Outdoor fiber laying method

Abstract

The invention discloses an outdoor fiber laying method capable of laying a fiber and improving automation degree, easy to operate, having a low fiber damage rate and a halved workload, and achieving concentrated laying. The method, by pre-installing a linear pulley, a turning pulley, a triple pulley, and a traction machine and by means of constraint of the positions and the distances of the previous modules and the laying sequence of an optical cable, lays the optical cable, achieves high automation degree and high construction efficiency, and reduces fiber loss. In addition, an original fiberterminal box is removed, and all individual optical cables are fusion spliced to a fiber distribution frame to achieve unified incoming, unified fusion splicing, and unified outgoing, and ensure thetidiness, the appearance and the coordination of an equipment cabinet inside an equipment room. The method improves the maintainability of each unit finished cable and the selection diversity of corewires to a certain extent, and achieves good maintainability.

AI Technical Summary

Problems solved by technology

Optical fiber laying technology is a key link in optical fiber communication. In view of the vulnerable nature of optical fiber itself, the degree of automation of construction equipment is low, and there is a lack of guidance documents for construction technology, resulting in increased optical fiber loss and unsatisfactory communication efficiency.
