Keely Portway looks at how probabilistic constellation shaping (PCS), could address the limitations associated with conventional coherent modulation, and why it is fast becoming an industry disruptor

Bridging the gap

PIA has proven its value in a project to build a carrier-independent dark fibre route between Bristol and South Wales in the UK. Mark Weller explains

Going for gold

Geoff Bennett evaluates how 50 years of innovation in optical communications has more recently helped to bring light from the shadow of Covid-19

Sum of its parts

Guillaume Baral outlines some of the significant benefits of adopting a more agile, modular approach to product development for fibre networks

The future's bright

Keely Portway evaluates some of the latest trends when it comes to multimode fibre, and looks at why it is currently something of an industry bright spot

5G fuelled by full-fibre diet

A look at how the kind of full-fibre infrastructure that will be essential to support 5G can be realised in line with roll-out targets

A deep impact?

A round-up of the impact of Covid-19 on the optical communications industry from a number of leading analyst firms

Uncharted territory

Niall Looney summarises his business experience to date in dealing with the current Covid-19 pandemic, from a network design consultancy’s point-of-view

Graphene dreams

Graphene could transform networks if its remarkable properties can sustain a viable supply chain, finds Andy Extance

A la mode

Keely Portway takes a look at the future for multimode fibre and the opportunities it presents to the data centre market

Mixing it up

A look at building future-ready terrestrial networks with hybrid optical fibre cables, with Sergei Makovejs and Matthew Guinan

The fast lane

Raf Meersman offers three routes to 5G that could ensure less capital and operational expenditure for operators, for all of which, convergence is key

Teaming up

Keely Portway finds out how optical networking interoperability is achieved through industry collaboration

Homeward bound

Keely Portway takes a look at what needs to be done over the next 12 months to move toward the goal of copper switch-off

Clean as a whistle

Ed Forrest looks at the impact of primary and secondary contamination on fibre optic connection surfaces

Fibre optic cleaning techniques are based on the removal of types of dust or oily matter. Single soils are relatively easy to remove compared with ‘combination soils’ that might be dust, combined with human body oil or hand lotion. 

Have your say

Fibre Systems speaks to a lead design engineer and a fibre planner to find out about the day-to-day challenges they face on the front line

Making a deep impact

Keely Portway looks at the latest developments in submarine networks, and the issues and trends shaping the market

Pumping up the PIC volume

There are many challenges to overcome to provide quick and efficient characterisation of photonic integrated circuits, finds Andy Extance

Around the bend

Keely Portway takes a look at the next generation of bend-improved fibres, and how they can be best used to future-proof networks

Quality Control

Creating an invisible network is the next step in connectivity, so it is important to put quality, rather than speed at the heart of broadband experience, says Robin Mersh

Measured growth

The importance of fibre-optic test equipment has increased in recent years, as global fibre deployment ramps up. This was evident in some of the latest product developments demonstrated at recent industry events, and also shown in the most recent market research predictions

Small wonder

A new implementation agreement for low-power consumption will see small modules push technological barriers, finds Andy Extance

Full potential

5G is the talk of the telecoms industry, with 5G networks launching in the US and South Korea. But many don’t realise that 5G isn’t possible without fixed high-speed and high-density fibre connectivity, says Mikael Sandberg

The simple life

Scott Modha takes a look at how the right technique goes a long way, and network operators could benefit from simplified microduct network deployments

Flexible friend

Network core flexibility will become just as important as capacity for future networks, and coherent solutions could be key to accommodating changing traffic flows, argues Eugene Park

Power of good

Power over Ethernet (PoE) could help service providers adapt to the opportunity provided by IoT in order to remain competitive, argues Ankit Agarwal

Down to the wire

Cabling infrastructure will be vital in the deployment of 5G networks, meaning that the wireless will still depend on wires, says Jean-Jacques Sage

The smart money

Artificial Intelligence is a hot topic right now, with the potential to help improve efficiency both across the network, and from a cost perspective. Kailem Anderson vice president for software and services at Blue Planet, a division of Ciena, speaks to Fibre Systems about the role of AI in operator networks

Up to code

The European Electronic Communications Code has been finalised and formally adopted. How will it aid European fibre deployment, and what factors could impact the end goal of copper switch-off? Keely Portway finds out

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? 

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

Learning to shape the future

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

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*

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

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

Access granted

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

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

In advance

Vanesa Diaz discusses building advanced cable TV networks for gigabit services

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.
