Example Embodiment

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

[0012] combined with figure 1 , first insert the two ends of the fiber jumper into the ports to be completed, and guide them to the left at the same time. The fibers of the upper port go up between the cable hook group 6 and the fiber coil column group 7 through the transition disk fiber column 8 to the left line ring group Introduced in 11, the lower end of the optical fiber goes up to the most suitable fiber coil column after the line hook group 6 and the fiber coil column group 7, and then goes down along the gap between the fiber coil column group 7 and the floating line ring group 9, and finally the redundant fiber is installed. It will be accommodated by the floating wire ring group 9 in a suitable slot, and a small amount of residual fiber can be accommodated by adjusting the floating wire ring group 9 . The end of other optical fiber jumpers can be completed simply by repeating the above step...

Example Embodiment

[0013] Example 2, FTTH optical cable connection box access mode

[0014] combined with figure 1 , install and fix the optical splitter 10 in the leftmost channel, and place the input end along the left line to the lower end beam into the trunk port. Insert any ferrule (or a designated one) of the output end into any (or designated) wiring port, and lead the optical fiber to the left along the wiring port to the hook group 6 and the fiber coil column group 7 and go up to the end. The appropriate coiled fiber column is turned backward and descends along the gap between the coiled 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 wire ring group 11, and finally the redundant fiber will be accommodated in the appropriate slot by the floating wire ring group 9, and a small amount of excess fiber can be adjusted by adjusting the floating wire ring group 9 Containment. The remaining outp...

Example Embodiment

[0015] Example 3, the access mode of the terminalless optical cable transfer box (the pigtails spliced ​​with the trunk are directly terminated at the wiring port)

[0016] combined with figure 1 , insert the output port of the trunk into the required end-to-end wiring port, and the optical fiber in the upper position is led to the left to the line hook group 6 and the coil fiber column group 7 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 line hook group 6 and the fiber coil column group 7 to the most suitable fiber coil column and then turns, and goes down along the gap between the fiber coil column group 7 and the floating line ring group 9, and finally the redundant fiber is It will be accommodated by the floating wire ring group 9 in a suitable slot, and a small amount of residual fiber can be accommodated by adjusting the floating wire ring group 9 . The unfinished pigtails ca...

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...
