Fiber optic wiring is a process that requires meticulous operation. Here are some details that need attention:
Select the appropriate type of optical fiber:
Select single-mode optical fiber or multi-mode optical fiber based on the transmission distance and bandwidth requirements. Single-mode optical fibers are suitable for long-distance transmission, while multi-mode optical fibers are more suitable for short-distance and high-bandwidth applications.
Optical fiber end face treatment
Use a dedicated optical fiber peeling pliers to remove the outer skin of the optical fiber, ensuring that the cut is smooth and free of burrs.
Use a fiber optic cutter to cut the end face of the fiber optic, ensuring that the end face is smooth and vertical. Uneven or inclined end faces can cause reflection losses and signal attenuation when optical fibers are spliced.
Optical fiber cleaning
Use a dedicated optical fiber cleaning tool (such as an optical fiber cleaning pen or lint-free paper), dip an appropriate amount of anhydrous alcohol, and gently wipe the end face of the optical fiber to ensure it is clean and dust-free. Any tiny impurity may cause attenuation of optical signals or communication failures.
Selection of continuation method:
According to actual needs, select the appropriate optical fiber splicing method, such as fusion splicing, active connection or mechanical connection. The fusion splicing method has low contact loss, high reflection loss and high reliability, and is a commonly used splicing method.
Welding operation
When using an optical fiber splicer for splicing operations, it is necessary to ensure that the splicer is in good working condition and select an appropriate splicing program.
During the splicing process, it is necessary to maintain the stability of the optical fibers and avoid inaccurate splicing due to reasons such as hand tremors.
After the welding is completed, place the welding point into the welding protection sleeve for physical protection.
Optical fiber bending radius:
During the process of optical fiber splicing, attention should be paid to the bending radius of the optical fiber. The bending radius of the optical fiber should be greater than 20 times the diameter of the optical fiber itself to avoid damage to the optical fiber due to a too small bending radius.
Optical fiber fixation
Fix the spliced optical fibers at the appropriate position with cable ties or clamps to prevent damage to the fibers during movement or pulling.
Optical fiber protection
At the optical fiber connection points and vulnerable parts, heat shrink tubing or mechanical protective sleeves should be used for protection to enhance the mechanical strength and wear resistance of the optical fibers.
Optical fiber testing
Use test equipment such as an optical power meter or OTDR (Optical Time Domain Reflectometer) to check the loss and performance of the optical fiber link and ensure the connection is correct and error-free.
Optical fiber maintenance
Regularly inspect the optical fiber connection points and lines to promptly identify and address potential issues.
Avoid conducting excavation, construction and other activities near optical fiber lines to prevent damage to the optical fibers.
Operating environment
Ensure that the operating environment is clean and dust-free to avoid dust and impurities affecting the cleanliness of the optical fiber end face.
Technical personnel training
Select strictly trained technicians to carry out optical fiber wiring operations to ensure standardized operation and reliable quality.
Document record:
Create detailed wiring documents, including wiring diagrams, test reports and maintenance guidelines, etc., for subsequent reference.
In summary, optical fiber wiring is a process that requires meticulous operation. Attention should be paid to multiple detailed issues such as optical fiber preparation, optical fiber splicing, optical fiber fixation and protection, and optical fiber testing and maintenance. By following the correct operation norms and using appropriate tools and equipment, the quality and stability of optical fiber wiring can be ensured.
