Description
Technical field
The utility model relates to networking facility technology field, refers in particular to a kind of MDAS dedicated optical cable.
Background technology
MDAS(Multiservice Distributed Access System Solution), it is a kind of multi-service compartment system, Duo Jia operator can be supported, multi-modulation scheme, multicarrier, and integrated wlan system, a step solves voice and data traffic requirement, compared with traditional analog compartment system, possess mixed networking simultaneously, the feature such as low is made an uproar at delay compensation, automatically carrier track, the up end; MDAS is made up of access unit (MAU), expanding element (MEU) and far-end unit (MRU).Digitization system segmentation in MDAS has cdma system, GSM/DCS/WCDMA double-standard system, GSM/DCS/TD-SDMA double-standard system, while 2G, 3G, 4G Mobile Communication Service is provided, integrated wlan system, meets the high-rate wireless data transfer demands of user.But at present, in a lot of networking construction wiring, both having needed can the optical cable of transmitting optical signal, needing again can the power line of transmission current, and under normal conditions, optical cable and power line need to lay at twice, and efficiency of construction is low, and takies conduit resource.
Summary of the invention
The purpose of this utility model is to provide a kind of MDAS dedicated optical cable, meets optical cable and power line synchronously lays, and improve efficiency of construction and save construction cost, reasonable in design, tensile property is superior, has good mechanical performance.
For achieving the above object, the utility model adopts following technical scheme:
MDAS dedicated optical cable, this optical cable has butterfly optical cable and power line;
Butterfly optical cable oversheath internal package has fiber unit and strengthens muscle; Wrapped by band after power line and the stranded bunchy of butterfly optical cable; Band periphery has optical cable overcoat coated.
Position, space after described power line and the stranded bunchy of butterfly optical cable increases gasket for packing, the inner peripheral surface hard-pressed bale butterfly optical cable of band, power line and gasket for packing.
Described band is polyester band or nonwoven fabrics band.
The conductor of described power line is metallic conductor, and metallic conductor can be single-wire or the stranded bunchy of many wires, and conductor material can be aluminium or copper.
Described butterfly optical cable includes two and strengthens muscle, and two strengthen muscle and to be placed in the left and right sides of fiber unit, and fiber unit has 1,2 or many, and fiber unit type can be single optical fiber, fiber bundle or fibre ribbon.
Described optical cable overcoat is common polythene material or fire proofing integral production.
The MDAS dedicated optical cable that the utility model provides, its reasonable in design, optical cable and power line are organically combined, and strengthen compact siro spinning technology by auxiliary unit, meet optical cable and power line synchronously lays, improve efficiency of construction and save construction cost, tensile property is superior simultaneously, there is good mechanical performance, promote serviceability and useful life.
accompanying drawing illustrates:
Accompanying drawing 1 is the utility model one example structure schematic diagram.
embodiment:
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Consult shown in Fig. 1, the utility model is about a kind of MDAS dedicated optical cable, this optical cable circular cross-section, inside has a butterfly optical cable 1 and power line 2, butterfly optical cable 1 oversheath internal package has fiber unit 11 and strengthens muscle 12, fiber unit 11 has 1,2 or many, and fiber unit type can be single optical fiber, fiber bundle or fibre ribbon.Power line 2 includes conductor and insulating barrier, and the electric pressure of power line 2 is 400VDC; Wrapped by band 3 after power line 2 and the stranded bunchy of butterfly optical cable 1; Band 3 periphery has optical cable overcoat 4 coated.Band 3 effect prevents power line 2 and butterfly optical cable 1 from sticking together with optical cable overcoat 4, affects stripping operation, and make product have better temperature performance.
Shown in Fig. 1, the present embodiment is that the position, space after power line 2 with the stranded bunchy of butterfly optical cable 1 increases and has gasket for packing 5 further, the inner peripheral surface hard-pressed bale butterfly optical cable 1 of band 3, power line 2 and gasket for packing 5.Gasket for packing 5 is PP material plastic strips by extrusion molding, and Assisted Combinatorial strand is established, and rises and fills up structure function, guarantee the rounding property of MDAS dedicated optical cable, be also beneficial to follow-up optical cable overcoat 4 extrusion molding.Described band 3 is polyester band, and thickness is 0.05mm, and width is 19mm.The conductor of power line 2 is metallic conductor, and metallic conductor can be single-wire or the stranded bunchy of many wires, and conductor material can be aluminium or copper, and the conductor maximum resistance of further power line 2 is 18.2 Ω/km.
Shown in Fig. 1, in the present embodiment, described butterfly optical cable 1 is of a size of (2.0 ± 0.1) × (3.0 ± 0.1) mm; It is that 12, two, the enhancing muscle of 0.5mm strengthens muscle 12 and to be placed in the left and right sides of fiber unit 11 that butterfly optical cable 1 includes two external diameters, and fiber unit 11 has two to be close together side by side.Optical cable overcoat 4 is polythene material integral production, and the thickness of optical cable overcoat 4 is 1.2mm ± 0.1mm; The diameter of optical cable overcoat 4 is 7.8mm ± 0.2mm.Strengthen muscle 12 and can be metal material, as phosphating steel wire, zinc-coated wire etc.; Also can be nonmetallic materials, as FRP, KFRP, GFRP etc.
