Action Taken Code H relates directly to which kind of procedure?

The correct choice pertains to "Repair using termini." Action Taken Code H is specifically designated for repairs involving termini in fiber optic systems. Termini refer to the end connectors of fiber optic cables, where the optical fibers are attached for signal transfer. This code indicates that during maintenance or repair tasks, the work carried out directly relates to the installation, testing, or replacement of these connectors to ensure proper functionality and performance of the fiber optic network.

Understanding this context is crucial in recognizing that while other options involve aspects of fiber optic repair, they do not accurately reflect the specific procedure denoted by Action Taken Code H. For example, repair of fiber optic segments focuses more on the fiber itself rather than the connections at the ends. Similarly, alteration of maintenance documentation and repair using splicing has distinct connotations that do not align directly with the function and significance of using termini in fiber optic applications.
