HAND-IN- HAND
HOW WILL THE NEXT- GENERATION OF OPTICAL NETWORKS PROVIDE THE CAPACITY TO SUPPORT UNWAVERING INCREASES IN TRAFFIC, AND DOES ONE SOLUTION REALLY ‘FIT ALL’?

s the world struggles to setle into the ‘new normal’, today’s optical networks need to be flexible in their architecture blueprint, while
adapting to new technologies to provide the kinds of new capacity and service options to meet accelerated demand for higher bandwidth. Speaking at the virtual NGON DCI event,
as part of a panel discussion on the topic, Timothy Munks, senior principal analyst at Omdia said: ‘2020 was a very challenging year for optical networks. We’ve had the “work, learn, play” at home and what we are seeing is sustained bandwidth use throughout the whole day at former peak levels. For example, the
average subscriber in North American cable TV networks between 9am and 5pm is about 6.3G, and that’s up some 41 per cent.’ Despite this, Munks said that in general the
networks have performed ‘amazingly well,’ with limited supply line disruptions between March and May. ‘For the most part,’ said Munks, ‘these were overcome and we’re not seeing supply line disruptions anymore.’ Even without the pandemic-factor, however,
the market continues to be driven by the need to increase capacity and lower the cost-per transported bit. Much of the work to do this focuses on adding L-band and increasing C-band. ‘Te thing you want to do most,’ said Munks, ’is get as much out of the fibre
