In fiber optic terminations, what process involves inserting prepared fiber into a connector before cleaving?

The process that involves inserting prepared fiber into a connector before cleaving is known as "Scribe and Polish." This method entails preparing the fiber end face by polishing it to achieve the necessary level of optical quality before it is terminated with a connector. The scribing is a technique that helps to create a flat and smooth surface at the end of the fiber, which is crucial for ensuring low insertion loss when the fiber is mated with other optical components.

When using this method, the fiber is inserted into the connector first, creating a temporary connection. After the fiber is secured in position, it can be cleaved to achieve the desired length and to ensure the end face is properly aligned for optimal performance. This process facilitates a precise and effective termination, enabling better signal transmission through the fiber.

The other options provided do not properly describe the specific sequence of inserting fiber before cleaving. "Cleave and Secure Connectors" refers more to the process of cleaving the fiber followed by securing it with a connector, but does not specify the insertion step prior to cleaving. "Pigtail Splice" typically involves fusion splicing a short length of fiber to another fiber or to a cable, which does not pertain to the specified process. "Heat
