket that arrives the user along wall in that the user is indoor, and optical cable need not be cut-off in the centre.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
