Practical assessment and demonstrations tasks provided using the VanGuard Data OTDR Emulation software


VGD301: Advanced OTDR Trace Analysis: (Licensed Access Only) A deep dive into OTDR trace analysis covering all aspects of how to interpret and measure fibre quality from the trace. Includes measuring quality, distance and attenuation of reflective and non-reflective events. Practical assessment and demonstrations tasks provided using the VanGuard Data OTDR Emulation software


VGD402: Advanced OTDR Testing Concepts: (Licensed Access Only) For highly experienced OTDR operators looking to better understand concepts such as optical reflectance and back scatter, pressure points, gainers and ghosts. Including their causes and how to measure and identify from an OTDR trace using techniques such as multi-wavelength and bi-directional trace analysis. Practical assessment and demonstrations tasks provided using the VanGuard Data OTDR Emulation software
