Description
Technical field
The utility model relates to optical cable art, refers in particular to a kind of central beam tube type communication optical cable.
Background technology
The cable core that communications optical cable (Communication Optical Fiber Cable) is made up of some (core) optical fiber (generally from a few core to several thousand cores) and outer jacket formed.Optical fiber is compared with traditional symmetrical copper loop and coaxial copper loop, and its transmission capacity is much bigger; Attenuation is few; Transmission range is long; Volume is little; Lightweight; Cost is low, is the most promising current communications media.It is just being widely used for, on the Signal transmissions of all departments such as telecommunications, electric power, broadcast, progressively becoming the main body of future communications network.Structurally main with the cable difference of communications optical cable is that optical cable must have reinforcement to go to bear extraneous mechanical load, to protect optical fiber from the impact of various outer mechanical force.
The communications optical cable such as occasion, request for utilization according to using is divided into polytype, as central beam tube type, loose sleeve layer strand type, self-bearing type etc.But, its profile of current central beam tube type communication optical cable is generally circle, good location and installation can not be realized with outside, and only support by two cylindrical reinforcements, extraneous mechanical load can not be born well, meanwhile, current central beam tube type communication optical cable also exists easily is broken by the teeth by animal or suffers people for malicious sabotage.On the whole, also there is the not good enough problem of usability in current central beam tube type communication optical cable, is necessary to make improvements.
Utility model content
In view of this, the utility model is for the disappearance of prior art existence, and its fundamental purpose is to provide a kind of central beam tube type communication optical cable, and it effectively can solve existing central beam tube type communication optical cable and there is the not good problem of usability.
For achieving the above object, the utility model adopts following technical scheme:
A kind of central beam tube type communication optical cable, include Loose tube, multifiber is provided with in this Loose tube, optical fiber ointment is filled with in each cavity between optical fiber and Loose tube, the lateral surface of this Loose tube is enclosed with waterstop, the lateral surface of this waterstop is enclosed with two-sided covering and moulds wrinkle steel band, this two-sided lateral surface armouring moulding wrinkle steel band that covers has one week arch FRP layer, outer protective polyethylene cover has been extruded outside arch FRP layer, all sides of this outer protective polyethylene cover are formed with four arc grooves and four arc convex, four arc grooves and four arc convex replace all circles one by one and arrange, a metal reinforcement is provided with in each arc convex, the xsect of this metal reinforcement is triangle, and the outside surface of this outer protective polyethylene cover is also coated with weathering layer.
As a kind of preferred version, described optical fiber is colored optical fiber, and the quantity of optical fiber is 2 ~ 24.
As a kind of preferred version, the quantity of described optical fiber is 8.
As a kind of preferred version, between described multifiber, compartment of terrain is bonded with cured resin.
As a kind of preferred version, described arch FRP layer is the six roots of sensation that Zhou Yuan is intervally arranged, the gap filling tygon between adjacent two arch FRP layers.
The utility model compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution:
Four arc grooves and four arc convex are formed by all sides overlapped at outer protective polyethylene, good location and installation can be realized with outside to make this product, and more economize material, simultaneously, a metal reinforcement is equipped with in each arc convex, the xsect of complexed metal reinforcement is triangle, extraneous mechanical load can be born better to make this product, and, by having one week arch FRP layer at the two-sided lateral surface armouring moulding wrinkle steel band that covers, to be broken by the teeth by animal to avoid this product or suffer people for malicious sabotage, and good weatherability, the usability of product is significantly enhanced.
For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.
