Background technology
Optical cable is manufactured for the performance specification that meets optics, machinery or environment, and it is the communications cable assembly that utilizes one or more optical fiber that is placed in coated sheath also can use separately or in groups as transmission medium.Optical cable is mainly to protect loose sleeve pipe and plastic peel to form by light transmitting fiber (thin as the glass fiber of hair) and plastics, there is no the metal such as gold, silver, copper aluminium, generally without recovery value in optical cable.Optical cable is that the optical fiber of some forms the cable heart according to certain way, is surrounded by sheath outward, and the also coated outer jacket having, in order to realize a kind of communication line of optical signal transmission.That is: the cable being formed through certain technique by optical fiber (optical transmission carrier).The basic structure of optical cable is generally made up of several parts such as cable core, reinforcement steel wire, filling material and sheaths, also has as required in addition the members such as water barrier, cushion, insulated metal wire.Existing optical cable construction inconvenience.
Summary of the invention
For the deficiency existing in prior art, the invention provides one simple in structure, lightweight, easy construction is quick, and has reduced widely central tubular PC oil filled bushing optical fibre band optical cable of construction period and construction cost and preparation method thereof.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of central tubular PC oil filled bushing optical fibre band optical cable, comprise outer jacket, the inwall of outer jacket is coated with loose sleeve pipe, between described loose sleeve pipe and outer jacket, be filled with non-metallic fibers reinforcement material, in pine sleeve pipe, be provided with some optical fiber, between optical fiber and loose sleeve pipe, be filled with water-blocking material, some optical fiber is permutation structural arrangement; Optical fiber is three rows and four columns and arranges.
Further, the xsect of described loose sleeve pipe and outer jacket is arranged in concentric circles.
Further, described loose sleeve pipe is PC pine sleeve pipe, and described PC pine sleeve pipe is tubular structure.
Further, described outer jacket is low smoke and zero halogen outer jacket; Described low smoke and zero halogen outer jacket tubular structure.
Further, described optical fiber is three rows and four columns layout.Described non-metallic fibers reinforcement material is aramid yarn, high carbon fiber yarn or thermosetting glass fiber yarn.
A kind of method for making of above-mentioned central tubular PC oil filled bushing optical fibre band optical cable, its method: first fibre ribbon is moulded to technique by cover and be extruded onto into loose sleeve pipe, in pine sleeve pipe, fill water-blocking material, and then be extruded onto again black low smoke and zero halogen material by extruding machine in pine cover tube outside, be secondary extrusion process, form outer jacket.
Beneficial effect:
The central tubular PC oil filled bushing optical fibre band optical cable of employing technique scheme of the present invention, owing to being filled with aramid fiber between described loose sleeve pipe and outer jacket, in pine sleeve pipe, be provided with some optical fiber, between optical fiber and loose sleeve pipe, be filled with water-blocking material, some optical fiber is permutation structural arrangement; Optical fiber is three rows and four columns and arranges, so simple in structure, lightweight, easy construction is quick, realizes the remaining long control of loose sleeve pipe inner fiber secondary, can realize again the requirement of this optical cable mechanical property such as required high wall pressure, high strength and environment for use and temperature performance when laying; The heatproof of optical cable requires to reach-30 DEG C-+70 DEG C, allows flat pressure to reach 500N/10cm; Construction period and construction cost are reduced greatly, for the development of Access Network provides a kind of brand-new solution.
Brief description of the drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of central tubular PC oil filled bushing optical fibre band optical cable of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
As shown in Figure 1, a kind of central tubular PC oil filled bushing optical fibre band optical cable, comprise outer jacket 5, the inwall of outer jacket 5 is coated with loose sleeve pipe 3, between pine sleeve pipe 3 and outer jacket 5, be filled with aramid yarn 4, in pine sleeve pipe 3, be provided with some optical fiber 1, between optical fiber 1 and loose sleeve pipe 3, be filled with water-blocking material 2, some optical fiber 1 is permutation structural arrangement; Optical fiber 1 is three rows and four columns and arranges; Pine sleeve pipe 3 is arranged in concentric circles with the xsect of outer jacket 5, and loose sleeve pipe 3 is tubular structure, and outer jacket 5 is tubular structure.
Central tubular PC oil filled bushing optical fibre band optical cable of the present invention, adopts central tubular structure, and namely whole cable only has a loose sleeve pipe, and adopts PC(polycarbonate; Polycarbonate) loose sleeve pipe and band structure of optic fibre design and novel technology controlling and process, not only can well solve the remaining long problem of loose sleeve pipe inner fiber, but also can solve cable outer diameter thick, from problems such as great and construction inconvenience, mould the high lateral pressure resistant that technique realizes optical cable and stablize suitable remaining long control by the agent of loose sleeve pipe secondary; First fibre ribbon is moulded to technique by cover and be extruded onto into certain thickness loose sleeve pipe, in loose sleeve pipe, fill water-blocking material, and then be extruded onto again certain thickness black LSZH(LowSmokeZeroHalogen by extruding machine in pine cover tube outside; Low smoke and zero halogen) material, secondary extrusion process forms outer jacket 5.
