Problems solved by technology

This leads to greater waste and intensifies the degree of vicious circle, which has become one of the bottlenecks of fiber access applications
With the wider application of optical fiber access, the previous direct method of trunk and wiring wasted a lot of trunk fiber, and the conventional optical cable transfer box cannot fully meet the application of this technology

Embodiment 1

[0011] Embodiment 1, conventional optical cable transfer box access mode

[0012] combined with figure 1 First, insert the two ends of the fiber jumper into the ports that need to be terminated, and lead them to the left at the same time. The fiber at the upper port goes up between the line hook group 6 and the fiber column group 7 through the transition disc fiber column 8 to the left line ring group. 11, the lower-end optical fiber goes up to the most suitable disk fiber column after the line hook group 6 and the disk fiber column group 7 turn, and goes down along the gap between the disk fiber column group 7 and the floating line ring group 9, and finally the redundant fiber is It will be accommodated in a suitable slot by the floating wire ring group 9, and a small amount of surplus fiber can be accommodated by adjusting the floating wire ring group 9. The termination of other optical jumpers can be completed simply by repeating the above steps.

Embodiment 2

[0013] Embodiment 2, FTTH optical cable transfer box access mode

[0014] combined with figure 1 , install and fix the optical splitter 10 in the leftmost channel, and put the input end along the left line to the lower crossbeam into the trunk port. Insert any ferrule (or a designated core) of the output end into any (or designated) distribution port, and lead the optical fiber to the left along the distribution port to the wire hook group 6 and the disk fiber column group 7 and go up to the most Appropriate disc fiber column turns afterward, and goes down along the gap between the disc fiber column group 7 and the floating wire ring group 9. The optical fiber near the output end of the optical splitter 10 goes down through the ring group 11, and finally the redundant fiber will be accommodated in a suitable slot by the floating ring group 9, and the trace remaining fiber can be adjusted by adjusting the floating ring group 9 containment. The remaining output ports that hav...

Embodiment 3

[0015] Embodiment 3, the access mode of terminalless optical cable transfer box (the pigtail after being fused with the trunk is directly terminated at the distribution port)

[0016] combined with figure 1 , insert the output port of the trunk into the wiring port that needs to be terminated, and the optical fiber at the top is led to the left to the wire hook group 6 and the disk fiber column group 7 and goes up through the transition disk fiber column 8 to the left line ring group 11 Introduced inside, the lower end optical fiber goes up between the wire hook group 6 and the disk fiber column group 7 to the most suitable disk fiber column, then turns, and goes down along the gap between the disk fiber column group 7 and the floating line ring group 9, and finally the redundant fiber is It will be accommodated in a suitable slot by the floating wire ring group 9, and a small amount of surplus fiber can be accommodated by adjusting the floating wire ring group 9. The pigtail...

Abstract

The invention relates to a tow path management system used for an optical cable distribution box in an optical fiber access network, which is characterized in that a wire hook group, a tow coiling column group, a transition tow coiling column, a floating wire loop group, optical branching device groups and left-side wire loop groups are all installed on a wire loop fixed plate; and the left side in the optical cable distribution box is provided with a main tow of an optical branching device, which is connected with an integrative tray of a trunk, an optical cable introduction group is arranged on the wire loop fixed plate, a distance exists among the wire hook group, the tow coiling column group, the floating wire loop group and the left-side wire loop groups, the tow coiling column group is arranged between the wire hook group and the transition tow coiling column, the left-side wire loop groups are arranged above a tow storage box, an integrative tray of a wiring or trunk optical cable is arranged on an integrative tray of a trunk or wiring optical cable, and each optical branching device is correspondingly arranged at the left upper side of each left-side wire loop group. The invention has the advantages that the management of a gradient jumper (tail) tow is carried out by adopting a combined structure, the entire management of the jumper (tail) tow is orderly, a tow path is definite and does not generate an intersection phenomenon, the maintenance is convenient, the utilization rate of the optical cable distribution box is enhanced, and the time is saved.

Description

technical field [0001] The invention relates to a fiber path management system for an optical cable transfer box in an optical fiber access network, and belongs to the technical field of optical transmission terminal equipment and interface equipment of a communication system. Background technique [0002] Due to the management and accommodation of redundant jumper (tail) fibers in the existing optical cable transfer box, the actual utilization rate of the capacity of the optical cable transfer box is less than 50%, which not only causes a huge waste of resources, but also makes the transfer scheduling of the optical fiber in the cable transfer box The functions are greatly limited, and it is very difficult to schedule and search for optical fibers. In this case, operators have no choice but to expand capacity to meet market demand. As a result, greater waste has been aggravated and the vicious cycle has become one of the bottlenecks in the application of optical fiber acce...
