Full-fiber broadband is already on the horizon. In fact, the APAC region are ahead of the curve as Singapore reaches first place with 93% fiber coverage across the island. The rest of the world is following along with substantial investments into similar infrastructure across multiple countries. For example, the UK recently approved a £5 billion […]
With the arrival of 5G already occurring in select countries and the anticipated launch expected to happen in most within 2020, the need for telecom engineers to be skilled and trained within all aspects of 5G is evident. In order to achieve set targets and for the roll-out of 5G to be deemed successful, telecom […]
Con Houlihan, the great Irish sports writer from my hometown of Castleisland, once replied to a young poet who had shared his writing, “Keep going. You’re making all the right mistakes.” As a young boy, the words did not fully resonate with me, but now—a bit older and hopefully wiser—I can see the wisdom therein […]
This is the fifth in a series of blog posts on the Evolution of Fronthaul, links to past posts below. Preparing for Massive MIMO and 5G As CPRI technology is increasingly being deployed in cell densification and CRAN projects, eCPRI is starting to receive the attention of the global wireless community. As I outlined in […]
This is a re-post of an article in Gazettabyte, © Roy Rubenstein 2017 The race is on to deliver 400-gigabit optical interfaces in time for the next-generation of data centre switches expected in late 2018. The industry largely agrees that a four-wavelength 400-gigabit optical interface is most desirable yet alternative designs are also being developed. Optical […]
Part 2 of the Evolution of Fronthaul Networks (read Part 1: Intro to Fronthaul and Part 3: CPRI ) As we learned in part 1, fiber deployment permits the placement of RRH’s closer to the antenna. Also known as light radio, this RRH placement has significantly improved the energy efficiency of cellular networks as the […]
Fronthaul? Until few years it was unknown for most involved in network deployment. Smart phones, the explosive growth in use of media reach apps and the competitive pressure for operators to offer higher data limits have changed the role of fronthaul completely. One can hardly oversee the rising number of antennas and radios mounted on […]
At the end of March, Viavi attended the OFC 2017 conference in Los Angeles, California. It was a vibrant, busy show with a great international showing – both in the exhibitors and attendees. There are many new, exciting innovations and collaborations happening in the fiber optics arena and we are proud to be a part […]
The acid test of any emerging communications rate is a live field trial. The whole ecosystem must come together—from chips to systems, from lasers to complete optical links—before a single bit of large traffic can be sent. It’s where the rubber meets the road. Furthermore, large carriers like AT&T need technology to be robust and […]
In this Olympic year, the motto Citius, Altius, Fortius (Latin for Faster, Higher, Stronger) seems very relevant to where we are with Ethernet networking. We need faster bandwidth, higher levels of service and stronger performance to push around all those videos of cats—as well as the more serious (and less cute) business traffic. Approximately every […]
