Description
Technical field
The utility model relates to the Optical Fiber Composite cable, relates in particular to mounted Optical Fiber Composite cable behind a kind of optical fiber.
Background technology
Fiber composite power cable is the complex of optical cable and cable, and it can lay fiber optic network along with the cable power supply circuit network, has the optical signal transmission of optical cable and the electric power transfer function of cable simultaneously, has realized the integrated of flow of power, information flow and Business Stream.Owing to avoided the wiring that repeats of cable and optical cable, also can significantly reduce the networking expense.
The basic structure of existing Optical Fiber Composite low-voltage cable (OPLC) is that the conductor thread cores such as copper, aluminium or copper cover aluminum of various types of micro optical cables and insulation is synchronously stranded as cable core, extrude cable cover(ing) more outside, so conductor in the insulated wire cores and the optical fiber in the micro optical cable are equal lengths.But in actual applications, conductor is directly connected to the receiving end mouth, and optical fiber then needs to reserve 1 meter length at least and goes to link with optical port or with tail optical fiber, so can only be with the conductor amputation.That is to say that the every receiving end mouth of Optical Fiber Composite cable will lose the conductor of at least 1 meter length, cause the very big waste of conductor resource virtually.
When the sectional area of conductor was big, the diameter of Optical Fiber Composite cable and deadweight also increased thereupon, and because of deadweight will make the elongation of cable body, the optical fiber in the cable will be yielded to the cable body and elongation synchronously in construction.Conductor material such as copper, aluminium is because of having bigger elongation so influence electric conductivity and working life hardly, and the permission tensile deformation amount of optical fiber is very little, transmission attenuation just begins to increase when its strain reaches 0.3%, surpasses 0.4% o'clock optical fiber as strain and just might rupture.So especially the Optical Fiber Composite cable that cross-sectional area of conductor is long-pending bigger causes optic fibre force hidden danger easily when construction, cause the optical fiber life-span to descend or the decay increase.Therefore, should provide a kind of new technical scheme to address the above problem.
The utility model content
The purpose of this utility model is: must clip the waste of conductor and optical fiber when overcoming the construction and installation of existing fiber composite cable because of conductor and optical fiber are isometric and yield to the conductor elongation and cause the deficiency that the optical fiber life-span descends or decay increases, propose installing type Optical Fiber Composite cable behind a kind of optical fiber.
For achieving the above object, the technical solution adopted in the utility model is:
Installing type Optical Fiber Composite cable behind the optical fiber; comprise cable core and the cable cover(ing) that is coated on the cable core outer surface; described cable core comprises the insulation conductor wire core; described cable core also comprises the hollow optic fibre protection tube; described hollow optic fibre protection tube is twisted into one synchronously with the insulation conductor wire core, is mounted with optical fiber in the hollow optic fibre protection tube of installing type Optical Fiber Composite cable laying after good behind optical fiber.
Be provided with the optical fiber pull rope in the described hollow optic fibre protection tube.
Described hollow optic fibre protection tube is that high density polyethylene (HDPE) blank pipe or silicon are moulded compound blank pipe, and the quantity of described hollow optic fibre protection tube is 1 or many.
Described optical fiber is high-performance optical fiber unit or micro optical cable.
The utility model; the hollow protection tube of moulding compound blank pipe or other suitable materials with high density polyethylene (HDPE) blank pipe, the silicon of the insulation conductor wire core such as copper, aluminium or copper cover aluminum of insulation and suitable diameter is synchronous stranded as cable core, and extruding cable cover(ing) more outside becomes the composite rope that contains the fiber optic protection blank pipe.Behind this composite rope cable laying operation, in hollow optical fiber protective tube, high-performance optical fiber unit or micro optical cable are installed with air-blowing or tractive method, become last Optical Fiber Composite cable.The restriction that high-performance optical fiber unit that install the back or micro optical cable length are not subjected to conductor length can have more desired random length than conductor length, thereby avoid clipping the waste of conductor; Because of when construction the cable inner wire and protection tube all oneself has passed through pre-stretching, the strain of cable body elongation when the high-performance optical fiber unit that install the back or little cable can not be subjected to constructing, thus avoided optic fibre force to cause decaying increasing and the hidden danger of life-span decline.Another remarkable advantage is, can have many hollow protection tubes in the composite rope, can carry out the installation of cable power supply system in advance before the fiber optic network construction, and then according to the requirement of Optical Access Network system optical fiber is installed flexibly; In addition, in case optical fiber breaks down or fibre system upgrading (fiber number or fiber type change as required), can be under the situation that does not influence cable power supply independent maintenance or change high property fiber unit or micro optical cable, thereby have greater flexibility.
