Optical Fiber Transmission Networks Using DWDM Technology

Dense Wavelength Division Multiplexing (DWDM) is an optical multiplexing technology used to increase bandwidth over existing fiber networks. DWDM works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber. The technology creates multiple virtual fibers, thus multiplying the capacity of the physical medium.

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.

So for those who aspire to start career in telecom companies, it is quite rewarding to invest in the DWDM technology. For those already working in telecom companies providing different data and voice service, this will enhance their portfolio and career prospects.

This DWDM training is comprehensive and indepth, so that you may get started with this DWDM technology as soon as possible. This course is designed to provide you with necessary functional knowledge possible in shortest possible time.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
