Poor optical testing of ceramic ferrule
If overpolishing occurs, the only effective way to retrieve the ceramic connector is to cut back the ceramic ferrule surface and repolish the glass. tic connector polishing? Fiber optic connector polishing is a very critical step after connectorization that utilizes an epo y termination technique. Polishing finalizes the connector endface and cleans the surface, which has a direct impact on optical performance parameters such as insertion loss. There are two major uses for visual inspection of fiber optic connectors. There are two types of end faces for the ferrule (either domed or flat) and two types of polishes (either physical contact, PC, or non-conta, NC) addressed. A ferrule's job is to hold the fiber core in perfect concentric alignment while maintaining extremely tight tolerances according to IEC 61755, IEC 61300. 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.
