Measuring insertion loss (IL), optical return loss (ORL) and fiber length calls for an optical loss test set (OLTS). That’s a given, especially for high-count fiber-optic cables considering the greater speed and accuracy of the OLTS over the power meter and light source combo. However, even when using an OLTS the process of re-testing failing fibers can be quite cumbersome.
