Which termination process does not require any curing?

The cold splice termination process is the correct answer because it involves joining optical fibers without the application of heat or adhesives that require curing. In cold splicing, fibers are aligned and held together using a specialized device that mechanically holds the fibers in a way that allows light to pass from one to the other. This process is advantageous in installations where avoiding heat-sensitive components or the use of adhesives is necessary, as it eliminates the need for any curing time associated with these methods.

Other termination options involve processes that do require additional curing or heating steps. A mechanical splice uses precision alignment to connect the fibers using a mechanical fixture, but it does not require curing. Heat shrink splices involve the application of heat to a thermoplastic sleeve that shrinks around the fibers, which definitely requires a cooling period to secure the splice properly. An adhesive splice uses a bonding agent that also requires time to cure to ensure a proper and secure connection. This further highlights the unique characteristic of cold splice terminations in not needing curing in comparison to the other methods.
