Optical cables can be optically polished
Optical fibers can usually not directly be polished, since they are too small and mechanically not sufficiently stable. Therefore, one usually first inserts a fiber into a fiber ferrule consisting of ceramic, glass or metal material. Without a professional polish, connectors suffer from high Insertion Loss (IL) and low. The document is intended to inform and educate about polishing processes and commercial automated polishing equipment with various fixturing in order to achieve a stable low insertion loss, targeted return loss, acceptable 3D endface geometry, and defect free visual fiber. PC polishing creates a gently curved surface, reducing air gaps when connectors are joined.
