All fiber patch cable connectors have a ferrule end face where the fiber strand is centered to allow it to mate with another fiber assembly or attach directly to a piece of equipment. If you look at the connector, the ferrule end face is the exposed white ceramic tip of the fiber. The detection and cleaning of connector end faces is a very important task in the field of optical communication, as contamination of device end faces can cause attenuation of optical signals and affect communication quality. Therefore, the detection and cleaning of the end faces of optical active. This document outlines the Panduit recommended procedures for visual inspection and cleaning of multimode and singlemode structured cabling system interconnect components (connectors and adapters) and specifies workmanship requirements, tools and best practices, to be utilized for end face. The end-face geometry of these connectors plays a critical role in minimizing optical losses and ensuring long-term mechanical reliability. Standards such as IEC 61300-3-47, Basic test and measurement procedures for end face geometry of PC/APC spherically polished ferrules using interferometry, and. A piece of dirt, speck of dust or any foreign particle/contaminant in the critical position of the optical end face connector may cause high reflection, insertion loss and fiber optical end-face damage. Traditional end face inspections are usually performed by manual visual methods, which are.
