Otdr Test Curve A Minor Fault B Normal C Serious Fault

How to use OTDR to test the splice loss of optical fiber cables

It works like "radar for fiber optics," sending light pulses down the fiber and analyzing the reflected light to measure loss, locate faults, and verify installations. Proper OTDR usage is essential for network commissioning, maintenance, and troubleshooting. An Optical Time Domain Reflectometer (OTDR) is the most powerful tool for characterizing fiber optic networks. Clean Connectors: Inspect and clean all bulkheads and patch cords using professional fiber wipes. Deploy Launch Fiber: Connect an unconditional launch cable (>500m) to eliminate the initial dead zone. It can verify splice loss, measure length and find faults. Later, comparisons can be made. OTDR testing analyzes fiber optic cable performance from end to end by testing components along the cable, including connection points, bends, and splices.

OTDR measurement curve of optical cable breakage

The OTDR display shows this as a continuously decreasing curve – the further the light penetrates into the fiber, the weaker the backscattered signal becomes. This article shows in detail how municipal network operators can optimally use OTDR technology to inspect their networks in accordance with standards, precisely localize faults and ensure the highest quality in the long term. It can verify splice loss, measure length and find faults. The correct configuration of wavelength, pulse width, range, and averaging is key to obtaining reliable traces. Optical fiber cables are tested for attenuation using the cut back method (TIA 455-78) or back reflection method (TIA 455-8).
