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 […]

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 […]
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 […]
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 […]
In 2020, experts estimate that there are at least 31 billion IoT-connected devices worldwide. These devices rely on 5G connection to function properly and thus, perhaps now more than ever, there is a huge demand for 5G-ready telecom engineers and fiber contractors. In fact, research conducted by IHS Markit has predicted that by the year […]
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 […]
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 […]
A global pandemic, alien invasions, and the zombie apocalypse… it’s all fun and games when it’s just the theme of a movie. But when at least one of those movie themes starts to resemble real life, the impacts to business become all too real. Looking beyond this outbreak, cities, governments and nations will need new […]
