Description
Technical field
The present invention relates to the fiber box of a kind of OPLC (OpticalFiber Composite Low-voltage Cable optical fiber composite low-voltage cable) usefulness.
Background technology
In recent years, along with the development of intelligent grid, State Grid Corporation of China proposed the concept of " four nets merge ", and namely electrical network, telecommunications network, Broadcasting Cable Network, internet organically blend.Because OPLC has merged the function of optical fiber communication and electric power transfer, compare the simple function transmission cable, it has that high reliability data transmission, price are low, easy to connect, optical cable and line of electric force need not the characteristics such as secondary wiring in one, therefore select OPLC to realize that Fiber to the home, solve lightguide cable link duplicate construction investment problem, reduce " black pollution ".And as the important access device that connects user and network, in the technology that fiber box is applied in more and more widely that Fiber to the home, it is applicable to optical cable and is connected with the distribution of optical communication equipment, by the adapter in the distributing cabinet, draw light signal with the wire jumper tail optical fiber, the function that realizes that Fiber to the home.Be applicable to optical cable and be connected protectiveness with the distribution tail optical fiber and connect, also be applicable to the fibre-optic terminus point employing in the Optical Access Network.
Fiber box of the prior art mainly contains following two classes:
(1) operator's distributing cabinet, layout only is equipped with the device of telecommunication service access in its space, the function that namely only possesses the telecommunication service access, and in order to satisfy to greatest extent the client, each operator all can plan according to the maximum number of user amount fiber count/fibre core number is set;
(2) power communication distributing cabinet, layout only is equipped with telecommunications breath harvester in its space, both only had the electric power communication device installation site, and realize that the collection of telecommunications system only need to get final product less than the OPLC optical fiber access function of 72 cores, and do not meet the demand of operator's relevant device, and because limited space, section does not have the installation site of operator's relevant device within it, so this kind power communication is not suitable for little high level, high-rise residential quarter Fiber to the home engineering with distributing cabinet.
In order to realize that four nets merge the needs of this new technology, just require to comprise in the fiber box that the device that can either realize the telecommunication service access function comprises again with the telecommunications breath harvester that needs in the power communication.And fiber box does not have ripe product in the prior art, can not take into account simultaneously telecommunication service access and telecommunications breath and gather two functions.
In addition, because in fiber box, be provided with the fusion joining disk that welding optic fibre is used, in the process that realizes optical fiber distributing, realize the welding of optical fiber and tail optical fiber by fusion joining disk, and the volume of fiber box is larger, and fusion joining disk is fixed in the distributing cabinet, just can cause owing to the posetionof weld of being inconvenient to select welding optic fibre the waste of optical fiber.
Summary of the invention
The technical problem to be solved in the present invention is that the equipment that fiber box of the prior art causes owing to space layout is unreasonable taking into account electric power communication device and common carrier unification of three nets is installed needs, and then a kind of fiber box that can take into account simultaneously telecommunication service access and the collection of telecommunications breath is provided.
For solving the problems of the technologies described above, the invention provides a kind of fiber box, comprise casing and cover plate, described cover plate can be fastened on the described casing and form cavity, is provided with fiber adapter in the described casing, and described fiber adapter is 72 core fibre electrical power wiring assemblies; A side of described fiber adapter is provided with optical fiber thermoconnecting tray in described casing, is provided with straight molten plate on the described optical fiber thermoconnecting tray and in described straight molten plate both sides remaining optical cable is coiled the fiber winding disk of storage; Optical cable enters on the inherent described straight molten plate of described casing and the welding of distribution tail optical fiber through incoming line, and described distribution tail optical fiber is connected with the wire jumper tail optical fiber through described fiber adapter, and described wire jumper tail optical fiber is exported described casing through line outlet;
The opposite side of described fiber adapter has been provided with the XPON optical fiber access device of local side OLT, user side ONU equipment and passive optical distribution network ODN integrated in described casing; And optical branching device.
Described optical fiber thermoconnecting tray is removable installed on the base plate of described casing by fixture.
Be provided with the deck of fixing described optical cable on the described optical fiber thermoconnecting tray near a side of described incoming line.
Described fixture is screw bolt and nut.
Described optical branching device is the optical branching device of 1:16.
