Over the past few months, teams have been very busy developing 400G class pluggable optical modules. Both as QSFP-DD, predominantly for -ZR 80km applications, and CFP2 for full multi-service DWDM. These coherent modules are a complex mix of photonics, high speed electronics, DSP and firmware as well as mechanical and thermal engineering and we at […]
Here’s a situation that you may find recognizable. There is a critical service delivery issue and IT leadership pulls together a tiger team of 8-10 people into a war room session — several network engineers, a few developers, some security analysts, and the CTO are included. Within the first 20 minutes, the network engineering team […]
Timing and synchronization is everything in 5G For a mobile network operator, timing is everything. Not just determining when to upgrade the network to bring new services to market, but in the literal sense as well. If the radio clock loses synchronization accuracy in a radio access network (RAN), or the radios are out of […]
At the moment, China currently sits at the top of the world standings when it comes to the number of 5G towers successfully installed. However, even with 600,000 5G towers and base stations installed throughout the country, it has only touched the surface of complete 5G penetration, as the country will need up to 10 […]
Advanced Upstream Blog Series Introduction In the Advanced Upstream blog series we will explore how cable operators have traditionally managed upstream bandwidth capacity planning, how market dynamics and technical innovation are driving changes, and where things are likely headed in the coming years. In this entry we will discuss the “more Nodes” approach – how […]
In an increasingly digital world where every pillar of information is now online, lightning-fast connectivity, rock-solid reliability, and impenetrable security are transforming into essentials within the network industry. 5G transforms the connected ecosystem and pushes the boundaries of connectivity to lay the foundation of a faster, more secure, and sustainable future. For years, if […]
Viavi Solutions Inc. (VIAVI) will showcase this week a range of products engineered to simplify and accelerate high-speed network test across all phases of the network lifecycle including development and system verification, manufacturing, turn up and installation, and troubleshooting and monitoring. The new products highlight the VIAVI presence at OFC 2021, taking place virtually from June […]
RAN Intelligent Controller At the O-RAN Alliance Plugfest at the end of last year, VIAVI, alongside partners AT&T, Samsung and Nokia, demonstrated an end-to-end traffic steering use case based on a number of open source components. One of these was the near real-time RAN Intelligent Controller platform, or RIC. Central to the demo was VIAVI’s […]
Understanding RAN The RAN (Radio Access Network) architecture for mobile networks includes a remote radio unit (RRU) located at the top of a cell tower, which communicates with a baseband unit (BBU) at the base of the tower. The hardware and communication interfaces are owned by a specific vendor, and its software-driven functionality is tightly […]
Benchmarking O-RAN performance O-RAN was big news last year, and a recent announcement from the O-RAN Alliance – one of the main bodies encouraging open RAN innovation, highlights the importance of benchmarking and testing in helping operators and others develop and get value from Open RAN deployments. Recently, the O-RAN Alliance launched a Minimal Viable […]
