Which of the following termination processes typically uses a two-part chemical application?

The termination process that typically uses a two-part chemical application is anaerobic termination. This method involves the use of a specially formulated adhesive comprised of two components: a resin and a hardener. When mixed together, these components undergo a chemical reaction that cures in the absence of air (anaerobic conditions), forming a strong bond that securely terminates the fiber.

The two-part system of the anaerobic process is particularly advantageous for achieving reliable and enduring terminations on various types of fiber optic cables. The structure of the adhesive allows it to fill gaps and form a robust bond between the fiber and the termination setup, ensuring optimal performance and minimal light loss.

Other termination processes such as aromatic, thermal, and mechanical do not involve a two-part chemical application. Aromatic processes generally refer to materials with aromatic hydrocarbon compounds and not specifically to a bonding process. Thermal methods rely on heat to soften or melt materials but do not utilize chemical adhesives in a two-part manner. Mechanical terminations, on the other hand, involve physical means to secure fiber without chemical reactions, using connectors or fixtures to hold the fibers in place. Thus, anaerobic termination stands out with its unique reliance on a two-part chemical system for effective terminations.
