Optical Connections Magazine Autumn 2018

CONTENTS

As ECOC, the largest conference on optical communication in Europe and actually one of the largest such gatherings events in this field worldwide, rolls around to Gothenburg (and as CIOE 2017 addresses the latest developments in opto-electronics at the Shenzhen Convention & Exhibition Center in China), this issue of Optical Connections provides a handy companion piece to the events, with news and features on many of the hot topics under discussion. Hot topics this year include fibre devices and amplifiers, integrated devices and processors, digital techniques, subsystems and network elements, point- to-Point Transmission Links as well as core, metro and, of course, data centre networks. Gothenburg, in the heart of Scandinavia, is an apt location because Nordic countries have a great tradition of developing optical telecoms technologies – as Danish industry expert Per Danielsen reports on page 18. Hybrid optical and wireless networks oering flexible benefits are described by John Williamson, who says that hybrid networks in broadband access and distribution networks oer flexibility in network design; increased service variety and ultimately greater customer satisfaction. See page 22. With standards for 5G wireless networks still being finalised, there are many diverse options for fibre’s future role, says Andy Extance: optical technologies are supporting not only fronthaul and backhaul, but also crosshaul. Read all about it on page 24. Hardly a day passes without a media report of a network security problem – hacking, data leaks, shutdowns of company networks and so on. So how can better security be designed into optical networks? Ellen Manning investigates this hot topic on page 28. Software innovations in management are changing the nature of optical networks, as was discussed at the latest Next Generation Optical Networks conference in Cannes. Antony Savvas attended and reports for us on page 30. We also have a specially contributed article from Intel on the latest developments in silicon photonics to boost data centre interconnectivity; specialist Robert Blum reports on page 33. Another contribution from Chris Dunford of Exfo outlines best practice for testing scalable G.Fast deployments, on page 44. Enjoy the shows – and enjoy Optical Connections. We would love to hear your feedback on both.
