The EXFO MaxTester 940 Telco OLTS is a handheld, tablet-inspired Optical Loss Test Set engineered for field certification of fiber optic networks. It measures insertion loss, optical return loss, and fiber length across two wavelengths with automated bidirectional testing completing in under 5 seconds—certifying two fibers at two wavelengths in 2.6 seconds. The device integrates 100% automated fiber inspection with one-step pass/fail analysis, onboard professional PDF reporting, and patent-pending simplex reference technology for reduced test uncertainty on short fiber links.
