The Challenge

Formerly network traffic was about voice calls carried over circuit-based networks in a predictable tied network connection between pairs of endpoints. Now most network traffic is packet-based, generated by many services and applications in unpredictable traffic patterns, with widely varying and more stringent demands on bandwidth and data transmission performance.


The a rapid increase in the explosion of digital traffic, driven by mobile applications, multimedia services, social media, cloud computing, and VOIP services and now the proliferation of 5G Networks means that demands for ever increasing low-latency capacity has never been greater, and is growing rapidly.

With billions of IoT enabled devices predicted to come online, not just in homes, but within industry, agrochemical, health, automotive, mass transit, and almost every conceivable business serving both B2B and B2C markets, the need for rapid, reliable and failsafe connectivity for backaul and fronthaul to serve localized data demands will rise dramatically.

All of this inevitably expands the need for Optical transport technology, In addition the need for increased capacity in carrier passive optical networks, (XGPON) and a greater need to deploy fibre to the home and premises (FTTX) – Ethernet technology is also evolving, as the speeds attainable over traditional ethernet cable technology are increasing from 10MBPS in 1983, to Gigabit Ethernet in 1998, – With the development of optical interfaces Ethernet can extend its range into carrier systems and can run at 10Gigabits, 100Gigabits and perhaps eventually up to 1 Terabit per second.

Our subject matter experts can instruct or consult on all levels of the technologies which underpin 21st century optical transport networks.

Customer satisfaction is crucial to our business

Very good three days. The instructor was clearly a subject matter expert, and took the effort to develop materials on virtualization and disaggregation models. Very professional.
Sales Engineering Director
The instructor was an excellent with a wealth of experience, although I worked in GPON for some time I did get many new insights.
Senior Sales Engineer
Take a bow for delivering the content. We appreciate this is difficult and not as easy as being in person F2F. Thank you. It was delivered very well.
Regional VP
Excellent and highly relevant training subjects, thanks.
Technical and Sales Account Manager
We appreciate all the hard work that has gone in to put this course together. Thanks!
Director Technical Services
Thanks that was a great in depth training session.
