Dispersion Testing (CD and PMD)

Dispersion characterization and spectral testing (CD-PMD)

An overview of general dispersion phenomena occurring in fiber-optic communications, as well as the problems caused specifically by polarization mode dispersion (PMD) and chromatic dispersion (CD). The course also describes the internal workings of EXFO’s PMD and CD analyzers and explains how to interpret the result obtained with the instruments. Hands-on exercises on PMD and CD analysis and result interpretation are also included in the curriculum.

Offered only in US by Light Brigade

Light Brigade

Since 1987, Light Brigade has trained more than 85,000 students in courses ranging from basic fiber optic theory and practices to comprehensive design and installation courses. We are not just theory based. Our hands-on labs reflect real-world tasks, providing the practical training needed to improve operational efficiencies by reducing costly errors.  We offer several methods for training and can tailor any program to suit your needs.
