Abstract
The utility model relates to a circular branch optical cable. The cable comprises a pair of single-core optical cables, a filling cable and a protection sleeve that is coated on the single-core optical cables and the filling cable. Each single-core optical cable comprises a fiber core, aramid yarn coated on the fiber core and a leather layer coated on the aramid yarn. The cable can be connected with a branch cable without the whole cable cut, so that cable connectors are reduced with more convenient construction. Since the number of the cable connectors is reduced, failure rate of the cable lines is greatly reduced and reliability of the cable lines is improved.
Description
Technical field
The utility model relates to a kind of circular branched cable.
Background technology
Development along with communication industry, 3G and FTTH start, and the pace of construction of City Access Network is being accelerated, and the access point of optical fiber access is more and more closeer, short distance multiple-limb situation can be more and more in City Access Network, and this just needs optical cable enterprise to consider that research and development adapt to the Novel optical cable of network Development.The application of branched cable in Access Network further developing along with optical communication, the emphasis of the communication network development has been transferred to City Access Network, comprise the construction of 3G, FTTH, catv network, in the construction of these networks along with the increase of cloth reticular density, the optical cable tapping point can be more and more closeer, the short distance multiple-limb is essential, and the application of branched cable and popularization will be played the part of more next important role in the construction of these networks.Differently on 3G network and the 2G network organizing be, the higher area of information flow-rate density particularly in the city, the network coverage radius of base station is less, usually less than 600m, some in addition only have 200m, select branched cable to be undoubtedly preferred version in these zones from the optical fiber incision that exchanges to each base station.For the FTTH network, the density of network is maximum, no matter be that outdoor optical cable is to the residential quarter, to the building, or inside cable Fiber to the home, fiber to the desk, the density of fiber cable branch is well imagined, in this network, use branched cable more superior, can reduce a large amount of fiber cable joints, thereby greatly reduce the fault of being brought by the cable connection point, effectively improve the reliability of network.
Summary of the invention
The purpose of this utility model is to provide a kind of circular branched cable.
The technical scheme that the utility model adopts is: a kind of circular branched cable, it comprises: at least one pair of single fiber cable, fills cable, with single fiber cable with fill the sheath that cable coats, and wherein single fiber cable comprises fibre core, is coated on the aramid yarn around the fibre core and is coated on cortex around the aramid yarn.
Preferably, its diameter is 8-12mm, and the diameter of single fiber cable 10 is at 2-4mm, and described single fiber cable is even number simultaneously.
The cortex of described different single fiber cables has different colours to indicate.
The bending radius of described fibre core is at 4-8mm.
Described sheath is that cable core comprises the compound inner sheath of steel-tygon.
The beneficial effects of the utility model are: simple in structure, manufacture easily; Branch is convenient, need not cut off or cut optical cable, saving of work and time, and the damage to optical cable integral body is few, can avoid improving fiber cable laying and engineering construction quality because fibre-optical splice increases sending allowance and issuable trouble spot, guarantee that the Stability and veracity reduction of optical cable information transmission is convenient; After adopting the multilayer set-up mode, can utilize the dimensional space of machine extruder head, increase message capacity.Branched cable also has following characteristics simultaneously:
1, the branched optical fiber cable product can be told sub-optical cable as required at the tapping point of network.
2, multiple interrupted incision segregant optical cable easily on the branched cable.
3, the tap place of optical cable does not need to carry out the cutover of whole optical cable, has reduced fiber cable joint, constructs more convenient.Owing to having reduced fiber cable joint quantity, the line fault incidence of optical cable greatly reduces, and has improved the reliability of lightguide cable link.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is inner structure schematic diagram of the present utility model.
Fig. 2 is schematic perspective view of the present utility model.
Embodiment
Embodiment: shown in Fig. 1-2, the utility model provides a kind of specific embodiment of circular branched cable, it comprise at least one pair of single fiber cable 10, fill cable 20, with single fiber cable 10 with fill the sheath 30 that cable 20 coats, wherein single fiber cable 10 comprises fibre core 100, is coated on the aramid yarn 102 around the fibre core 100 and is coated on cortex 104 around the aramid yarn 102.Wherein single fiber cable 10 is preferably even number, i.e. 2 cores or 4 cores or 8 cores; The diameter of single fiber cable 10 is preferably at 2-4mm, and the diameter of whole circular branched cable is preferably at 8-12mm.Wherein cortex 104 colors of different single fiber cables 10 are different, in order to distinguish.The bending radius of fibre core 100 is at 4-8mm.Sheath 30 comprises the compound inner sheath of steel-tygon for cable core, its optical cable anticorrosion effect is good, anti-Zhang Nengli or impact resistance all improve a lot than common chromium plating composite steel band and stainless steel band, from intensity relatively, the surrender of special protection against rodents composite steel band is measured by force and has been improved 20%, to greatly improve so the anti-damaged by rats of optical cable impacts and the ability that bites, fibre strain is no more than 0.10% under the short-term tension force that optical cable is set, adopt the optical cable of protection against rodents structure can satisfy the performance requirement that lays and move by test and factory inspection proof, its every test figure all is better than the requirement of national standard, good temperature characterisitic and rodent-proof characteristic are arranged simultaneously, can promote the use of on a large scale.
The utility model does not need to carry out the cutover of whole optical cable at the tap place of optical cable, reduced fiber cable joint, constructs more convenient.Owing to having reduced fiber cable joint quantity, the line fault incidence of optical cable greatly reduces, and has improved the reliability of lightguide cable link.
