DWDM Training – Advanced (TR-DWA)

Course Information

This course provides an advanced technical overview of DWDM training and optical networking concepts. One of the major issues in the networking industry today is the rapidly increasing demand for greater bandwidth. With the development of optical networks and the use of Dense Wavelength Division Multiplexing (DWDM) technology, a new and crucial milestone is being reached in network evolution.
