When and why does polarization mode dispersion (PMD) compensation fail in 40G/100G+ coherent systems?

In this webinar, EXFO (a leader in field testing), and General Photonics (an expert in lab measurements) join forces to explain the reasons why PMD compensation might fail or be ineffective. Also, some recommendations are provided on how to reduce the risks of these failures. This webinar will cover the following topics:

• The concepts of PMD, Differential Group Delay (DGD), and State of Polarization (SOP)
• The limitations of PMD compensation capabilities in coherent receivers
• The PMD-related tests performed in the laboratory to optimize PMD compensation algorithms
• The PMD tests carried out in the field to identify PMD issues in advance and reduce their frequency
