Optical cable construction process and problem analysis

The construction process and problem analysis of the optical cable are as follows. The optical cable is a communication line in which a certain number of optical fibers form the core according to a certain method, and the outer sheath is covered, and some are also covered with the outer sheath to realize optical signal transmission. That is: an optical cable formed by an optical fiber (optical transmission carrier) through a certain process. The basic structure of an optical cable is generally composed of a cable core, a reinforced steel wire, a filler, and a sheath. In addition, there are waterproof layers, buffer layers, and insulating wires as needed.

What are the construction procedures for optical cables?

The construction procedures of general optical cable lines are mainly divided into five stages: preparation, laying, connection, testing and completion acceptance.

①Optical cable single-disc inspection: check the appearance of the optical cable, the relevant characteristics of the optical fiber and the signal line, etc.

② Line retest: According to the construction design drawing, review the specific direction of the line, laying conditions, environmental conditions, and the specific position of the joints, ground distance, distribution board, distribution, etc.

③ Optical cable wiring: Calculate the total laying length according to the retest route, and choose the length of the optical cable reel reasonably.

④ Line preparation: pipeline cleaning, pre-laying of iron wire or plastic conduits before laying optical cables, pre-laying of steel wire ropes and hooks before overhead laying, excavation of optical cable trenches before direct burial laying, setting of joint pits, etc. It is conducive to the smooth progress of the project and the installation of optical cables safe laying.

⑤ Optical cable laying: According to the laying method, hang the single-disk optical cable rack on the pole or pull it into the pipe, or put it into the optical cable trench.

⑥ Fiber optic cable connection installation: including fiber optic connection, copper wire, aluminum sheath, strengthening core connection, and joint loss measurement. Encapsulation of joint sleeves and support of joint protection, etc.

⑦Relay measurement: including optical fiber characteristics (such as optical fiber total attenuation, etc.) testing and copper wire electrical performance testing, etc.

⑧ Optical cable completion acceptance: provide construction drawings, modify routing diagrams and measurement data and other technical information, do a good job of on-site inspection and completion acceptance, provide qualified optical fiber lines, and ensure that the system is put into operation.

The above is about what is an optical cable and what are the construction procedures of the optical cable. I believe you have seen some answers about what an optical cable is and the structure of an optical cable.
