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, […]
400G optics have already presented tremendous R&D challenges during the first phases of 400G QSFP-DD development. PAM-4 high speed signalling in both the optical and electrical domains, debugging module firmware and the interaction with the DSP firmware are clear examples, not to mention the new challenge brought about by the latest emerging standard in optical […]
VIAVI announced today that CRN®, a brand of The Channel Company, has named Carol Ann McKeown, Maribel Ortiz, and Katy Farney to its esteemed 2020 Women of the Channel list. Recognizing the unique strengths, vision, and achievements of a select group of women, this prestigious, annual list acknowledges channel leaders who are blazing a trail […]
Pluggable coherent optics are now being developed for 400G applications with two distinct streams emerging. One is high performance CFP2 based for 1000+km reach and multi-service applications and the other is QSFP-DD ZR (and perhaps OSFP) for DCI and metro Ethernet applications. Both streams present new challenges for test and measurement, not just to meet […]
3 challenges you might face with Open RAN deployment. The deployment and management of the radio access network (RAN) is the most expensive part of network. Today, new 5G radio access networks (RANs) are being developed to support a range of new features, including multiple-input, multiple-output (MIMO) antennas, large spectrum bandwidths and multi-band carrier aggregation. […]
The demand for fast, flawless network connectivity continues to expand across the globe as our world becomes increasingly digitally interconnected. High-speed 4G and 5G networks provide instant access to data-intensive apps, games and videos on billions of devices across the world, while the Internet of Things (IoT) allows them to seamlessly interact with one another. […]
In a data center environment, there are several key considerations that go into whether to deploy a multimode fiber, short-wavelength or a single mode-fiber-based, long-wavelength optical network. As they continue to drive critical business processes with fiber-optic connectivity as their backbone to allow connection with link servers, storage systems, and switches, both data centers and […]
A flu pandemic swept the world from 1918 to 1920, infecting approximately a quarter of the world’s population and killing over 50 million. One hundred years later, the world is again facing the reality of a viral pandemic. But today we have accumulated a century of health and technological advances that can fortify the fight […]
After the network has been turned inside out by an event such as an unexpected increase in remote working, an organization becomes more vulnerable to successful penetration. When faced with a potentially serious threat, it is obvious that we need to take the fewest steps and spend the least amount of time possible to efficiently […]
Every day, professionals across a range of industries rely on radio communications using Land Mobile Radio (LMR) technologies, including Project 25 (P25) radio systems. Whether a routine communication or a mission-critical emergency call, each transmission requires reliable and resilient technology. Radio test solutions play a critical role in ensuring that reliability and performance. Today, VIAVI […]
