Assembled connector use 1-few day, fiber attenuation becomes larger or fiber broken

Reason:

1. Fiber cut length exceeds 28MM standard

2. Excessive removal of the fiber coating protective layer, lost the protection of the fiber.

3. The fiber bend is too large or the stress is too high, which can easily cause the fiber to be broken.

4. Miller forceps cause fiber damage when peeling off the coating (it cannot be seen with the naked eye). Fiber breaks when shaken by external forces.
