Etapas específicas da implementação do projeto

1.Construção externa de cabo óptico

O mais importante para a instalação de cabos ópticos de longa-distância é escolher um caminho adequado de acordo com a estrutura arquitetônica e o ambiente geográfico do edifício. O caminho mais curto não é necessariamente o melhor, mas preste atenção também ao direito de uso do terreno, possibilidade de construção ou sepultamento, etc. Construção razoável de acordo com o projeto de construção e desenhos de construção. Durante a construção, tome cuidado para não colocar o cabo óptico sob forte pressão ou ser perfurado por objetos duros. Quando o cabo óptico gira, seu raio de giro é 20 vezes maior que o diâmetro do próprio cabo óptico.

2.Preparação da construção

Desenvolver planos de organização da construção e medidas de segurança.

（1）Organizational measures:

Set the site leader, technical leader, safety officer and members of the construction team. The safety officer is responsible for the power outage and transmission of the line. The construction team can only enter the site for construction after receiving the notification of the safety officer's work permit.

6. Atravesse as linhas vivas e os obstáculos ao longo da linha com o uso de roldanas de arame suspenso para puxar as roldanas.

3. Technical points in the handling and laying of optical cables

（1） The cable reel should be kept upright during handling and storage. It is strictly forbidden to lay the cable reel flat or stack it, so as to avoid confusion or damage to the cable arrangement.

（2） When rolling the optical cable reel for a short distance, it should be rolled in the direction of the arrow marked on the cable reel, and pay attention to the smooth ground to avoid damage to the protective plate and damage to the optical cable. Fiber optic cables are prohibited from rolling over long distances.

（3） When loading and unloading the optical cable, it is strictly forbidden to roll or throw it directly from the car to avoid damage to the optical cable.

（4）When laying, the tensile force and lateral pressure of the optical cable should be strictly controlled, and the relevant mechanical strength indicators of the optical cable should be inquired if necessary.

（5）The bending radius of the optical cable should be strictly controlled during laying, and the bending radius during construction shall not be less than the allowable dynamic bending radius of the optical cable. The bending radius during positioning shall not be less than the static bending radius allowed by the optical cable.

（6） The twist of the optical cable should be strictly controlled when the optical cable is put through the tube or in sections. If necessary, the inverted "8" method should be used to keep the optical cable in a twist-free state, so as to remove the twisting stress and ensure the service life of the optical cable.

（7）Before connecting the optical cable, a length should be cut to ensure that the connecting part is not damaged mechanically.

（8）The optical cable connection process should be detected by OTDR, and the measurement of connection loss should be calculated by OTDR bidirectional measurement and arithmetic average method.

4. Optical cable termination and termination

（1） The connection of the split welding point of the optical cable adopts permanent optical fiber connection (fusion). This type of connection is to use the method of electric discharge to melt and connect the connection points of the optical fibers together. Its main feature is that the connection attenuation is the lowest among all connection methods, with a typical value of 0.010.03dB/point. However, when connecting, special equipment (fusion machine) and professionals are required to operate, and the connection point also needs to be protected by a special container.

（2） After splicing, the optical fibers should be neatly arranged and reasonably arranged. The optical fiber connectors should be fixed, the remaining length of the optical fiber should be consistent, and the tension should be moderate. There is no twisting and compression phenomenon, and the remaining length of the optical fiber should not be less than 1.2m.

（3） If a heat shrinkable sleeve is used for sealing the optical cable joint sleeve, it should be carried out according to the specified process requirements. After sealing, it should be tested and checked for any problems, and a record should be made for future reference.

（4）The arrangement of optical cable terminal joints or equipment should be reasonable and orderly, the installation location should be safe and stable, and there should be no external facilities such as heat sources and flammable substances nearby that may damage it.

（5）The connector carried by the optical fiber of the tail optical fiber cable or the single-core optical fiber cable drawn from the optical cable terminal joint shall be inserted into the connecting parts on the optical distribution frame according to the design requirements. If the connector is not used temporarily, it can be unplugged, but it should be covered with a plastic cap to ensure that it is not polluted and is convenient for future connection.

（6） In the rack or equipment (such as optical fiber splice box), the optical fiber and the optical fiber joint should be protected, the optical fiber winding direction should be consistent, there should be enough space and the specified curvature radius.

（7）When connecting the optical fiber of the outdoor optical cable, it should be carried out in strict accordance with the operating procedures. The requirements for the concentricity deviation between the fiber core diameter and the center position of the connector joint are as follows:

①The deviation of the concentricity of the multimode fiber should be less than or equal to 3μm;

②The concentricity deviation of the single-mode fiber should be less than or equal to 1 μm.

Se os indicadores especificados não forem atendidos, principalmente quando a perda de emenda da fibra óptica for excedida, ela não deve ser utilizada. O conector deve ser cortado e reconectado, e deve ser usado após passar no teste.

（8） The copper wire, metal shielding layer, metal reinforcing core and metal armoring layer of the optical cable should be connected and grounded according to the design requirements, and it is required to check and test whether they meet the standard requirements. If there is any problem, it must be remedial correction.

（9）Before inserting the optical fiber jumper or optical fiber connector in the optical cable transmission system into the adapter or coupler, use a propanol alcohol cotton swab to wipe the connector plug and the inside of the adapter. It is required to be cleaned before plugging, and the plugging must be tight. , firm and reliable.

（10）There should be eye-catching signs at the connection of the optical fiber terminals, and the content of the signs should be correct, clear and complete (such as the serial number and purpose of the optical fiber, etc.).
