Fiber Optic Testing is a process used to ensure the performance and reliability of fiber optic cables. This testing checks for issues like signal loss, reflection, and overall transmission quality. It helps identify problems that could affect data transfer in communication networks. Various methods are employed in fiber optic testing, including OTDR (Optical Time Domain Reflectometer) and power meter tests. These techniques measure the light signals traveling through the cables, allowing technicians to pinpoint faults and verify that the installation meets industry standards. Regular testing is essential for maintaining optimal network performance.
