Modern high-speed links for the fastest Ethernet rates of 400GbE and above use PAM-4 electrical modulation. This modulation format allows interfaces to run at the speeds required for 400GbE and above, but PAM-4 modulation is more susceptible to the impacts of noise and signal integrity. This is mitigated by the use of forward error correction […]
The story of artificial intelligence, or AI, is one that spans decades and multiple industries. AI enables a myriad of potential applications that will transform the way we live and work. In the telecommunications industry, we are already seeing AI’s impact and a future where AI enables the automation, orchestration and optimization of networks and […]
New risks are on the rise for telecom networks, Having the right security solution in place as early in the development phase as possible is required. The proactive security strategies should include a focus on the role of DevSecOps, Zero Trust, and AI/ML to address the fast-approaching challenges of the near future. Telco networks are […]
In today’s fast-paced digital landscape, high-speed connectivity is not just a luxury; it’s a necessity. With the increasing demand for faster and more reliable network services, service providers and fiber infrastructure providers are increasingly turning to remote fiber test systems (RFTS) to guarantee fiber infrastructure availability, reduce fiber network outages, and improve service delivery. These […]
In today’s data-driven world, the transfer and protection of sensitive information is paramount. Companies, financial institutions, governments, and individuals rely heavily on secure data communication to maintain confidentiality, personal information, banking information, and to safeguard intellectual property. Data transits around the world through a very complex network of interconnected infrastructure. Most of the the world’s […]
As we know, fiber optic cables are now the backbone of modern communication networks, offering unmatched bandwidth and reliability. But just like any other technology these cables are susceptible to degradation over time. As cables age, network owners and operators encounter several challenges that can impact the overall health and performance of their networks. One […]
Network security architectures are changing. We’ll examine an emerging new architecture called Zero Trust Network Access and how it helps ensure data safety and integrity and enables the transformation from a static, data-centric approach to a more dynamic, policy-based one. You’ll learn about the benefits of the Zero Trust approach and related validation solutions. Typical […]

Written Testimony Dr. Sameh Yamany, […]
Passive optical networks (PON) have revolutionized high-speed internet connectivity by providing efficient fiber-based broadband services. To ensure the quality and performance of these networks, a robust certification process is essential. In this blog, we will explore a new centralized test approach to certifying the construction of passive optical networks and look at the kinds of […]
In the fast-paced world of telecommunications, the transition from 4G to 5G has brought about a host of changes, with both persistent challenges and emerging issues. In this blog post, we discuss the complexities of interference in 5G networks, exploring a combination of old and new problems that network operators and technicians face. Old Problems, […]
