If the optical fiber sleeve is improperly fused

If bad welding occurs during the welding of the optical fiber sleeve, possible causes and corresponding solutions are as follows:

First, possible causes of poor welding

Fiber end quality problems:

There are problems of dirt, scratch and uneven bump on the fiber end face, resulting in inaccurate fiber docking during welding.

The cutting Angle of the optical fiber is not appropriate, and the end face is not perpendicular to the optical fiber axis.

Welding machine failure or improper parameter setting:

Welding machine laser failure, electrode aging and other hardware problems.

Welding parameters such as pre-melting time, welding time, cooling time, etc. are improperly set.

Improper operation:

The optical fiber is fed too much or too little, and the driving speed is too fast or too slow.

The optical fiber is affected by air disturbance or unstable operation during welding.

Material issues:

The fiber itself is of poor quality, such as brittleness and easy fracture.

The heat shrink tubing is of poor quality and cannot tightly wrap the optical fiber fusion point after heating.

Second, solutions

Check and clean fiber end faces:

Use an alcohol cotton ball to gently wipe the fiber end face to remove dirt and scratches.

Re-cut the fiber to ensure that the end face is flat, burr free, and perpendicular to the fiber axis.

Adjust welding machine parameters:

Adjust the welding parameters according to the optical fiber type and welding model number.

If the welding machine fails, contact the technician in time for repair or replacement.

Standard operation process:

Keep both hands steady during the welding process to avoid air disturbance of the optical fiber.

Accurately control the amount of fiber feed and push speed to ensure the welding quality.

Replacement of high quality materials:

Use reliable fiber and heat shrink tubing for welding.

Ensure that the optical fiber has a certain mechanical strength and toughness, and is not easy to break.

Discharge experiment:

The discharge test is carried out before welding to make the welding machine adapt to the current environment.

According to the results of discharge experiment, the parameters of welding machine are adjusted to ensure sufficient discharge and good welding effect.

Use AIDS:

In the welding process, auxiliary tools such as wind shield are used to reduce the influence of external factors on the welding quality.

Use tools such as optical fiber clamps to fix the position of optical fibers to ensure welding accuracy and stability.

Reweld:

If the first weld is bad and cannot be repaired, it should be rewelded in time.

Before rewelding, thoroughly clean the optical fiber end face and related parts of the welding machine to ensure that no residual dirt affects the welding quality.

Through the implementation of the above measures can effectively solve the problem of poor welding in the process of fiber sleeve welding, improve the quality and stability of welding and ensure the normal operation of optical fiber communication network.
