After completing this course, participants will be able to:
- Understand optical fiber transmission systems
- Appreciate SDH technology (including transmission hierarchy & network components)
- Comprehend DWDM technology (including transmission systems & network components)
- Describe OTN architecture and protocols
- Recognize how OTN can ensure transportation, multiplexing, routing, supervision and survival of customer signals through a treatment executed primarily in optics.
An Optical Transport Network refers to a series of standards created to combine the benefits of SONET/SDH with the bandwidth-expanding capabilities of DWDM in order to build more network functionality into optical networks – and with considerable costs savings.
Migration from SDH to Optical Transport Network (OTN) has been happening for a number of years now – as operators recognize the need to provide network capacity and functionality to cater for the dramatic changes occurring in the telecommunications landscape e.g. big data, IoT, 5G backhaul, cloud computing, Smart cities.
This training guides participants through the migration from SDH transport to OTN technologies.
It covers key OTN technologies, components (Active, Passive and Optical), architectures, parameters and the standards involved. An introduction to OTN Planning is also included as part of the course agenda.
- Good understanding of telecommunications transmission principles.
- Prior attendance at Course C1: SDH/DWDM Fundamentals is highly desirable
Who Should Attend
Fiber core network supervisors, planners, technicians, graduates and apprentices, strategic and technical telecommunication managers, consultants, IT professionals, systems engineers, marketing and sales professionals plus other telecommunications workers who plan on using, evaluating, designing or working with optical transport networks.
