This two-day class combines classroom lecture and hands-on testing skills to provide an understanding of the principles behind building and maintaining high speed optical networks. Key parameters such as polarization mode dispersion (PMD), chromatic dispersion (CD) and optical return loss (ORL) need to be calculated in order to evaluate system capabilities and network upgrades to higher bit rate systems.
