Polarisation Mode & Chromatic Dispersion Testing

This 3-day course is designed for fibre optic installation engineers, project managers and those working within the telecommunications networking field.

Providing a comprehensive insight into polarisation mode dispersion and chromatic dispersion testing, this theory and practical based course covers the critical parameters that need to be adhered to in order to correctly measure and install the appropriate PMD and Chromatic Dispersion equipment and cabling. Test results will also be examined and interpreted in order to learn how to assess the potential impact on system design and overall performance.
