Fibre broadband boosts US home values, study finds


During its conference this summer, the FTTH Council Americas released a white


paper finding that access to fibre-to-the-home (FTTH) may increase a property’s value by up to 3.1 per cent. The study, conducted by Gabor Molnar and


Scott J. Savage of the University of Colorado at Boulder and Douglas C. Sicker of Carnegie Mellon University, found that adding FTTH to a home raises its value 1.3 per cent, while upgrading the FTTH connection from 100Mb/s to 1Gb/s adds another 1.8 per cent. Using the National Broadband Map and a


nationwide sample of real estate prices from 2011 to 2013, the study’s authors investigated the relationship between fibre-delivered Internet services and property prices. The boost to the value of a typical home – $5,437 – is roughly equivalent to adding a fireplace, half of a bathroom or a quarter of a swimming pool to the home. Looked at another way, gigabits add the


greatest value. The study found that, for homes where gigabit broadband was available, transaction prices were more than seven per cent higher than homes located where the highest speed available is 25Mb/s or lower. A similar study published last year by


researchers from Imperial College Business School and the London School of Economics and Political Science (LSE) analysed the value of broadband to English households, looking at the link between property prices and broadband availability using statistics compiled over a 15-year period, from 1995 to 2010. They discovered that upgrading from dial-up to an 8Mb/s DSL connection could increase the


price of an average UK home by 2.8 per cent. An additional increase to 24Mb/s has an incremental price effect of one percent, according to their report: Speed 2.0. Evaluating Access to Universal Digital Highways. The US research improves on this data by


using new, higher measures of speed as well as availability of fibre, which is more widely available in the US than in the UK. The FTTH Council Americas says the studies


add to a growing dossier of evidence for the consumer benefits from widespread access to fibre broadband Internet. A number of studies have linked broadband networks and new investments in such networks to improved economic performance.


Last year, the FTTH Council released a study


finding higher per capita GDP in communities where gigabit Internet was available. Infrastructure investment, job creation, entrepreneurship, and companies relocating or expanding to your city are all manifestations of this growth. ‘The evidence is mounting: investment in fibre


improves the economic performance of a community as well as its quality of life,’ said FTTH Council president and CEO Heather Burnett Gold. ‘Around the United States, leaders at the local level have started to think about how their community’s Internet infrastructure is a catalyst for economic, educational, and governmental innovation.’


Orange reaches record 38.4T transmission in the C-band For Orange, the objective was to


WDM 2015, NICE, FRANCE – French operator Orange has reported a successful field trial transporting 38.4Tbps over 762km (472 miles) on its installed network, from Lyon to Marseille and back again. This is the highest aggregate capacity ever reported for optical transmission in the C-band, the operator says. The trial was carried out as part of the project SASER (Safe and Secure European Routing), part of the CELTIC-Plus European research initiative, and under the subproject SIEGFRIED.

demonstrate that its installed fibre-optic infrastructure is able to transport multi-terabit capacity. For vendor partners Coriant, Ekinops, Keopsys, and Socionext, the aim was to validate their next-generation optical transport technologies to show that they are compatible with the operational constraints of a real, live optical network. Designed to showcase upcoming


technologies, the field trial employed terabit and faster super-channels, implemented by Coriant. In fact, Coriant


claims it is the first ever field demonstration of full flexi-rate and flexi-grid transmission – with modulation schemes ranging from QPSK to 64QAM – which were based on prototype versions of Coriant’s new CloudWave Optics software. In addition, the coherent


transmitters and receivers used the latest generation of ultra-high-speed analogue-to-digital converters with a sampling rate of 92GSa/s, developed by Socionext, the company formed by the amalgamation of the systems LSI


businesses of Fujitsu and Panasonic. A variety of advanced modulation


formats were put through their paces, including 24 super-channels at one terabit via DP-16QAM (total of 24Tb/s), 32 super-channels at 1Tb/s via DP-32QAM (32Tb/s), and 32 super- channels at 1.2Tbps via DP-64QAM (achieving the record 38.4Tb/s). The distance of 762km is more than twice the distance previously achieved for 32QAM, and the first demonstration of 64QAM transmission over a regional distance, according to Coriant.
