TAILIEUCHUNG - Endface Geometry and Connector Reliability in the Outside Plant

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. | PON Deployment of Angle Polished Connectors Endface Geometry and Connector Reliability in the Outside Plant PON Deployment of Angle Polished Connectors Endface Geometry and Connector Reliability in the Outside Plant By Steven C. Zimmel 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 contaminants to migrate on the fibers. Ferrule rotation and permanent fiber withdrawal need to be minimized for acceptable connector performance in the outside plant. 2005 Optical Society of America OCIS codes Fiber optic components Introduction Angled physical contact APC fiber optic connectors with zirconia ferrules have become the de facto standard in PON networks currently being deployed for FTTH initiatives. The angle on the fiber in APC connectors produces low back reflections when the connector is not mated to another connector Reflected light is directed into the fiber cladding because the endface angle is greater than the acceptance angle of the fiber. The low reflection of an unmated APC connector provides an advantage for PON networks A connector in the PON will usually remain unmated until service is required from that circuit. This results in unused connectors emitting their signal into air which can produce Frensel reflections as high as -14dB for connectors without an angle on the endface. .
