DWDM Advanced Training | Dense Wavelength Division Multiplexing Training Course Description

In this DWDM Advanced Training | Dense Wavelength Division Multiplexing 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. With DWDM Advanced Training | Dense Wavelength Division Multiplexing Training Course, 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.

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.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
