From SDH to Optical Transport Network (OTN)

Big spools of optic wire

This course guides participants through the migration from SDH transport technologies to Optical Transport Network (OTN) technologies.

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 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, Internet of Everything, 5G backhaul, cloud computing, Smart cities.

The course also covers the key OTN technologies, components (Active, Passive and Optical), architectures,
parameters and standards involved. An introduction into OTN Planning is also included as part of this course

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.

This course acts as a pre-cursor to Telefocal’s DWDM and optical networking for Metro and Long Haul.
