STANLAY SOT 300 OTDR – 36dB Fiber Tester with OPM, VFL & Link Map

The STANLAY SOT 300 OTDR is a multi-function fiber testing device designed for optical cable installation, network maintenance, troubleshooting, and project acceptance. It is suitable for FTTx, CATV, city/metro fiber networks, and campus networks where reliable fiber measurements are required. The tester combines OTDR testing with an Optical Laser Source, Optical Power Meter, and Visual Fault Locator, giving technicians several essential tools in one compact unit. Its 7-inch multi-touch color screen provides a clear interface for field operation. The built-in Link Map presents fiber elements such as connectors, splices, macro-bends, splitters, and fiber ends in an easy-to-follow visual format. Pass/fail settings can also highlight problem events, helping technicians identify areas that need attention. The SOT 300 series is available in different configurations with 32/30dB, 36/34dB, or 36/34/34dB dynamic range, depending on the model. Key Features Multi-Function Fiber Testing – Combines OTDR, OLS, OPM, and VFL functions. Visual Link Map – Shows important fiber events in an easy-to-read network view. Pass/Fail Analysis – Highlights failed measurements and problem events. Long Battery Operation – 10400mAh lithium-ion battery supports extended field use. Wide Application Range – Suitable for FTTx, CATV, metro, and campus fiber networks. Touchscreen Control – 7-inch multi-touch display makes field operation convenient.
