EXFO will team up with Telebyte, Alcatel-Lucent, Sagemcom and ADB at Broadband World Forum 2014 for a live multi-vendor FTTN VDSL2 vectoring demonstration. Attendees will be able to see the qualitative and quantitative effects of interferences such as impulse noise, RFI, mechanical interruptions, and more, under real-world conditions. The demonstration will then show how to tackle such impairments with the latest advances in VDSL2 Vectoring testing technologies.

With the rise in next-generation mobile network rollouts and social media, and a majority of subscribers who are now using smart phones to access data and voice services, mobile network operators are experiencing continued rapid growth in data traffic volumes across their networks. In the wake of the big-data explosion, they are looking to virtual network operations and cloud-based service offerings to drive new levels of operational efficiency, flexibility and cost optimization.

Webinar of the Week Blog Series | Ever since the FCC opened up wireless spectrum bands in 1985, Wi-Fi has kept evolving. The availability of low cost unlicensed Carrier-grade spectrum and its widespread use make Wi-Fi the technology of choice for offloading cellular networks at the dawn of “The Internet of Things”. The fact that Wi-Fi is a well-known mature technology, that it is easy to deploy and does not interfere with cellular networks further secure its lead.

Did you know that it took 25 years to transition from DSn/PDH to SONET/SDH (1962 -1987), 14 years to transition from 2.5G to 40G (1990 – 2004), but only 5 years for 100G to go from definition to mass deployment (2009 – 2014)? High Speed is happening faster than any other rate deployment. Here is an infographics that illustrates how quickly networks are evolving and some tips on how to get ready for what will happen next.

One of my areas of interest is mobile technologies and services. As you know, the mobile network is experiencing a paradigm shift: instead of delivering services via a wide Radio Access Network (RAN), operators and the general mobile industry is now looking at another approach: densification.

Cable-Tec Expo is just around the corner and I am happy to announce that one of my papers has been selected to be presented at the event on September 22. The paper, entitled Optical spectral planning for 40G/100G deployments: tradeoffs and their impacts, covers the definition of coherent vs non-coherent, as well as greenfield vs brownfield and their respective tradeoffs in terms of bandwidth, scalability, and impact on the quality of service. It also explores some avenues for network upgrade for greenfield and brownfield next-generation technologies.
