Under the background of " light advances copper and moves back " and energy-saving and emission-reduction, radio reception device is released the fiber optic stretch solution: promptly use baseband processing unit BBU (Base Band Unit) and far-end masthead units RRU (Radio Remote Unit) in the optical cable junction chamber, only need the optical cable that the core number is more, just can support a plurality of RRU, significantly reduce optical cable laying construction working amount, also accelerated the speed of building a station simultaneously; Can realize that a plurality of BBU share a machine room, the shared multifiber cable of a plurality of near-end machines makes base station selection more flexible, but also can reduce support equipment cost, construction cost and the operation expense of base station greatly; Be easy to branch midway, can simplify the network planning greatly; It is convenient to continue, and is easy to the follow-up network optimization and dilatation.
In the fiber optic stretch solution, to the new requirement of connection proposition of equipment room, the physical characteristics of indoor cable is arranged promptly, also to satisfy the requirement of outdoor application.
The cable configuration that uses in the machine room be single core, twin-core cable substantially, structural limitations application, can only be in indoor use, as using distribution or optical fiber cable for field operation, cost is unusual costliness again.
Summary of the invention:
The purpose that the utility model solves provides a kind of fire-retardant armouring wire jumper, is the dual-purpose optical cable of indoor and outdoor, can better meet the practicality of optical cable, reduces cost.Fire-retardant armouring jumper wire construction comprises outdoor optical cable, optical fiber, loose sleeve pipe, heat-shrink tube, stainless steel armored hose, FC joint, it is characterized in that: outdoor optical cable is contained in the preceding web member 5, preceding web member 5 is connected with rear connectors 6 usefulness reinforcements, the sleeve pipe inner fiber 4 that is connected with preceding web member 5, passing rear connectors 6 is connected with FC joint 10, optical fiber is with the stainless steel armored hose outward, is with heat-shrink tube 8 at preceding web member 5 and rear connectors 6 outsides, and reinforcement is fixed with jackscrew.Stainless steel armored hose 9 is made of from outside to inside PVC restrictive coating 11, wire sheathing 12, aramid fiber enhancement Layer 13, stainless steel ripple 14.
The utility model has the advantages that:
1, reduces ground, base station support equipment cost, construction cost and operation expense greatly;
2, anti-ultraviolet aging;
3, tension, wear-resistant and lateral pressure resistant, softness are fit to little space;
4, anti-thunder and lightning; Satisfy the requirement of house wiring:
5, be easy to branch midway, it is convenient to continue, and is easy to the network optimization and dilatation, shortens the engineering time, saves executive cost;
6, the optical cable support vertically lays, can use anti-little curved G.657A/B, optical fiber G.652, guaranteed the requirement of house wiring;
7, safety, fire-retardant.
8, equipment end socket is selected international standards such as joint FC/SC/ST/MU/LC/E2000 for use.

Among the figure, 1 is outdoor optical cable, and 2 is reinforcement, 3 is loose sleeve pipe, and 4 is optical fiber, and 5 is preceding web member, 6 is rear connectors, and 7 is jackscrew, and 8 is heat-shrink tube, 9 is the stainless steel armored hose, 10 is FC joint (replaceable), and 11 is the PVC sheath, and 12 is wire sheathing, 13 is the aramid fiber enhancement Layer, and 14 is the stainless steel ripple.
Embodiment:
Fire-retardant armouring wire jumper optical cable in the utility model, its structure comprises: outdoor optical cable, optical fiber, loose sleeve pipe, heat-shrink tube, stainless steel armored hose, FC joint, outdoor optical cable 1 is contained in the preceding web member 5, can fix with glue, preceding web member 5 is connected with rear connectors 6 usefulness reinforcements 2, pass rear connectors 6 with optical fiber 4 in preceding web member 5 joint sleeves 3 and is connected with FC joint 10, the optical fiber 4 outer stainless steel armored hoses 9 that are with wrap up at preceding web member 5 and rear connectors 6 outsides cover employing heat-shrink tube 8.Reinforcement 2 usefulness jackscrews 7 are fixing.Optical cable manufacturer according to port, the length of customer requirement, makes corresponding connecting line finished product, direct access device, and convenient construction, the step that simplifies the operation promptly shortens the engineering time, can reduce the cost of building a station again.
This product is selected layer-twisted type structure production technology for use:
1, once lining
Optical fiber coloring is meant at the true qualities optical fiber surface and coats printing ink and make it to keep a process than strong adhesive force through overcuring.It requires the color clear of colored optical fiber easily to distinguish, and the color layers difficult drop-off is good or the like with the ointment compatibility.Come branch can be divided into two kinds by curing mode, heat curing and ultraviolet light (UV) solidify, and along with the development of optical cable manufacturing, UV curing is fast with speed of production, efficient is high, solidify the mode that the excellent characteristics of quality have progressively replaced heat curing.
After coloring process finishes, to comprehensively detect, the solidification effect of its color is arranged painted back optical fiber, and product transmission performance length or the like.
2, secondary coated
Pine cover technology is the outside surface at colored optical fiber, extruded the certain thickness pine cover of certain diameter buffering plastic tube again, and filled fine cream, promptly primary coating fibre can move freely in pine cover buffering plastic tube, be filled with the petroleum jelly that blocks water in the pine sleeve pipe, for secondary coated.
3, stranding
Optical fiber cabling is exactly according to the stranded process of making layer-twisted type structure optical cable core of certain rule with elements such as some loose tube fibers and reinforcements.The stranding purpose is for obtaining the Stability Analysis of Structures optical cable core, make that optical cable has excellent mechanical properties and temperature characterisitics such as better tension, resistance to compression, bending resistance, antitorque commentaries on classics, shock resistance after sheath extrudes, and has a minimum geometric volume, improve simultaneously because of external force causes optical fiber micro-bending and variation of ambient temperature and cause compressive strain, keep the intrinsic good transport property of optical fiber.
4, sheath
For not being subjected to that extraneous machinery, thermochemistry, moisture and biosome bite etc., cable core behind the protection optical fiber cabling do not influence; must there be sheath the optical cable core outside; even the oversheath protection is arranged, only in this way just can more effective protection cable optical fiber operate as normal and requirement in serviceable life.
5, make connecting line
By hand finished cable sheath epidermis is peeled off, penetrate web member 5, peel loose sleeve pipe off and expose optical fiber 4, the web member 6 of again stainless steel flexible hose being packed into, optical fiber 4 is penetrated in the stainless steel flexible hose, web member 5 is connected with web member 6, play glue and fix, with heat-shrink tube web member 5 and web member 6 are wrapped up, at last the wire wrappings that will be scattered with plastic spiral pipe.
Use the purpose of this web member 5, web member 6 to be, protection joint optical fiber.
6, optical fiber lapping
According to customer requirement, select corresponding joint for use.
