Description

Disconnect-type optic fibre stores up fine box

Technical Field

The invention relates to the technical field of communication operation, in particular to a separated optical fiber storage box.

Background

With the development of communication technology, optical fiber communication technology has become the mainstream. The optical transmission network is composed of communication nodes and communication light paths. The communication node is an optical transmission device mainly comprising an SDH device, and the communication optical path is a communication optical cable. The length of the communication optical cable is limited, and when the distance between the communication nodes is larger than the length of the communication optical cable, the two optical cables are connected in a jumper connection mode in engineering to provide a required optical path. The optical transmission device is also accessed to the optical path in a jumper connection mode. The operation of a jumper requires a fiber jumper as a physical connection. Because the lengths of the optical fiber jumpers are different, in order to meet the process requirements, redundant jumpers are often wound in the fiber storage box. However, when the optical path quits the operation, the jumper quitting operation is extremely complicated due to the design structure of the fiber storage box, the labor time is wasted, the working efficiency of communication operation detection is greatly reduced, and a new fiber storage box is urgently needed to solve the problem that the jumper quitting is complicated.

The problems existing in the prior art are as follows: currently, fiber storage boxes are designed to receive redundant optical fibers. As the length of redundancy increases, three problems tend to arise: firstly, when the optical path exits, a large amount of time is consumed for exiting operation due to winding stress of the corresponding physical optical fiber; secondly, in the process of exiting the physical optical fiber, the running optical path is easily dragged to cause optical path interruption alarm, so that serious consequences are caused to a communication network; thirdly, when a large amount of redundant physical optical fibers appear in the optical fiber storage box, an operator considers that exiting operation easily causes interruption of an operating optical path and alarm, so that worry about dislike emotion is easily generated, and finally abandoning the exiting operation on the physical optical fibers causes more physical optical fibers of the optical fiber storage box, so that daily operation, maintenance and repair work of a communication line is seriously influenced. Moreover, current fiber storage cassettes lack programming-aid functionality, resulting in a mess of twisted redundant fibers.
