This is a handheld Optical Loss Test Set (OLTS) that integrates triple-wavelength laser sources at 1310, 1550, and 1625 nm with an InGaAs detector and APC connectors. Featuring the built-in VisiTester option, it enables quick fiber identification by mixing a VFL signal into the test source. Compact, rugged, and ISO/IEC 17025 calibrated, it is ideal for singlemode certification, telecom, and FTTx applications.
