What are the problems involved in the deployment of pipes and optical cables?

Summary. The network speed is basically more than 10m. The higher the fee, the greater the fee.

The fiber is very small, but the toughness is great, and it will not break when wound into a ring with a diameter of only 2 mm; An optical fiber that is only as thick as a hair can lift a weight of 7 kilograms, and optical fiber communication has large capacity, low transmission loss, no electromagnetic interference, small size and light weight. A single optical fiber can turn sound, text, images, etc. into optical signals, which can be transmitted at a speed of 3 billion kilometers per second.

What are the benefits of fiber optic cable conduits, and on what basis.

The network speed is basically more than 10m. The higher the fee, the greater the fee. The optical fiber is very small, but the toughness is great, and it will not break when wound into a circular reed ridge with a diameter of only 2 mm; An optical fiber that is only as thick as a hair can lift a weight of 7 kilograms, and optical fiber communication has large capacity, low transmission loss, no electromagnetic interference, small size and light weight.

The amount of optical fiber communication is not large, and a wild optical fiber can turn sound, text, images, etc. into optical signals, which are transmitted at a speed of 3 billion kilometers per second.

That's his benefit.

Optical fiber cable (optical fiber cable) is mainly composed of optical fiber (thin glass filament as thin as hair) and plastic protective sleeve rental training tube and plastic sheath, there is no gold, silver, copper and aluminum and other metals in the optical cable, and generally has no value. Optical cable is a kind of communication line that is composed of a certain number of optical fibers in a certain way, covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission.

Justification for catheters.

This is also one of his bases.

We added PE pipes when we installed them, please find a reason and advantages.

Heat resisting. It is not easy to damage.

Answer]: B This question examines the handcode of communication facilities. When the optical cable is worn and placed in various types of pipes, the inner diameter of the pipe should not be less than the outer diameter of the optical cable.

Answer] :d 2022 edition textbook p298

2) When laying pipes such as virtual light and cables, Brother Shanxu uses liquid paraffin, talcum powder, etc. as lubricants, and it is strictly forbidden to burn slag dust with organic grease

1. The following preparations should be made before the laying of pipeline optical cables:

1) Check the position of the pipe hole occupied by the optical cable according to the design;

2) The hole position selected on the same route should not be changed, such as change or turning, it should meet the requirements of the bending radius of the optical cable;

3) The pipe holes used must be cleaned.

2. When manually laying optical cables, each hole should be manned; When the optical cable is laid out mechanically, the manhole should be manned.

3. When the optical cable penetrates the pipe hole or the pipeline bends or crosses, the guide device or bell mouth protection pipe shall be used to protect the pipe, and the outer sheath of the optical cable shall not be damaged. A neutral lubricating ligator can be applied around the cable as needed.

4. The length of a towing cable is generally not more than 1000 meters. When it is too long, it should take 8-figure segmented traction or intermediate auxiliary traction.

5. After the optical cable is deployed, the optical cable should be placed on the specified supporting plate one by one under the unified command of a special person, and an appropriate margin should be left to avoid the optical cable being stretched too tightly.

6. The reserved length of the optical cable in the manhole where the joint is located shall comply with the provisions in the table; The design requires that the fiber optic cable be specially reserved and stretched too tightly.
