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

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

Here be dragons

Pauline Rigby explores the roadmap for next-generation optical access

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

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

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

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’

F is for FPGA

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

Internet of everything

In less than a decade, everything could be connected to the Internet of Things. What impact will this have on the businesses of optical transport vendors, wonders Rebecca Pool

Digital signal processors meet Moore’s law

Silicon technology has powered rapid advances in coherent optical communication. Now silicon’s progress is set to slow, but that’s just one of many concerns the industry is preparing to overcome, finds Andy Extance

Securing the cloud networking supernova

The shift to cloud computing is placing great scrutiny on the security of data as it travels through the network. Jonathan Homa explains how optical systems vendors can help businesses to protect their data

 

Super-sizing the data centre

Warehouse-scale data centres are stretching the limits of current networking technologies. Dr Ioannis Tomkos describes how advanced optics can remove performance bottlenecks to enable the data centres of the future

Compatibles to remember

ProLabs wants to be as well known for optical modules as Kingston Technology is for memory chips, writes Pauline Rigby

Sharing of the wealth

As technology cycles accelerate, how will optical components and module vendors continue to fund advanced research and development? Pauline Rigby investigates

Optical networks underpin 5G

The European Commission has put optical networks at the core of its research programmes for 5G networks. Pauline Rigby reports

Blow by blow

David Stockton gives an account of past, present and future developments in blown fibre technology and equipment

Future passive

What will passive optical networks look like in future? Robert Roe explores some promising new research directions

A brighter future

FTTH Council Europe President Edgar Aker spoke to Fibre Systems about the new action plan to increase FTTH adoption in Europe

ROADMs move into the cloud

Reconfigurable optical add drop multiplexers will bring flexibility and efficiency to data centre interconnect transport networks, argues Coriant’s Bill Kautz

Redefining density

Corning’s Matthew Guinan considers how products that maximise density can help operators cope with the increasing amounts of fibre in their networks

Soft optics, hard photons

Geoff Bennett examines the evolution of coherent super-channels and how the use of software programmable modulation formats gives operators new options for network optimisation

Keen to clean

Beth Harlen spoke with Mike Jones, MicroCare vice president international, and Scott Wells, business manager Europe, about the importance of cleaning in the fibre-optics industry

Long-distance vision

Ian Davis explains how ultra-low loss and large effective area designs for optical fibre can enhance the operation of long-haul optical transmission in modern optical networks

Latin America embarks on FTTH journey

FTTH deployment in Latin America has suddenly accelerated and offers massive potential for growth. Robert Roe examines the unique circumstances in this interesting market

The problem with packaging

With packaging costs dominating the cost of optical transceivers, will silicon photonics ever provide the cheap, fast optical links that data centre managers crave? Rebecca Pool finds out

Blurred boundaries

How should the metro network be described? Jon Baldry considers how optical systems vendors are responding to the changing requirements in the metro market

Good grounding

 

AFL has expanded far beyond its origins as a manufacturer of optical ground wire, and now offers a broad portfolio of fibre-optic products. Robert Roe talks to Phil Edwards, president of AFL EMEA

The many paths of Asian fibre

The most prominent examples of FTTH deployment in the Asia Pacific region aren’t necessarily the most instructive. Benoît Felten explains why

Self-service bandwidth

Software control has finally reached the optical layer. Pauline Rigby talks to Infinera about its involvement in the first commercial deployment of a software-defined optical network

Search engines of change

Demand from Internet companies is remodelling the network equipment market. Andy Extance talks to telecoms market research firm Ovum about the consequences

Cable conundrum

Competition from fibre-to-the-home networks is putting cable operators under pressure. Robert Roe investigates the options available to cable operators wishing to upgrade their networks

Backhauling with fibre

Modern installation techniques and smaller, lighter cables enable more economical fibre deployment in mobile backhaul networks, writes Vanesa Diaz

Stacking the odds in favour of PON

Current technologies for passive optical networks are reaching their limits but, as Robert Roe discovers, making the right choice of next-generation technology is not easy

Can ocean cables go green?

Efforts to use submarine fibre-optic cables to gather important environmental data are off to a promising start, finds Andy Extance, but significant hurdles remain

Connecting the 
past to the future

Since starting out as a zinc die casting company more than 50 years ago, John Guest has diversified into many areas and is now very active in the blown fibre push-fit connectors market.
