There are any number of things you can point to that demonstrate what is driving growth in fiber deployment, regional FTTH/PON initiatives, national high-speed broadband growth, core network 100/400G upgrades, or preparation for new services such as 5G. One thing that is critical for these new or upgraded services to function to their peak and […]
In anticipation of growth in the 3D imaging and sensing market, and to further enhance support of our Optical Security and Performance Products customers, VIAVI has completed construction of a new manufacturing plant and cleanroom facility in Henrietta, New York. The new plant replaces a facility formerly operated by RPC Photonics, which VIAVI acquired in […]
This morning, VIAVI introduced two new assurance solutions – including a patented 3D geolocation feature – that give operators a view of 5G coverage and subscriber experience, allowing them to transform 5G planning and performance engineering. Combined, they deliver comprehensive visibility that allows them to attract new vertical markets and drive new revenue streams. This release […]
When faced with validating and resolving a performance problem with a complex application, we need complete visibility into how the various components of the application are performing. The way most vendors approach this need is to deliver Key Performance Indicators (KPIs) that describe how each of the various elements of the system is performing. Having […]
With the move to pluggable coherent optical modules for the first time since 10G, we see client and line side considerations coming together. The most obvious example of this is optical signal to noise (OSNR) and related measurements. For any modules with the potential for use in an amplified system, OSNR becomes the fundamental figure […]
I recently participated in an interesting online debate about the use of wireless technologies to track pandemics, as part of the Senza Fili #WirelessFightsCOVID webinar series. During our discussion, there were a lot of opinions on how to track the spread of infection and what is the best and most secure way to do contact tracing […]
Make The Connection – How Your HFC Tools Can Work Harder For You The people who monitor and maintain HFC networks have an impressive if not overwhelming number of tools available to them today. Some of these tools like upstream spectrum analyzers and plant leakage systems have been around since the early days of […]
With the advent of 400G Ethernet, it has become critically important to fully understand and validate Forward Error Correction (FEC) logic and the related software and firmware. 400G Ethernet uses PAM-4 signalling optically and electrically. Because of the susceptibility to the impact of noise, distortion, and other disturbances, most links will run with a raw error […]
Growing up in Castleisland, County Kerry, my family was lucky to know the famous journalist Con Houlihan. With his fantastic command of the written word he was often asked to advise on the progress of young student’s written English by concerned mothers. Con’s stock reply would normally be ‘Well, they are making all the right […]
One title that is in no danger of appearing on a list of “Most Boring Jobs” is that of Enterprise IT Director (or its equivalent). In the 2010s, IT teams had to contend with increasing adoption of advanced network technologies such as hybrid cloud or SDN. They became more and more involved with security investigations, […]
