This provides the quantitative proof of restoration.

The primary purpose of an SOR viewer is to allow engineers and technicians to examine the health of a fiber optic link without needing the physical OTDR equipment present. By loading these files into a viewer, professionals can visualize the "trace" of a fiber—a graphical representation of signal loss over distance—to identify splices, connectors, bends, or breaks in the cable. Key Features of SOR Viewers

An (System Object Repository Viewer) is a utility used primarily in test automation — especially with Micro Focus UFT (Unified Functional Testing) — to inspect and manage object repositories. The SOR (often the shared object repository file with .tsr extension) stores test objects like buttons, text fields, and links that represent UI elements of an application under test.
