Encircled flux is a metric for defining launch conditions on multimode optical fibre that reduces measurement uncertainty in link loss measurements shown by different test equipment. Adrian Young, senior technical support engineer at Fluke Networks, explains how to take account of encircled flux in Tier 1 optical loss measurement

Robert Roe goes over the top, in his second analysis of some of the themes to emerge from OFC 2014
While the 12,700 visitors to OFC 2014 milled around the high-tech displays by the 550 exhibitors, the minds of some of the industry leaders were fixed firmly on the films that the American public likes to watch. Or, more precisely, the way in which the American public likes to watch its films.
At the OFC in San Francisco, Robert Roe heard concerns about IT and the back office figuring almost as large as issues of high technology.
Although the 12,700 visitors to OFC 2014 saw all manner of technology on display from the 550 exhibitors, it was something less tangible – software – that became a dominant theme of the event.
The Consumer Electronics Show indicates that 2014 will be the year when connected devices will generate increased demand for fibre to the home, says Nadia Babaali, Communications Director, FTTH Council Europe
A recent study has predicted fast growth in data traffic on metropolitan access and aggregation networks. Transmode's chief technical officer Sten Nordell offers a perspective on the situation
In December, as reported in Fibre Systems, a study predicted that there will be a 560 per cent increase in data traffic on metro cable networks, driven by an increased demand for video and the continued proliferation of data centres.
A fibre-to-the-premises (FTTP) roll-out would be of more financial beneficial to Britain than the HS2 rail line, according to an IT entrepreneur.
The coalition government is planning to spend upwards of £45 billion on the high speed railway – but bringing the country’s businesses access to superfast broadband through fibre-to-the-premises (FTTP) and fibre-to-the-home (FTTH) would be cheaper and financial beneficial to the country, says Scott Fletcher, chairman of UK cloud infrastructure specialists ANS Group.

When it comes to innovation, Sweden punches above its weight. Sweden was ranked as the most innovative country in Europe in September 2013, using a new benchmark created by the European Commission. The “indicator of innovation output” measures the extent to which innovative ideas from several key industry segments – such as the environment, energy, ICT, health, and high-technology industries – are able to reach the market.
Poor internet connection speeds are disadvantaging companies in the entrepreneurial heart of Britain, according to a European politician.
James Elles, the Conservative MEP for the South-East has described how European leaders met in Brussels to discuss a key initiative of the European Commission – the Digital Agenda for Europe.
Tom Wilkie reflects on some of the themes that emerged at ECOC
Datacentres, testing, and how to pay for next-generation transmission networks were among the themes that dominated the 39th European Conference and Exhibition on Optical Communication (ECOC), held at in London UK at the end of September.
Criticism of the UK Government's rural broadband programme lacks understanding, according to a telecommunications expert.
In light of the recent and less-than-enthusiastic Public Accounts Committee report on rural broadband, Matthew Howett, principal analyst for telecoms regulation at Ovum, explains how it raises valid concerns but also shows a lack of understanding of some of the basics.
The European Commission has missed an opportunity to have a better-focused fibre policy in its Digital Single Market proposal by continuing to ignore the key issues, according to the FTTH Council Europe.
The council says there is too little FTTH investment, and that the proposal fails to set out a vision of how the industry can accelerate investments for the benefit of the broader economy.
Claims that European countries cannot afford the roll-out of fibre to the home (FTTH) networks may not stand up to close scrutiny, according to the director general of the FTTH Council Europe.
Hartwig Tauber said that, despite seemingly 'insurmountable' obstacles of shareholder demands, increasing competitive pressure and the economic downturn, there is plenty of money available to invest in such a project.
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
Robin Mersh takes a look at how the industry is creating next-generation optical access fit for 5G
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
