Abstract: Recent wide-scale deployment of APC connectors in the outside plant for FTTH initiatives has forced connector manufacturers to consider reliability issues of these connectors. Angled connectors exhibit two phenomena not found in non-angled connectors: First, the lower ferrule endface radius of angled connectors makes the connector more susceptible to permanent fiber withdrawal at elevated temperatures. Second, any rotation of the ferrule in angled connectors will increase the apex offset of the connector. These phenomena may result in loss of physical contact between the fibers of a mated connector pair. This air gap may increase reflectance and insertion loss, reducing system reliability. The air gap may also allow...
