Course Description

The growing demand for bandwidth necessitates the transmission of large amounts of data in optical fibers. In long distance networks, such as metropolitan networks, data center interconnects, terrestrial long haul and submarine networks, this is achieved by multiplexing multiple data channels at different wavelengths into a single optical fiber.

DWDM training provides an overview of Dense Wavelength Division Multiplexing (DWDM) network planning, architecture, design, protocols, testing and implementation.
