Ten reasons for excessive splicing loss of optical fiber

February 23 , 2022
1. Choose the wrong optical fiber splicing program; for example, misselect the single-mode splicing program to multi-mode.
2. The cutting angle of the end face of optical fiber is too large.
3. The optical system is dirty, mainly the reflector and objective lens.
4. V-shaped slot dirty, optical fiber pressure foot dirty.
5. The aging of the electrode leads to the weak discharge intensity, and the excessive discharge of the electrode will also lead to the welding loss.
6. Excessive splicing loss caused by discharge position offset.
7. Horizontal position offset of optical fiber.
8. The change of the technical parameters in the fusion splicer will also lead to excessive welding loss.

9.The addition of dust into CCD will also lead to excessive splicing loss.

10. The inner plate fiber of the fusion plate is not standard, and the installation of the fused fiber pipe is unreasonable.
