Dimension Technology's self-developed multi-core OTDR can test multiple fibers at the same time, saving a lot of testing time. OTDR testing analyzes fiber optic cable performance from end to end by testing components along the cable, including connection points, bends, and splices. What Is an OTDR? What Is an OTDR? An OTDR is a powerful tool that helps technicians and engineers assess the health of fiber optic cables. For fiber characterization, the testing equipment will need to measure/find the following key parameters: Insertion loss (IL): The loss of signal power expressed in decibels (dB) that results from the presence of an event on a fiber link, such as a splice or a connector. The product adopts the architecture of test module + handheld universal test platform, integrating OTDR, visual fault. VIAVI provides the widest range of OTDR testing tools delivering everything from basic fiber certification to fully automated bidirectional OTDR testing that scales for multi-fiber cable certification. I've spent months researching. SmartLoop™ OTDR technology tests two fibers in a single test eliminating the need to travel to the far end of the connection to perform tests. Integrates with LinkWare™ Live to manage jobs and testers from any smart device. Future-ready VersivTM design supports copper certification to Category 8.
