Description
Technical field
What the utility model cable formula optical branching device related to is a kind of cable formula optical branching device that is applied to occasions such as Optical Distribution Frame, light distribution cabinet, particularly 1 * 32 reaches following cable formula optical fiber splitter.
Background technology
Along with people improve constantly the demand of bandwidth and speed, fiber-to-the-home construction has just in time solved the demand that people increase day by day, in Fiber to the home network, be in core status device--the application of optical branching device also welcomes spring.
Traditional shunt has several structural shapes: boxlike shunt, rack shunt, and the shunt that it is fine to have solved light signal during Fiber to the home, but in actual applications, there are several point defects in traditional shunt: the one, and it is bigger to take up room; The 2nd, wiring bothers in originally with regard to little frame or distribution cabinet.
Summary of the invention
The purpose of this utility model is to provide a kind of cable formula optical branching device at above-mentioned weak point, adopts thimble assembly, heat-shrink tube, the naked module making of optical branching device to form.Compare with traditional optical branching device, have structure little, occupy little space, bending radius is little, be easy to wiring and advantages such as installation.
Cable formula optical branching device takes following scheme to realize: cable formula optical branching device has the naked module of optical branching device, pyrocondensation protection tube, sleeve pipe, sheath and connector; the naked module of optical branching device has input end fiber, branch's chip and output terminal optical fiber; the naked module of optical branching device is provided with sleeve pipe outward; adopt the protection of pyrocondensation protection tube at the two ends that the naked module of sleeve pipe and optical branching device is connected; sheath is arranged on the naked module of the optical branching device that is provided with sleeve pipe outside; the coupling part at its two ends adopts the pyrocondensation protection tube to connect, and connector is arranged on the said modules two ends.
Described sleeve pipe is the sleeve pipe of 0.9mm.The naked module of described optical branching device can adopt the commercially available naked module of PLC planar waveguide-type optical branching device.Described sheath is the pencil cable jacket.
Described input end fiber is one.Described output terminal optical fiber is 8～32.
When the utility model cable formula optical branching device is made; encase the two ends of the naked module of optical branching device earlier with the pyrocondensation protection tube; behind the fiber optic protection with two ends; be through in the sleeve pipe; reusable heat cripetura protection tube is put on fiber optic protection behind the sleeve pipe with two ends; with the assembly that processes, integral body is through among the sheath then.
Cable formula optical branching device in use, notion by the pencil wire jumper, make that planning and construction are more prone in the building, can draw 1 core master fibre from the trunk branch point, dock this shunt, directly be put in the interior a plurality of users residence of floor with this cable formula optical branching device cloth, not needing is that shunt is installed special etui again; Length before and after the difference can be carried out customized according to customer requirements; Can also be in light be handed over installation do not take and moltenly join the unitary space, can make same Capacity Optical friendship obtain more link support space.Save the occupation of land space widely, reduced wiring difficulty and complexity.
Description of drawings
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the naked module diagram of shunt of the present utility model.
Fig. 2 is of the present utility model 1 * 32 and following cable formula optical branching device synoptic diagram.
Embodiment
With reference to accompanying drawing 1～2; cable formula optical branching device has the naked module of optical branching device, pyrocondensation protection tube 4, sleeve pipe 5, sheath 6 and connector 7; the naked module of optical branching device has input end fiber 1, splitter chip 2 and output terminal optical fiber 3; the naked module of optical branching device is provided with sleeve pipe 5 outward; adopt 4 protections of pyrocondensation protection tube at the two ends that the naked module of sleeve pipe 5 and optical branching device is connected; sheath 6 is arranged on the naked module of optical branching device outside; the coupling part at its two ends adopts pyrocondensation protection tube 4 to connect, and connector 7 is arranged on the said modules two ends.
When cable formula optical branching device is made; earlier the input end fiber 1 of the naked module of optical branching device and output terminal optical fiber 3 are through among the sleeve pipe 5; two ends are protected after adopting 4 pyrocondensations of pyrocondensation protection tube; the effect that is connected and fixed of the naked module of optical branching device and input end fiber 1 and output terminal optical fiber 3 is strengthened in the blended rubber hydropexis.Then the assembly that processes is through among the pencil cable jacket 6, the coupling part at two ends connects with pyrocondensation protection tube 4, handles the two ends, back well and processes the connector 7 of required type.
Described sleeve pipe is the sleeve pipe of 0.9mm.The naked module of described optical branching device can adopt the commercially available naked module of PLC planar waveguide-type optical branching device.Described sheath is the pencil cable jacket.
Described input end fiber 1 is 1.Described output terminal optical fiber 3 is 8～32.
