Precautions for installing optical fiber tubes

When installing an optical fiber sleeve, pay attention to the following key items to ensure the stability of the optical fiber connection point and signal transmission quality:

First, fiber preprocessing and splicing

Optical fiber cleaning: Before connecting the optical fiber, use alcohol cotton or other special detergent to thoroughly clean the surface of the optical fiber to remove impurities such as grease and dust to prevent pollution from affecting the connection quality.

Precise cutting: Use a professional optical fiber cutting knife to cut to ensure that the optical fiber end face is flat and without burrs, and the cutting Angle meets the standard to ensure the optical transmission efficiency of the connection point.

Welding quality: In the welding process, pay close attention to the display screen of the welding machine to ensure that the welding quality meets the requirements and avoid bubbles, virtual melting and other phenomena.

Second, casing selection and installation

Casing matching: Select the appropriate casing based on the type, diameter, and connection method of the fiber. Casing should have good mechanical strength, corrosion resistance and thermal stability to ensure long-term reliability.

Insert the fiber into the casing: Gently insert the fused fiber into the casing to avoid excessive stress or bending of the fiber. Ensure that the optical fiber is tightly fitted to the inner wall of the casing to avoid voids or air bubbles.

Fixed casing: For casing that needs to be fixed by heating (such as heat shrink casing), heat it evenly using a heat gun or other heating tool. When heating, strictly control the temperature and time to avoid burning the casing or damaging the optical fiber. After the heating is complete, the casing should be tightly wrapped around the fiber connection point to form an effective protective barrier.

Third, installation environment and safety

Environmental control: During the installation process, pay attention to controlling the temperature, humidity and cleanliness of the surrounding environment. Avoid installation in wet, dusty or extreme temperature conditions to prevent adverse effects on the fiber and bushing.

Safety protection: When heating the casing and other operations, to take safety precautions, such as wearing protective glasses and gloves. Avoid burns or other accidents.

Fourth, follow-up inspection and testing

Appearance check: After the installation is complete, carefully check whether the sleeve is fixed and the bending radius of the optical fiber meets requirements. Ensure that the casing completely covers the optical fiber connection point and the surface is smooth and intact.

Performance test: Use optical time domain reflectometer (OTDR) and other test equipment to test the fiber connection point to ensure that the connection quality meets the requirements and the signal transmission is stable. Through testing, potential problems can be found and repaired, and the reliability of optical fiber communication system can be improved.

To sum up, attention should be paid to fiber preprocessing and splicing, casing selection and installation, installation environment and safety, and subsequent inspection and testing during the installation of the fiber sleeve. Only by strictly operating in accordance with the specifications and paying attention to related matters can the stability of the fiber connection point and the quality of signal transmission be ensured.
