Optical network systems

What is a Certified Optical Network Engineer?

What is CONE?

CONA certified optical network associate logo The Certified Optical Network Engineer is OTT's advanced level optical networking certification that builds on the foundation provided by the CONA course. This programme will prepare you for the challenge of providing ever higher capacity that can start pushing at the boundaries of what is achievable with conventional fibre optic communications systems. Knowing these limitations and how they might be addressed is an important part of planning the development of critical networks for the future, but for some this future is already upon us! Not only do you have to provide enormous capacity, flexibility and scalability, but you also have to do it in a way that is reliable, affordable, low latency and energy efficient.

So on the CONE course you'll learn about the directions being taken by advanced optical transmission technology, but in the context of the world of efficient management and control enabled by SDN, NFV and related developments of white box solutions and OOLS (Open Optical Line Systems).

You'll learn about the motivations, capabilities and limitations of technologies that include coherent transmission systems that implement DP-QPSK and n-QAM modulation formats to deliver 100Gb/s+ DWDM channels. You'll investigate the role of advanced technologies like Flexgrid that breaks away from the traditional ITU DWDM grid that has served us so well, next generation CDC-ROADMs, new advanced fibre types and amplifiers for these new types of networks.

It's important too, to understand the role of state of the art electronics in enhancing optical communications using coherent detection, digitial signal processing (DSP), electronic dispersion compensation (EDC) and Forward Error Correction (including SD-FEC).

With more optical power going into our fibres then the dangers of entering into non-linear operational regimes need to be understood, avoided, mitigated or controlled.

When looking at some of the developments we'll be using OTT's WhizzieKit virtual optical networking system and going behind the scenes at WhizzieKit's development labs to understand the challenges and dilemmas being faced by equipment manufacturers as they develop the next generation of transmission systems. For example, what form factors should be used for pluggable optic transceivers? CFP, CFP2, CFP4, SFP28, QSFSP28, OSFP, QSFPDD...? are pluggables they way forward? What is the role of ACO or COBO solutions?

As with the CONA course, the advanced CONE course makes extensive use of case studies, real world scenarios and assignments to make the training come alive and to give you the opportunity to apply what you have learned. The assignment also acts as an assessment for certification together with the CONE exam that you'll complete on the course.
