Fusion splicing is used to physically join together two optical fiber ends. The process may vary, depending on the type of fusion splicer used. FITEL splicers are simple yet precise and reliable tools that can support a full range of fiber manufacturing, R&D, installation, and maintenance applications. Fusion splicing permanently joins two optical fibers when no additional changes to those fibers are expected at that juncture. This is in contrast to connectors, which are designed to allow quick re-configuration of fiber links.
