What is a fusion splicer used for?

A fusion splicer is specifically designed for joining two fiber optic cables together using heat. This process involves aligning the ends of the fibers with great precision and then applying an electric arc that melts the fiber ends, fusing them into a single continuous strand. The result is a strong, low-loss connection that is crucial for maintaining the integrity of the optical signal.

The method used by fusion splicers is advantageous because it typically produces joints that have lower signal loss compared to mechanical splicing methods, where fibers are aligned but not fused, possibly resulting in higher attenuation. This technology is essential in fiber optic networks where performance and reliability are paramount.

In contrast, other options refer to different aspects of fiber optic maintenance and installation. Cleaning fiber optic cables, measuring light power, and terminating connectors are all vital tasks, but they serve different purposes within the overall fiber installation and maintenance process.
