Fiber Optic Communication engineering construction of Fiber Optic Cable line laying technology methods
Fiber Optic Cable routing retest
Before starting the laying of fiber optic cable lines, the entire route must be carefully checked; check the content mainly includes the following aspects.
Firstly, the construction project’s drawing scheme must be strictly inspected, mainly comparing the specific situation at the construction site and whether it is in line with the requirements in the drawings.
Secondly, a scientific and reasonable assessment of the problems encountered during construction must be made in accordance with the construction plan proposed in the construction drawings. The results of this assessment will be an essential construction reference in the specific construction process.
Once again, the actual distance of the route must be measured to provide a real reference for the distribution and laying of the fiber optic cable.
Finally, after the route has been retested, some of the information has to be checked again and again. This part of the information mainly includes the route information marked in the construction drawings, the space reserved for the installation and operation of machinery and equipment information, and geographical information on the location of the cable connection, such as topography, environmental conditions, and so on.
Distribution Plate and Fiber Optic Cable quality inspection
In the construction of fiber optic communication engineering and laying of fiber optic cable lines, one of the key technical points is that the length of the distribution plate and applying section of the fiber optic cable must be controlled scientifically and reasonably. For the effective control of the fiber optic distribution plate, the actual length of the fiber optic cable needs to be scientifically and accurately calculated, as a basis, to ensure the effective control of the fiber optic cable distribution plate.
At the same time, for the effective control of the length of the cable laying section, it is necessary to carry out a scientific and reasonable calculation of its length according to the relevant information in the design drawings to ensure that the calculation results are true and accurate, and then effectively control the size of the laying section, reasonably carry out the laying of optical cable lines to prevent the waste of resources, laying construction does not meet the drawings to note, extend the construction period, increase costs and other issues.
The distribution plate is an indispensable and essential part of the laying of fiber optic cable lines, and its central role is to be able to significantly reduce the number of connections in the fiber optic cable lines to ensure the quality of the cable line design. At the same time, it can also ensure that each part of the optical cable can retain sufficient length for the smooth implementation of the later laying work to do an excellent job of protection.
In addition, the application of the distribution board can also provide convenience for the testing and maintenance of the optical cable line in the later stage, which can make the quality of the optical cable be effectively controlled to ensure that the visual cable line in the actual application, can give full play to its functional role to ensure the regular operation of the optical fiber communication project. Note that these quality control measures must be completed before the laying of the visual cable line.
In addition to these quality control steps, but also the fiber optic cable factory qualification certificate, the appearance of the fiber optic cable for strict inspection, if necessary, the use of optical time domain reflection technology, and the characteristics of the fiber optic cable to test and determine, effectively ensure the quality of the fiber optic cable, to ensure the smooth implementation of fiber optic cable line laying construction land.
Optical Cable line aerial work
In the process of laying fiber-optic cable lines, aerial work is inevitable. In the optical cable line aerial work, the climate is one of the main factors affecting the aerial work.
Therefore, a field survey must be carried out on the climatic situation of the operating position to avoid affecting the smooth implementation of the laying of fiber optic cable lines and also to avoid affecting the quality of signal transmission.
If lightning is more frequent in optical cable line aerial work, lightning prevention and protection measures must be done for the line and optical cable joints when laying operations are carried out.
If the optical cable line aerial work in the region of wind encounters such a climate, must be the length of the visual cable line for scientific and reasonable nurse calculation to ensure that the optical cable line has good tension, effectively reducing the wind on the optical cable line of the adverse impact, to avoid frequent visual cable line by the windbreak.
In addition, in the operation of aerial erection of optical cable lines, should try to choose lighter quality material, and the actual construction must meet the requirements of the design parameters so as to effectively ensure the quality of the aerial operation of the optical cable lines, effectively improve the quality of the aerial laying of optical cable lines and prevent the occurrence of damage to the optical cable lines.
Fiber Optic Fusion Splicing technology
In the construction of fiber optic cable line laying, fiber optic fusion splicing technology is an indispensable and essential part of the quality of fiber optic cable information transmission and has a strong impact.
