Which fiber connector uses a ceramic ferrule to align the core and prevent light ray deflection?

• A. SC Connector
• B. LC Connector
• C. MT-RJ Connector
• D. ST Connector

Answer: (A)

Precise core alignment is what a ferrule provides in a fiber connector. The ferrule holds the stripped fiber in a very exact bore so the fiber tip sits squarely along the connector axis and is perpendicular to the mating surface. A ceramic ferrule is favored because it’s rigid, dimensionally stable, and manufactured with a very smooth bore, which keeps the core centered and the end face flat. When the core is properly aligned like this, light travels straight into the mating fiber with minimal deflection, reducing insertion loss and back-reflection.

In the common connector style described, this approach is implemented with a ceramic ferrule to position the fiber accurately, making it the best choice for a connector that uses a ceramic ferrule to align the core and prevent light-ray deflection.
