From Fiber Optic Connector Cross Sectioning and Analysis observations from “Connector A” notes

Observations: This particular connector had multiple fractures inside ceramic ferrule (photo A.1-A.3) and a substantial length of fiber missing. See photos A.2 and A.3. From the location of the missing fiber, it appears that the section of fiber came out during assembly prior to thermal curing. This particular fiber received substantial shock during the assembly process (during the fiber insertion).


FOC has seen this before with tight fitting ferrules where fiber was fractured and broken off inside ceramic ferrule while trying to push the fiber thru the hole. Not knowing exactly what hole size this is it appears that the cause of the failure is related to how the fiber was inserted into the ferrule.
