Network convergence might sound like an enigmatic concept when, in fact, it’s simply the aggregation of all electronic mediums of communication onto one ubiquitous 5G network. In essence, it merges mobile, video transmission, data communication services into a coexisting network. The need for increased bandwidth in an always-online society is the motivation that has given […]
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 […]
Optical interconnectivity at 400 Gbps has introduced many new design challenges. These include the step from NRZ to PAM-4 coding with the presence of a background error rate, the new QSFP-DD form factor for transponders with thermal and integration challenges and aggressive cost expectations early in the lifecycle. One of the most difficult challenges is […]
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 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 […]
In just a few short weeks, the Viavi Solutions team heads to 5G World during TechXLR8 in London. Billed as the ONLY global 5G-focused, high-level conference and expo, the show addresses industry-impacting topics related to 5G trials and migration strategies from LTE to 5G. If you are going to the show, we invite you to […]
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 […]
