What technique is used for preparing optical fibers for termination?

The technique used for preparing optical fibers for termination is score and cleave. This method involves scoring the fiber at a precise location and then applying a clean break to create a smooth end face. This smooth surface is crucial for effective light transmission when the fiber is connected to other optical components or systems.

Achieving a proper cleave is essential because any imperfections on the fiber end face can result in increased signal loss, reduced performance, and potential core misalignment when fibers are joined. The scoring process is usually done with a specialized tool that ensures the score line is consistent and accurate, followed by a cleaving process that results in a flat and perpendicular fiber end.

Other options do not pertain to the fiber termination readiness. Patch cords refer to pre-terminated fiber cables used for connections but do not explain the preparation method. Chromatic dispersion is a phenomenon that affects signal quality over long distances in optical fibers, rather than a preparation method. Electromagnetic waves, while relevant to the functioning of optical fibers, do not relate to the termination technique itself.
