Learning to shape the future

To exploit machine learning and artificial intelligence, optical transmission systems require greater automation, finds Andy Extance

A new era for Ethernet

John D'Ambrosia explains how various Ethernet standards developed in IEEE 802.3 over the past decade are enabling a myriad of products to find their way into deployment throughout the Ethernet eco-system

Taking centre stage

The data centre has created demand for an infrastructure that provides greater bandwidth and higher data rates, but how has this impacted the market for optical components? 

Crunching the 100G serial numbers

Cost and compatibility can make a compelling case for pushing 100Gb/s bandwidth over a single optical channel, both as individual links and supporting 400Gb/s Ethernet, finds Andy Extance

Access granted

Robin Mersh takes a look at how the industry is creating next-generation optical access fit for 5G

The shape of things to come

Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov and Dr Yin Wang

Terrestrial extra

With the advancement in high-speed optics and modulation techniques bringing fibre optic systems for terrestrial networks in line with submarine systems, it’s little surprise that the industry is approaching a new era of terrestrial and submarine cable integration. Keely Portway finds out

Testing the ECC

How has the strength of the Electronic Communications Code been tested by the dispute between Virgin Media and Durham County Council? Brian Wake offers his view*

Learn from experience

As data demand ramps ever higher, researchers are looking to innovative amplifier designs to help transport a broader light spectrum through optical fibres, finds Andy Extance

The final frontier

Duncan Ellis shares his views about the increased focus on automation from network operators, and how the physical layer has so far stubbornly resisted the move

The long goodbye

Switching off copper networks where fibre has been deployed is the end game, so why are so few operators doing it, wonders Pauline Rigby

A time to skill

With demand for fibre to the premises increasing, Keely Portway looks at the role training plays in ensuring installation skills remain available to meet this growing demand

Magic number

Ana Pesovic discusses the three core elements required in creating a smart city

For centuries, humanity has looked for new ways to build smarter cities; ways that improve city operations, grow the economy and create a better place for people to work and live. From the aqueducts in Rome to the more recent technology innovations that help simplify the challenges of urban life, cities are, and have been, getting smarter throughout history.

In advance

Vanesa Diaz discusses building advanced cable TV networks for gigabit services

CPR: lifesaver or liability?

Six months after it became mandatory for copper and fibre cables supplied to EU/EEA member states to comply with the Construction Product Regulation and carry CE marking, Keely Portway asks what, if any, effect this has had on cable suppliers

The Rise and fall of the Australian NBN

Green Nylon jacketed 576 fibre optic ribbon cable at an installation site used for the backbone of the NBN in Australia

Benoît Felten takes a closer look at what went wrong with Australia’s ambitious National Broadband Network

A life with light

January of this year saw Jerry Rawls step down as chief executive of Finisar, a company he had grown from obscurity to worldwide success. He talks to Rebecca Pool about building his empire, the firm’s new CEO and a future that could include Oclaro*

The state of telecom in 2017

As 2017 draws to a close, Scott Wilkinson looks ahead to what’s in store for the optical communications industry in 2018

Infrastructure investors pour money into British broadband

Britain has a reputation as a backwater when it comes to fibre-optic broadband connections that reach directly into consumer’s homes. Currently, only two per cent of households in the country have access to full fibre connections. But that looks set to change. This summer, some £500 million of equity and new debt have been invested in alternative network providers in the UK.

Getting the measure of Viavi

Oleg Khaykin, CEO of Viavi Solutions, speaks candidly to Fibre Systems about how to compete in the challenging world of communications test and measurement

Fibre and cable for the cloud

Hao Dong describes how innovative optical fibres and cabling could provide substantial benefits for connecting data centres across a wide range of distances

Show Preview: ECOC 2017

ECOC is the place to be to discover the latest technological and commercial innovations in optical components and networks. Here we highlight some of the exhibitors and events taking place in the exhibition hall.

The age of time-sensitive optical transport

Optical networks are playing an increasingly important role in the distribution of precise timing signals and synchronisation with sub-microsecond accuracy. Michael Ritter explains

Squeezing the margins

Systems vendors are using intelligent software to squeeze more performance from optical networks. Pauline Rigby reports on developments at OFC 2017

The battle of the modulation schemes

Oclaro's Adam Carter and Dan Tauber examine which modulation schemes – DMT, PAM4 or coherent – are likely to prevail in the race to higher-speed transmission for more cost-sensitive links

How telecom can combat climate change

BT, Telefonica, Telia Carrier and the Global e-Sustainability Initiative explain how the communications industry is reducing carbon emissions, even as data consumption escalates

A quantum of security

Commercial development of quantum key distribution is coming just in time to meet the security threat from quantum computers, finds Andy Extance

Here be dragons

Pauline Rigby explores the roadmap for next-generation optical access

F is for FPGA

Pauline Rigby speaks to Xilinx about the burgeoning opportunities for programmable devices in data centre and cloud computing markets

Breaking the glass ceiling

Scaling the capacity delivered by optical systems is becoming increasingly difficult, even as data traffic continues to grow exponentially. Pauline Rigby investigates new techniques that could postpone the inevitable ‘capacity crunch’

Silicon photonics extends its reach

Dr Marc Bohn gives a systems vendor’s perspective on the emergence of silicon photonics based components in coherent metro and long-haul optical networks

How to clean fibre-optic connectors

Correct cleaning of fibre-optic connectors is the single most powerful practice that network operators have to future-proof their network, argues Ed Forrest
