Description
Technical field
The present invention relates to a kind of optoelectronic composite cable, particularly a kind of multi-core optical photoelectric compound cable.
Background technology
Along with the development of communication industry, communication network from single speech business to voice, the full-service integrated communication direction message development of data, video several data business, the construction of optical-fiber network is from backbone network, core net to metropolitan area network, Access Network development.And because still there are many covering problems in the cause of operating frequency.Remote radio efficiently solves because many covering problems that the low cause of operating frequency causes as a kind of novel distributed network replace mode.But the cable that is used for the remote radio of base station, need simultaneously transmitting optical signal and electric power, and traditional solution is to lay respectively as the optical cable of optical signal transmission with as the cable of electric power transfer, this not only brings difficulty to construction, use and construction cost have also been increased, and because the diameter of optical cable is less, tensile strength is lower, lays very easily separately and breaks.
Chinese patent application number: 201020655801.9 disclose a kind of central tube-type optic/electric composite cable, water blocking layer is arranged between loose sleeve pipe and the composite steel-plastic belt, and copper conductor is arranged on oversheath inside, such structure is so that the waterproof of composite rope only is confined to fiber section, and the part of electric power transfer can't guarantee, this brings no small potential safety hazard to electric power transfer undoubtedly.
Chinese patent application number: 201220363366.1 disclose a kind of photoelectricity mixing ripple cable; comprise optical communication element, communication unit and oversheath; this optical communication element comprises at least one pair of fiber cores; this communication unit comprises at least one electronic communication link; its carrying of the ripple cable of this structure and resistance to tension are poor; the cable major part is exposed in the extraneous air, and after through long-term exposing to the sun and rain, the protective effect that the outer jacket of cable plays is little.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide that a kind of block-water performance is good, tensile strength is high, easy construction and the low multi-core optical photoelectric compound cable of cost of manufacture, light harvesting is fine, the transmission of electricity copper cash is in one, simultaneously transmitting optical signal and electric power.
Purpose of the present invention is achieved through the following technical solutions: a kind of multi-core optical photoelectric compound cable, it comprises oversheath, central reinforce member, tight tube fiber, electric lead, waterstop and fills out core, oversheath is the cylindrical structure of hollow, the coaxial center that is arranged at oversheath of central reinforce member, many tight tube fibers, electric leads and fill out core and be arranged between oversheath and the central reinforce member, the outer setting of every tight tube fiber has reinforcement and subelement sheath, and tight tube fiber, electric lead and the appearance of filling out core are coated with waterstop.
Described electric lead has three, and every electric lead is to be closed by multiply fine copper skein silk to form.
The external diameter scope of described oversheath is Φ 11.4mm～Φ 11.8mm.
Described tight tube fiber has four, and the reinforcement of every tight tube fiber outer setting is the aramid fiber reinforced layer.
Described oversheath is made by fire retardant polyolefin.
The present invention has the following advantages:
1, be wrapped with waterstop at optical fiber and electric lead skin, can effectively stop moisture to infiltrate, and oversheath also has certain block-water effect, its integrated water stop performance is good.
2, be provided with middle reinforcement in the center of composite rope, in the tight tube fiber outer setting reinforcement is arranged, and outermost oversheath all strengthened carrying and the tensile property of composite rope.
3, tight tube fiber and electric lead are combined with each other, do not need again respectively laying optical cable and cable, reduce difficulty of construction and operating expenses, decrease wiring workman's labour intensity, easy construction.
4, tight tube fiber and electric lead are combined with each other, have saved the structure except optical cable core and cable core, the cost of manufacture decrease.
