Apart from holidays and sunshine (unless you live in the UK), summer means we’re in the thick of the conference season. In this issue, we look at some of the topics that will be up for discussion at many of the shows, as well as the issues which are facing the industry as it moves into an era of expansion. Ellen Manning’s feature Sti ening the Backbone looks at the growing investment in national networks as consumer demands and the availability of new technologies drive operators to expand their national backbone fibre networks. Across Europe, the US, Africa and the Middle East, backbones are being replaced by fibre on a massive scale and FTTP is becoming a reality for a rapidly growing number of households and businesses. The move from coaxial to fibre networks is not an end in itself however and Kevin Bourg, optical network architect at Corning Optical Communications discusses how hybrid coax/fibre network evolution can lay the foundations for full migration to FTTH. There is a potential threat to the ubiquity of FTTP however and in this issue, we look at the growing popularity of Fixed Wireless Access for last-mile connectivity. The expansion of the fibre market and the need for more speed and capacity is having other ramifications too. Network vendors are looking for ways of making these increasingly complex networks more e cient. In our exclusive interview with Nokia’s head of IP Transport, Sam Bucci talks about the company’s new Photonics Service Engine which automatically selects the appropriate modulation scheme for any particular application and in the process, greatly increases the capacity of new and existing networks infrastructures. Automation is also becoming a hot issue both at the device level and for network infrastructure management. John Williamson looks at the intensive component, product and system developments that are currently underway, with producers and manufacturers looking to improve the logistics, performance and economics of optical networks. Developments in SDN are also impacting on the e ciency of fibre-optic networks. With network speeds exploding through 100G, 200G and 400G to cope with tra c demands, writes Anthony Savvas, consumers are expecting to pay the same or even less, for more and more bandwidth and so flexible network management systems are now being used to cope with this scenario. The growing tendency to connect multiple data centres is having ramifications across the industry and John Williamson explores the changing nature of the data centre interconnect market, the projected growth in equipment revenues, the automation of network management and the move away from proprietary solutions. This theme is also examined by Ryan Yu, vice president of business development and GM of optoelectronic solutions at Oplink, who discusses in depth the possibilities for connecting hyperscale data centres. So, there will be plenty to talk about at the upcoming industry events and on the subject, as the newly-appointed editor of Optical Connections, I will be attending AngaCom and NGON in June and I look forward to meeting with as many of our loyal readers and supporters as time allows. It’s going to be a great summer! Summer is here!
