In fiber optics, what characterizes an event that represents a splice?

In fiber optics, a splice is a method of joining two optical fibers together. The characteristic that best represents a splice is low reflectivity. When two fibers are spliced correctly, there is minimal transmission loss at the junction, which means that light can pass through efficiently with very little reflection. High reflectivity at the splice point would indicate poor alignment or improper fusion of the fibers, leading to increased signal loss instead of a clean connection.

Low reflectivity is crucial because it ensures that the splice maintains the integrity of the optical signal as it travels through the joined fibers. Ideally, a well-made splice will have a reflectivity close to zero, allowing maximum light transmission and preserving signal quality.

While high repeatability, strong color changes, and increased loss can all relate to fiber optics, they do not specifically characterize a splice as directly as low reflectivity does, making it the key factor in assessing the quality and efficiency of a splice.
