OPGW tangent tower connection, optical fiber leading-out and whole line segment arbitrary point connection method

Abstract

The invention provides an OPGW tangent tower connection, optical fiber leading-out and whole line segment arbitrary point connection method, which comprises the following steps: S1, placing an OPGW on the ground, peeling off the outer layer of the left OPGW, and extending a central tube into a connection box from a left cable inlet of the connection box; S2, orderly penetrating the optical fibers in the tube into the corresponding left fiber core inlet clamping grooves in the box according to the chromatography; S3, enabling the right OPGW to extend a central tube into the box through a right cable inlet of the connection box, and enabling optical fibers in the tube to sequentially penetrate into corresponding right fiber core entering clamping grooves in the box according to the chromatography; S4, enabling the optical cable from which the optical fiber is led out to penetrate into the connection box from the lower cable outlet, and enabling the fiber cores to penetrate into the corresponding lower fiber core outlet clamping grooves; fusing the fiber cores on the left side, the right side and the lower side in the box body according to requirements; S5, stabilizing the leading-out optical cable through a cable inlet fixing pipe at the lower end of the connection box; and S6, placing the connection box at the same position of the tension pay-off sag of the OPGW, and tightly twisting the preformed armor rods on the two sides of the connection box to the OPGW. According to the invention, OPGW tangent tower connection, optical fiber leading-out and connection of any point of the whole line segment can be realized.

Description

technical field [0001] The invention relates to the technical field of optical cable splicing, in particular to an OPGW linear tower splicing method, an optical fiber lead-out, and a splicing method at any point in the entire line section. Background technique [0002] 1. With the rapid development of the national power smart grid and the power Internet of Things, the power communication network plays a key role in the smart grid and the power Internet of Things as a transmission channel and business intelligence, and the optical cable on the high-voltage line is the power communication network. The foundation and important skeleton. Under normal circumstances, the length of the OPGW optical cable is about 5km, and the connection position of OPGW needs to be led down at the tension tower, and then connected by the tower splicing box and fixed on the angle steel of the tower body about 10 meters above the ground with splints. . The straight line tower cannot be used as the ...

Problems solved by technology

[0005] (1) Due to the influence of the terrain, there are often straight-line towers of 2km and above, and the connection of OPGW sub-panels has become an insurmountable hurdle. The conventional practice is that when designing OPGW sub-panels, it is necessary to consider the nearest tension The tower continues, which may cause multi-segment splitting of the line OPGW, and may also cause a single fiber optic cable to be too long or too short, eventually resulting in too many connection points and excessive attenuation in the entire fiber optic cable relay section. Case

[0006] (2) When the tension tower at the connection point of the sub-disc appears on the top of the mountain, if there are straight towers on both sides at this time, the connection point of the optical cable cannot be adjusted

It can only spend a lot of human resources to erect the optical cable reel on the top of the mountain and connect it manually.

[0007] (3) It often happens that the route is changed due to the movement of the occupied land. At this time, OPGW cannot flexibly move with the line. It is necessary to purchase an entire tension-resistant cable reel for the connection on the tension-resistant tower at the head and tail
