Dense Wavelength Division Multiplexing (DWDM) is a key component of the world’s communications infrastructure. The tremendous growth in telecommunications services is possible today in part through optical networks, where DWDM systems allow much greater bandwidth over existing optical systems. For anyone involved with telecommunication and information technology, understanding this technology is a critical requirement.

In this DWDM Advanced Training course, you will learn the technology, architecture, and applications of DWDM. We will review DWDM system components as well as the end-to-end optical network design process. You will also learn aspects of optical control, network management, and practical deployment issues such as optical submarine cable and access networks. This comprehensive review will provide all the knowledge and skills necessary to design and implement DWDM systems.
