VIAVI Increases Capabilities for Industry-Leading Remote Fiber Test and Monitoring Portfolio

VIAVI | June 08, 2021

VIAVI Solutions Inc. announced the addition of many additional features to its award-winning Optical Network Monitoring Solutions (ONMS) family of remote test and monitoring solutions. The other capabilities provide even more network intelligence in fiber environments, which serve as the foundation for high-speed core, metro ring, and access applications in PON, 5G, and data center networks.

Due to wavelength and fiber density, optical network data rates are pushing new limits in transmission speeds through dense wavelength division multiplexing (DWDM), high fiber count cables, and complex point-to-multipoint and multi-fiber push-on (MPO) architectures. It is now more critical than ever for network equipment manufacturers (NEMs) and network operators to include remote network intelligence to provide excellent quality of service (QoS), near-zero downtime, and security. To do so, they must scale fibre network deployment, accelerate construction, increase service revenue, and manage an ever-increasing maintenance workload. Remote, automated intelligence enables the ability to climb high-quality standards and speeds without incurring additional expense or workload.

VIAVI responds with several new remote test and monitoring solutions that rely on rapid response and automation to manage dense, complicated networks:

• A patented new Flash Fiber Monitoring feature for ONMSi and SmartOTU software allows operators to detect and locate flash attenuation that causes network route flapping and burst network error conditions. The quality, which is an industry first, is 100 to 300 times quicker than regular monitoring, with performance capable of detecting flash attenuation in an unprecedented one-tenth of a second. One of the most common but damaging and difficult-to-diagnose problems is network route flapping. Until now, operators had no way of detecting or locating flash attenuation events, which cause millions of communication mistakes worldwide each year.

• New iOTDR Micro and Nano cards enable NEMs to integrate optical time-domain reflectometer (OTDR) technology into their elements at a low cost, with low power and a small footprint. The comprehensive software library for the cards provides operators with the most comprehensive variety of use cases in the industry via an element-integrated iOTDR solution, possibly saving NEM R&D teams 2–3 years of development time. The cards assist NEMs and their operators by providing an unparalleled range of applications such as fiber characterization, fiber monitoring, tapping security intrusion detection, fault demarcation, Raman amplified link test, and fiber degradation tracking for preventative maintenance.

• Using the NITRO BI Fiber Insight Platform for ONMSi, new fiber network analytics automate fiber diagnostics to proactively eliminate risks and establish a prioritized network performance improvement action plan. Fiber trends and aging use cases enable operators to view simplified reporting across the entire fiber network, allowing them to revise procedures. All fibers can be graded by cable, customer, network location, and fault type, transforming mountains of raw data into actionable insight.

In addition to the ONMSi remote fiber test system, VIAVI provides the industry's highest-performance OTDR technology, which generates an accurate, high-resolution trace to find faults, intrusions, and degradation in metro, core, access, and all-fiber networks. The OTU-8000 and OTU-5000 optical test heads from VIAVI work in tandem with ONMSi and NITRO software to allow users to optimize flexible OTDR capabilities, rack footprint, and price point. The system has applications for PON construction and service delivery, infrastructure monitoring, and network security.


VIAVI is a leading global provider of network test, monitoring, and assurance solutions for communications service providers, enterprises, network equipment manufacturers, government, and avionics. We assist these customers in controlling the network by using the power of instruments, automation, intelligence, and virtualization. VIAVI is also a pioneer in light management solutions for 3D sensing, counterfeit detection, consumer electronics, industrial, automotive, and defense applications.

Zenoss Launches Real-Time Kubernetes Monitoring

Zenoss | March 20, 2023

Zenoss Inc., the leader in AI-driven full-stack monitoring, today announced it has released streaming data monitoring for Kubernetes, the most widely deployed open-source orchestration platform used to manage containerized applications. This real-time monitoring of Kubernetes streaming data is part of a broader set of initiatives focused on cloud-based monitoring, which enables visibility for ephemeral systems that cannot be effectively monitored by traditional monitoring tools. Kubernetes was designed by Google in 2014 and donated to the Cloud Native Computing Foundation in 2015. It has become the de facto standard for running containers in production at scale, including in cloud environments such as AWS, Azure and Google Cloud. Also known as K8s, Kubernetes is supported by a community of professional programmers and coders from around the world. There have been over 2.8 million contributions to Kubernetes made by companies. Along with containers, Kubernetes has emerged as a primary technology for modern cloud-native workloads. According to the Cloud Native Computing Foundation, organizations using or evaluating Kubernetes increased from 78% in 2019 to 96% in 2022. Zenoss initially released monitoring and analytics for Kubernetes in 2018 and has delivered continuous innovation to become a leading monitoring platform for container-based environments. Zenoss provides full-stack monitoring and AIOps for public and private clouds, as well as for all on-prem IT infrastructure. The platform provides a view of containerized applications in the context of the broader infrastructure. This provides a common view for IT Operations, DevOps, DevSecOps, and business-level users. In addition to previously existing capabilities, Zenoss monitoring for Kubernetes now provides: Monitoring insights for Kubernetes clusters in a single pane of glass along with the broader infrastructure for K8s deployments in AWS, Azure and Google Cloud, as well as in private or hybrid clouds and locally hosted environments Secure, cloud-based monitoring with zero install Data collection and analytics in under five minutes Visibility into the health and performance of nodes, services, pods, containers, namespaces and more Intelligent dashboards with out-of-box templates Smart View, actions and notifications "There is a significant shortage of visibility into health and performance in these highly complex container orchestration environments," said Trent Fitz, chief product officer for Zenoss. “Just as application developers have adapted to be more efficient, scalable and automated, we are doing the same for monitoring these environments.” Zenoss Cloud is the leading AI-driven full-stack monitoring platform that streams all machine data, uniquely enabling the emergence of context for preventing service disruptions in complex, modern IT environments, including those built on Kubernetes. Zenoss Cloud leverages the most powerful machine learning and real-time analytics to give companies the ability to scale and adapt to the changing needs of their businesses. About Zenoss Zenoss works with the world's largest organizations to ensure their IT services and applications are always on. Delivering full-stack monitoring combined with AIOps, Zenoss uniquely collects all types of machine data, including metrics, dependency data, events, streaming data and logs, to build real-time IT service models that train machine learning algorithms to deliver robust AIOps analytics capabilities. This enables IT Ops and DevOps teams to optimize application performance, predict and eliminate outages, and reduce IT spend in modern hybrid IT environments. Zenoss is recognized in The Forrester Wave™: Intelligent AIOps Platforms, Q4 2022, the 2022 Gartner Market Guide for AIOps Platforms, and in the 2022 Gartner Market Guide for IT Infrastructure Monitoring Tools.
