Abstract: In some examples, dual-end loopback-based multi-fiber cable measurement may include connecting at least two multi-fiber loopback devices respectively to a near end and a far end of a multi-fiber cable to place at least two fibers of the multi-fiber cable in series. The at least two multi-fiber loopback devices may include a near-end multi-fiber loopback device connected to a fiber optic reflectometer and to the near end of the multi-fiber cable to connect together at least two near-end fibers of the multi-fiber cable. Further, the at least two multi-fiber loopback devices may include a far-end multi-fiber loopback device connected to the far end of the multi-fiber cable to connect together at least two far-end fibers of the multi-fiber cable.