Therefore, the application of fiber optic fusion splicing technology for the fiber optic cable line laying construction process must ensure that the operation is accurate. Where necessary, fusion splicing of optical fibers is also carried out using instruments with reasonable accuracy.
Application of fiber optic splicing technology needs to pay attention to must guarantee the fusion point around clean, clean, avoid stains or contamination, but also the size of the fusion point range of scientific and reasonable control, which is to ensure the quality of the application of fiber optic splicing technology is a crucial factor, but also to ensure the quality of the laying of optical cable lines vital technical points.
Fiber Optic Cable inspection
First of all, in the optical cable inspection work, one must do an excellent job of checking, which is the critical content of the visual cable inspection. The so-called verification work is the construction site, the purchase of optical fiber cable for quality inspection.
The inspection includes: the quality of the batch of optical cable certificates, construction design requirements, and the actual situation of the cable is consistent, such as model, length, type, and other circumstances. Through the verification work, to ensure that the quality of the optical cable is qualified and in line with the construction design requirements, the quality of the laying of optical cable lines is an excellent job of essential protection.
Secondly, the appearance of the optical cable for testing is also one of the important work content of the visual cable inspection.
In the inspection of the appearance of the cable, they first need to open the cable packaging to check its appearance, whether there are scratches or damage, but also to see the protective cover and cable ends are intact. The cable must be inspected for soft paste hardening at low temperatures if the cable is filled. The temperature should be set between minus 30 and 50 degrees Celsius during the inspection.
During the inspection process, if the fiber optic cable is found to be substandard, the relevant problems must be recorded in detail and reported to the relevant authorities at the first opportunity.
Finally, the performance of the fiber optic cable should be tested comprehensively to ensure that the performance of the fiber optic cable meets the construction requirements of fiber optic communication projects. The most important role of fiber optic cable is to convey information numbers, but in the actual application, it will produce signal attenuation characteristics.
Therefore, to ensure the quality of signal transmission, the signal attenuation performance of the optical fiber cable must be tested in the amount. Detection, the need to use professional testing instruments to effectively ensure that the degree of signal attenuation of fiber optic cable is in line with the relevant provisions of the requirements.
In addition, the insulation performance of the cable is also one of the critical elements of performance testing, and the excellent insulation performance is to ensure that the line in a unique environment and its performance quality can still meet the design requirements of the key. For the inspection of the cable end, it must be well marked, and to ensure that the mark is visible, but also pay attention to the end to do an excellent job of protection measures.
During the inspection process, it is strictly forbidden to use the fiber optic cable in construction if problems are found, and the quality performance does not meet the construction requirements. It must be overhauled until it is confirmed to be qualified before it can be put into use. After the optical fiber cable inspection, it must be repaired and repackaged to restore it to its original state.
Completion acceptance and verification
When the fiber optic communication project is completed, the project needs to be completed acceptance and verification, which is also the last environment of the construction of fiber optic communication engineering.
The completion acceptance and verification work is the last hurdle to ensure the quality of the construction of fiber optic communication engineering and is also a critical warranty link for fiber optic communication engineering. The work of this link is crucial.
In the complete acceptance and verification construction, staff must do an excellent job of dismantling various materials at a later stage of completion of the building, and also after the completion of the application, the inspection department will issue the relevant certificate to effectively ensure the quality safety and operational stability of the fiber optic communication engineering project. Note that it can be formally put into use only when the fiber optic communication project is officially completed and approved.
When the fiber optic communication engineering project is completed, all construction processes and post-completion acceptance and verification procedures must be checked according to national regulations on the management of fiber optic communication project buildings, while all documentation materials valid for construction must also be thoroughly checked to ensure that the construction process is legally compliant.
In the construction of fiber optic communication lines, in addition to regular supervision, random testing of some of the fiber optic cables that have completed construction is also required. Random testing effectively ensures the construction quality of optical fiber communication lines, and the optical fiber cable has a good signal transmission function.
The optical cable line laying completion acceptance and verification stage must be based on the audit results of a comprehensive assessment of the overall construction quality of the foundation to ensure the quality of optical cable line laying construction is in line with the relevant standard requirements, for the construction of visual cable communication project, laying the foundation, do an excellent job of protection.
