End-face Check- Verifies that both side fibers are cleaved to the tolerance required by that splicer. Arc Check- Tests the current conditions (hardware and environmental) to warn if arc current needs to be adjusted. Altitude Compensation- Automatically adjusts the arc current for the. This guide reveals the secrets to fusion splicing with little fluff—just proven, straightforward techniques refined from years of work in the field. The guide provides the complete workflow, covering safety precautions, tool selection, fiber preparation, fusion operation, quality control, and. Corning Cable Systems OptiSplice® M90e Fusion Splicer is the next generation of the proven M90 Fusion Splicer and is the ideal machine for networks where low-loss performance and high-end accuracy are imper-ative. Fusion splicing is the most widely used method of splicing as it provides for the lowest loss and least reflectance, as well as providing the strongest and most reliable joint between two fibers. Fusion splicing is the bedrock of high-performance fiber optic networks, enabling seamless signal transmission through permanent, low-loss fiber joins. When more than one fibers are. In contrast, an optical time-domain reflectometer (OTDR), is preferred for such field splicing situations since they can effi-ciently characterize fusion splices during field installation, even from a remote location many kilometers from the fusion splice. In a factory or production environment.
