What is meant by the connector end face type and finish?
The IL and RL measurements can be improved by altering the contact surface between the fibres and connector. Surfaces can be cut at different angles, and polished to different levels. The different types of finish available are detailed below. PC (Physical Contact) – Most generally used end face finish for all connector types. The connector is supplied with a polished radiuses convex face to give Physical contact at the fibre core interface. Insertion Loss <= 0.4db Return Loss >= 30db SPC (Super Polished Physical Contact) – End face shape is the same as the standard PC connector but and additional fine polish is applied to the face of the connector to improve both insertion and return loss. Insertion Loss <= 0.3db Return Loss >= 45db UPC (Ultra Polished Physical Contact) – End face shape is the same as the standard PC connector but and an extra fine polish is applied to the face of the connector to improve both insertion and return loss.
