What tests are performed on fiber cabling in CRCF?

In a CRCF, routine checks of fiber cabling focus on the physical condition of the connectors. A visual inspection ensures end-face cleanliness, proper mating alignment, and the absence of visible damage or contamination on patch cords and adapters. These factors directly affect insertion loss and reflections, so confirming them visually is the most immediate and non-invasive way to verify fiber integrity in this setting. More thorough tests like optical loss testing or OTDR tracing require dedicated equipment and access to both ends of the fiber, and they’re typically done during initial installation, commissioning, or diagnostic testing outside the CRCF, because they can be disruptive and are not part of routine CRCF upkeep. Tests such as temperature cycling or insulation resistance testing pertain to electrical copper systems and don’t apply to fiber optics, so they aren’t used for fiber cabling in this context.
