Optical Transport Networks: SDH, OTN & DWDM
Understand the optical backbone that carries traffic between cities and data centres.
About this course
Understand the optical backbone that carries traffic between cities and data centres. You will learn SDH and OTN framing and multiplexing, DWDM wavelengths and amplifiers, protection and restoration, and how packet and optical layers work together in modern transport networks.
What you'll learn
- Describe SDH and OTN framing and multiplexing.
- Explain DWDM channels, amplifiers and optical budgets.
- Compare protection and restoration schemes.
- Describe how packet and optical layers interwork.
- Read alarms and performance data on transport networks.
