Abstract
The utility model relates to an indoor and outdoor dual-use optical cable, which comprises a cable core and a flame-resistance inner protection jacket wrapping the cable core, the utility model is characterized in that the flame-resistance inner protection jacket is provided with a water stop layer which is wrapped with metal band which is wrapped with outer protection jacket, the said cable core is the center beam tube optical cable core or loose tube layer stranded optical cable core. The utility model has the following advantages: 1. The utility model has good water-stop effect, and excellent flame-resistance property, and good tensile strength. The outer protection jacket has ability of UV resistance and can meet the requirements of indoor and outdoor optical cable laying. 2. When the optical cable is brought into room from the outside, the utility model is not necessary to perform the segmented connection, and only outer protection jacket and metal band are to be stripped and the flame-resistance inner protection jacket is exposed, and then the optical cable directly is connected into the room for branch connection, so that the utility model not only simplify the laying construction of optical cable to reduce the laying cost of optical cable but also enforce the reliability of the system.
Description
Technical field
The utility model relates to a kind ofly can be used for the indoor dual-purpose optical cable of indoor and outdoor that can satisfy the outdoor laid environmental requirement again.
Background technology
Different environments for use and laid condition have proposed different requirements to the performance of optical cable: inside cable requires that the good flame performance is arranged, and outdoor optical cable not only will have good block-water effect, and its sheath should have good anti-uv-ray.In present prior art, inside cable and outdoor optical cable are that segmentation is used, and the centre will be abutted against head and be connected, the uncontinuity of joint and be connected the reliability that stress can reduce system, the increase maintenance cost.Continuous development along with Fiber to the home networking, the demand of optical cable that enters residential quarters, building, room is increasing, therefore, carry out networking if still continue to use traditional optical cable, above-mentioned joint can increase undoubtedly greatly, this makes troubles not only for the cable laying operation of optical cable, and can influence the reliability of total system.Therefore, pressing for exploitation a kind of can being used for indoorly can be used for outdoor optical cable again.
Summary of the invention
Technical problem to be solved in the utility model be the deficiency that exists at above-mentioned prior art and provide a kind of can satisfy simultaneously indoor and outdoor lay environmental requirement, can be from the dual-purpose optical cable of indoor and outdoor of the indoor use of outdoor direct access.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is as follows: the fire-retardant inner sheath 5 that includes cable core and coating cable core, its difference is to be provided with water blocking layer 6 outside fire-retardant inner sheath, the vertical outward bag metal tape 7 of water blocking layer, metal tape coats oversheath 8 outward.
Press such scheme, described cable core is the central beam tube type optical cable core, or the loose sleeve layer strand type optical cable core; Described water blocking layer is made of waterstop or water blocking yarn; Described metal tape is overlay film aluminium strip or steel band; Described oversheath is the PE oversheath, has good anti-uv-ray.
The beneficial effects of the utility model are: 1, existing good block-water effect, and have good flame retardant property again, and possess better tensile strength, and oversheath has the ultraviolet ability of opposing, can satisfy the indoor and outdoor optical cable simultaneously and use the requirement lay; 2, when optical cable is indoor from outdoor introducing, need not to carry out sectionalizing joint connects, as long as peel off oversheath, metal tape and water blocking layer, exposing fire-retardant inner sheath can directly insert indoor, carrying out difference continues, this has not only simplified the cable laying operation of optical cable greatly, reduces the laid down cost of optical cable, and has strengthened the reliability of system.
Description of drawings
Fig. 1 is the radial section figure of an embodiment of the utility model.
Fig. 2 is the radial section figure of another embodiment of the utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
First embodiment is a kind of central beam tube type optical cable as shown in Figure 1, and its cable core comprises loose sleeve pipe 3, include the fine cream 2 of optical fiber 1 and filling in the pine sleeve pipe, be used to block water, loose sleeve pipe lays fiber reinforcement 4 outward, the fiber reinforcement is aramid yarn or glass fibre, constitutes cable core thus; The fire-retardant inner sheath 5 of the outer coating of cable core, fire-retardant inner sheath is made by bittern-free flame-proof material; Be provided with water blocking layer 6 outside fire-retardant inner sheath, water blocking layer is made of waterstop or water blocking yarn; The vertical outward bag metal tape 7 of water blocking layer, metal tape is the overlay film aluminium strip, and metal tape coats oversheath 8 outward, and the oversheath that oversheath is made for the PE material has good anti-uv-ray.In addition, in the metal tape clad, can be provided with and tear rope 10 so that metal tape and oversheath open stripping.Whole optical cable can use in outdoor occasion and lay, and in the time of in optical cable is wanted inlet chamber, the oversheath and the metal tape of optical cable is peelled off with tearing rope, just can be used as inside cable and uses.Fiber reinforcing element in the optical cable can guarantee that optical cable has certain tensile strength, and water blocking layer can guarantee that optical cable has good block-water performance.Fire-retardant inner sheath can satisfy the fire-retardant requirement of optical cable when indoor use, and the PE oversheath has good anti-uv-ray, and the metal tape in the optical cable also has good damp proof insulation effect.
Second embodiment as shown in Figure 2, be the loose sleeve layer strand type optical cable, cable core comprises central reinforce member 9, and central reinforce member can be nonmetal central reinforce member, and the outside is provided with water blocking layer 6, at the periphery of the central reinforce member loose sleeve pipe 3 that tangled, jacketed fiber 1 and be filled with fine cream 2 in the pine sleeve pipe, loose sleeve pipe can be provided with 3～6, and loose sleeve pipe is provided with water blocking layer 6 outward, water blocking layer is made of waterstop or water blocking yarn, constitutes cable core thus; Clad structure outside the cable core is identical with a last embodiment, is coated by fire-retardant inner sheath 5, water blocking layer 6, metal tape 7 and oversheath 8 successively to form, and is provided with in the metal tape clad and tears rope 10.Present embodiment is suitable for the bigger occasion of fiber number to be used.
