What if the fiber sleeve cracks after heating

If the fiber sleeve cracks after heating, this may be due to high heating temperature, improper heating time or improper selection of fiber sleeve material caused by reasons such as. To address this problem, the following measures can be taken:

First, emergency treatment

Stop heating: immediately stop heating the fiber sleeve to prevent further crack expansion.

Isolate the damaged area: Use warning labels to isolate the damaged fiber sleeve area to prevent damage to other devices or optical fibers during handling.

Second, cause investigation

Check the heating device: Check whether the temperature setting of the heating device is too high, or whether the heating time exceeds the limit that the optical fiber sleeve can withstand.

Review the casing material: Check whether the material of the fiber sleeve is suitable for the current heating process, and the heat resistance of different materials of the fiber sleeve is different.

Review the operation process: Review the entire heating process to confirm whether there is improper operation or negligence, such as uneven heating, casing fixing.

Third, repair or replace

Repair cracks:

For smaller cracks, you can try to use a special sealant or adhesive to repair, but it should be noted that the performance of the repaired casing may be affected.

Before repair, the area around the crack should be thoroughly cleaned to ensure that there is no dust, grease and other pollutants.

Sleeve replacement:

If the crack is large or the repair effect is not ideal, it is recommended to replace the optical fiber sleeve directly.

During the replacement process, ensure that the new casing is of reliable quality and compatible with the current optical fiber and heating equipment.

Fourth, preventive measures

Correct selection of optical fiber bushing: When purchasing optical fiber bushing, you should carefully read the product manual, understand its heat resistance, material and other key parameters, and select the appropriate bushing according to the actual needs.

Reasonable use of heating equipment: When using heating equipment, it should be strictly operated in accordance with the requirements of the product manual to ensure that the heating temperature and heating time are within the range that the casing can withstand.

Strengthen construction supervision: In the installation and heating process of optical fiber sleeve, construction supervision should be strengthened to ensure that each step of the operation meets the requirements of the code to avoid cracks caused by improper construction.

Fifth, follow-up inspection and testing

Appearance check: After repairing or replacing the casing, check the appearance of the optical fiber casing to ensure that there are no cracks or deformation.

Performance test: Use professional equipment such as optical fiber tester to test the repaired or replaced optical fiber to ensure that the signal transmission quality meets the requirements.

Through the implementation of the above measures, can effectively solve the problem of crack after heating fiber sleeve, and prevent similar problems from happening again.
