Which of the following best describes Fusion Splicing?

Fusion splicing is best described as a method to reduce loss in optical links. This technique involves joining two optical fibers end-to-end using an electrical arc or heat source to fuse the glass fibers together. By achieving a seamless connection, fusion splicing minimizes the amount of light that is lost at the junction between the two fibers, significantly improving the overall performance of optical communication systems.

In contrast, while preparing fibers is a necessary step prior to fusion splicing, it does not capture the essence of what fusion splicing accomplishes. Measuring decibels pertains to assessing signal strength or loss but does not directly describe fusion splicing itself. Additionally, while fusion splicing is related to optical fiber installation, it is not a physical component of the cables, rather the process that connects them effectively.
