Reliability of glass-ceramic ferrules in the severest conditions

In this paper, specially assembled connectors concatenated were tested under long term reliability tests by polishing ferrules endface as just exceeding the border value of the above proposed parameters. The proposed dimensions were experimentally verified. Water immersion tests done for both GCF-using connectors and ZrF-using connectors showed that GCF is highly reliable in the severest outside conditions like FTTH.
