Autumn 2021 - Optical Connections Magazine


BACK TO THE FUTURE Welcome to the autumn edition of Optical Connections and to the return of ECOC in its physical form. Both the magazine and the expo have plenty to offer, reflecting the very latest developments and trends in the fibre optic communications industry. In this issue, we’re taking a deep dive into optical networking technologies as we talk to Lumenisity’s VP, Marketing and Sales, Tony Pearson, about the company’s hollow core cable, which has the potential to massively increase transmission speeds. Lumentum’s CTO office’s David Lewis, takes an in-depth look at the connectivity challenges operators face when designing 5G fronthaul to handle the expected high throughput that the technology will require. We also talk to Nokia’s marketing chief Nick Cadwgan about the transformational changes taking place in both the mobile networking layer across the radio access network and the mobile transport core. Veteran journalist John Williamson examines the numerous attractions for optical network operators and service providers offered by Reconfigurable Optical Add Drop Multiplexers (ROADMs) and regular contributor Antony Savvas looks at the challenges faced by network operators when considering which aspects of network management can easily be automated. Meanwhile, at the customer end of the network, we talk to Emtelle and InCoax about two possible alternatives for easing the pain of providing fibre broadband services to customers living in Multiple Dwelling Units (MDUs). There’s also a full preview of ECOC 2021 in this issue along with selected presentations for the ever-popular Market Focus sessions and a full list of categories for the ECOC Exhibition Industry Awards, the winners of which will be announced and the presentations made in the Product Focus Theatre on Tuesday 14th September, at 3pm. New for this year’s ECOC is the Focus Media Zone, which features a theatre where visitors can watch webinars and presentations and back by popular demand are three FTTx Zones showcasing a range of fibre- related products. But that’s not all we’re excited about! The new Optical Connections webinars have been a great success this year and on page 28, you can find out about previous sessions, how to watch any you might have missed, and which subjects will be covered in the future. Also new is the Telecommunications, Optics and Photonics Conference, which will be held in conjunction with Optical Connections, in Central London on 14-15 February 2022. It will cover topics including telecoms, data centres, photonics and free space optics. Check out our website and emails for further details, including the call for papers and registration. The team at Optical Connections and Nexus Media Events look forward to seeing you in Bordeaux in September and wish you a safe and productive ECOC 2021.
