What are the environmental requirements for laying fiber? What is the job of laying optical fibers

There is nothing taboo, the optical fiber is still good, and the anti-interference ability is very strong. The ability to adapt to the external environment is also good. When laying, try to be in a low place that can be artificially damaged, and it is good to protect it with a casing.

The rest can be jacked and go underground. I don't know what the environment my brother is in, but there is no problem with normal natural temperatures. As it was said upstairs, light can't be bent, and it can't be bent.

The turn is definitely arcing.

Optical fiber has strong anti-interference ability, and it is difficult to interfere with electromagnetic waves. As for the high temperature, there will be a protective layer outside, as long as it is not too high, the natural temperature is no problem. I'm not afraid of freezing.

Don't stick to the water. Changes in the volume of water freezing can have an impact. It doesn't matter if you bend it, it's a sure thing that you can't fold.

The turns are definitely arcs rather than corners.

Dear, I'm glad to answer your <>

Answer: The content of the optical fiber laying work: responsible for the field beam laying, splicing and later maintenance of the optical cable.

The main work is the construction of optical fiber engineering, including planning, wiring, splicing, debugging and other work, 1 optical fiber is the abbreviation of optical fiber branch spine Shiwei, the outer layer of the optical fiber Limb protection layer and insulation layer can prevent the surrounding environment from harming the optical fiber. It is a fiber made of glass or plastic that acts as a light conduction tool. 2. The principle of transmission is:'Total reflection of light'。

In everyday life, optical fibers are used for long-distance information transmission because the conduction loss of light in optical fibers is much lower than that of electricity in wires.

Summary. Hello! We're glad to answer your questions!

Hello, there are generally three ways to lay optical fibers: using air blowing installation technology to blow micro optical cables or optical fiber bundles and optical fiber units into pre-laid micro tubes; Make a groove in the cement pavement and place the micro optical cable cloth in the road groove; Fiber optic cables are installed using non-communication pipes.

Hello! I'm glad to answer for you! Hello, there are generally three ways to lay optical fibers: using air blowing installation technology to blow micro optical cables or optical fiber bundles and optical fiber units into pre-laid micro tubes; Make a groove on the rubber surface of the cement road, and place the micro optical cable cloth in the road groove; Install benches such as reed cables with non-communication pipes.

The air blowing method is to use the high-speed airflow of compressed air to blow the micro-cable into the designated pipe. The air blowing laying method has a variety of advantages. Under the high-speed air flow, the micro-cable is in a state of rotten suspension in the pipeline, so the change of topography and the bending of the pipeline have little impact on the optical cable; Subtubes and microcables can be used to improve the fiber assembly density and save pipeline resources. In the early stage, Yu Shou only needs to deploy optical cables of appropriate capacity, and later expand the capacity in stages according to development needs, and blow the optical cables into the sub-tubes of the built mother pipes in batches, which saves the initial investment and avoids a large number of optical fibers being idle; Fiber optic cable branches can be added at any time according to business needs, and Y-shaped connectors are used to reduce the splices of optical cables.

Fiber optic cables for air blowing installation are specially designed for the placement of limb cloths in sub-pipe systems and micro pipes. There are mainly sealed micro optical cables and indoor and outdoor non-metallic dual-purpose micro optical cables. It adopts the structure of optical fiber loose sleeve stainless steel tube, which not only has the general characteristics of small outer diameter and light weight of micro optical cable, but also has excellent high and low temperature xing energy and side pressure resistance.

The stainless steel pipe is made of laser welding stainless steel strip, which seals the optical fiber and fiber paste inside, and the accurate residual length control technology can ensure the use of optical cable in complex environments. Moreover, the stainless steel pipe has excellent moisture-proof energy and physical anti-rodent, anti-ant energy and anti-acid energy, which can give good protection to the optical fiber and minimize the damage of the optical cable.

1) The construction of optical cable should be carried out in strict accordance with the construction specifications;

2) When the optical cable turns, its turning radius should be greater than 15-20 times the diameter of the optical cable itself, such as the overhead optical cable in the upper and lower towers, the bending angle should be reduced as much as possible, and at the same time the optical cable tray should be assisted to reduce the tension of the optical cable's defense line;

3) Before the deployment of the optical cable, the construction and related personnel should be properly trained on the matters that should be paid attention to in the construction, such as the essentials of pay-off methods and safety, and ensure that the construction personnel obey the command;

4) Relevant personnel should be arranged to be distributed at the pay-off of the optical cable reel, crossing the obstacle point, the terrain bend, etc., so as to find the problem in time, eliminate the fault, control the speed in the pay-off, and reduce the tension of the pay-off reel;

5) If there is an obstacle in the process of fiber optic cable deployment, stop dragging and dropping and eliminate it in time. It cannot be dragged through with great force, otherwise it will cause damage to the optical cable;

6) When the optical cable is pay-off, the tension should be stable and should not exceed the required tensile force of the optical cable standard.

7) When the optical cable is subjected to large tension and passes through a pulley with a small bending radius or a hard surface with edges and corners at a small angle, the local side pressure of the optical cable will be much greater than the rated value, so that the internal structure of the optical cable will be damaged, and in serious cases, the fiber will be broken.

8) The construction unit of the optical cable should constantly sum up experience, strive to improve the construction quality, and prevent the occurrence of similar construction accidents.
