What process involves joining two fiber ends by melting them together?

The process of joining two fiber ends by melting them together is known as fusing. Fusing involves applying heat to the ends of the optical fibers, causing the glass to melt and flow together, effectively creating a continuous optical pathway. This method is essential in fiber optic communications as it minimizes signal loss and optimizes performance by creating a strong, seamless connection.

Other terms, while related to the general concept of linking fibers, do not specifically describe the melting process. Splicing refers to various methods of joining fibers together, which may include fusion but also encompasses mechanical splicing and other techniques. Joining is a more generic term that could imply different forms of connection, and connecting typically refers to a broader spectrum of linking devices or systems rather than the specific melting process inherent in fusing.
