A(n) _____ splice uses ferrules that are rotated when the splice is being made.

A splice that uses ferrules which are rotated during the splicing process is referred to as a polished-ferrule splice. This method is commonly employed in optical fiber splicing to achieve a precise alignment of the fiber cores. The rotation of the ferrules allows for optimal contact between the two optical fibers, minimizing splice loss and ensuring a strong connection, which is crucial for maintaining signal integrity in fiber optics.

Polished-ferrule splicing typically involves the use of polished surfaces that enhance the quality of the optical connection. This technique is particularly advantageous in scenarios where low-loss splices are required, such as in high-speed communication networks. The careful alignment and the rotational action help in compensating for minor misalignments and imperfections in the fiber ends, resulting in improved performance.

Understanding the mechanics of a polished-ferrule splice is essential for technicians and engineers working in the field, as it highlights the importance of precision in fiber optic connections and the role of ferrule design in achieving effective splicing results.
