Frequency bands over wireless networks are getting overcrowded, and space is not unlimited. And as the number and type of devices coming online increases, the number of interference-causing sources also increases. This can lead to reduced coverage, capacity and throughput—all of which can have a major impact on the quality of service (QoS) and quality of experience (QoE) for the end user. With so many 4G/LTE and 5G cell sites being deployed, cell technicians and contractors will need smarter RF test tools and processes to help them do more, faster and with first-time- right results. As well, being able to quickly diagnose the root cause of RF interference issues will be key for helping operators drive down costs, improve network quality and maximize ROI on their RF investment. In this case study webinar, we will discuss how frontline technicians were able to detect, identify and locate RF interference issues at a 5G non-standalone site—consequently, improving site KPIs and generating significant cost savings quickly and easily. Key topics for discussion: how did RF interference affect the operator’s 5G network? how did radio frequency (RF) spectrum analysis over CPRI help determine the root cause of the issue? RF over-the-air spectrum analysis: which best practices were used to help locate interference sources?

New way to verify 5G fronthaul OSP fiber networks This webinar details a new, comprehensive approach to validating 5G fronthaul outside plant (OSP) optical networks. The webinar is structured in three parts, each lasting around 10 minutes. Part 1: Technology overview and evolution of 5G fronthaul network The introduction will provide a technical overview of technologies presently deployed and a glimpse into upcoming trends and their impact on the fronthaul architecture. Part 2: Construction and activation using portable test equipment Review of real-life examples and field results to explain what should be done during construction, installation, and activation phases of the fronthaul fiber-optic network to guarantee optimal quality and stability of 5G services. Part 3: Burn-in and monitoring of fronthaul fiber This part explores centralized fiber monitoring which helps to capture degradations of the optical fiber over time and correlates issues with environmental conditions. Distinguishing whether the detected problem is at the physical layer or at an upper layer is key to sending the right person at the right time to the right place. The webinar will show the need for centralized fiber monitoring as an inherent part of the 5G deployment structure through real-life examples and scenarios. Key takeaways: Evolution from CPRI to 25G eCPRI and from RAN to C/D-RAN to O-RAN Construction and activation portable test solutions (optical multimeters, OTDR/iOLM and fiber inspection) Centralized fiber monitoring solutions (OTDR-based remote test units, Grafana and API-based integrations)

Please note, this webinar will be presented in German. FTTx rollouts are in full swing in Europe’s German-speaking countries. The number of FTTH connections has ramped up hugely in the last 2 years. However, due to the shortage of skilled workers, there is also a growing awareness of the need to boost the efficiency of network installations by accelerating rollouts while simultaneously minimizing costs.   This webinar explores three novel approaches to achieve cost-effective efficiency: Centralized testing leveraging OTDR technology for a more managed, yet largely autonomous, automated deployment and continuous 24/7 monitoring.   Automation of on-site acceptance measurement. Acceleration of network availability through the validation of network construction progress and quality in real time with the aim of earlier commissioning. All in all, this leads to just-in-time billing.  Optical fiber multimeter at work during FTTx installation. This equips technicians in the final construction phase with a simple, fast analysis method to increase quality while avoiding repeat truck rolls or escalating promptly to second-level technicians in the event of a fault.

Some say the pandemic hindered 5G progress; some say it accelerated its rollout. More than two years into COVID-19 where does 5G stand globally? This webinar explores how different regulations, spectrum availability and customer demands impact the deployment and adoption of next-generation cellular services around the world.

Please note, this webinar will be presented in German. Each home, school, business or other type of customer has different requirements when it comes to upstream and downstream broadband speeds delivered over fiber—from basic to ultra-fast. To deliver the right speed to the right customer, service providers are deploying both next-generation (XG-PON, XGS-PON, 10G-EPON and NG-PON2) and legacy (GPON, EPON) passive optical local area networks (LAN) or POLs by overlaying multiple new wavelengths on existing fibers. This becomes challenging for field technicians, because for each stage of the network lifecycle—deployment, activation and troubleshooting—the correct tools and techniques can be different. This session examines the latest trends in PON technologies and techniques for deploying and maintaining these fiber optic networks as efficiently as possible. This session will cover: legacy and next-gen PON networks and the challenges they pose how to make sure your methods and procedures meet deployment requirements new quick and efficient troubleshooting techniques best practices to ensure first-time-right deployments

5G fronthaul mandates higher data bandwidth than 4G access networks, which invariably requires the use of additional fiber optic links to support these higher throughputs. In addition to more fiber links, existing fiber infrastructure must also be leveraged as a critical path to 5G. As such, aging fiber networks need to support a mix of optical technologies, such as PON and DWDM. Meanwhile, networks are becoming denser to accommodate increasing cellular traffic and provide the improved coverage that 5G demands. These are some of the factors contributing to the vast number of small cell deployments—which in turn will require lots more fiber in more places. In this webinar, we will present strategies for accelerating 5G fiber rollouts, including how to ensure existing fiber will support 5G to deliver top-notch quality of service (QoS), all while maximizing ROI. Key topics include: Retrospective: challenges of early 5G rollouts Fiber testing strategies to ensure high quality of service Best practices for accelerating future 5G fiber rollouts

Technologies like 5G and cloud services have fueled a tremendous increase in bandwidth demand. Installation of high-count fiber and an increase in bandwidth to 100G+ have helped meet some requirements, but to fully meet unsatisfied demand, advanced technologies like dense wavelength division multiplexing (DWDM) must be deployed. DWDM has long been a technology used on backbone transport but it’s now pushing out into the metro environment to feed bandwidth-hungry services. Front line technicians and contractors who install, maintain, and troubleshoot metro services today will need to prepare for advanced technologies like DWDM. This 45-minute webinar will cover the following topics: introduction to DWDM (5 minutes) architecture and components of a DWDM network (10 minutes) passive vs active xWDM testing (5 minutes) qualifying and maintaining a healthy network (20 minutes) understanding OSNR and how it impacts your network (5 minutes)

Die Arbeit mit vorgegebenen Grenzwerten hilft Technikern zu entscheiden, ob eine gebaute Glasfaserstrecke gut oder schlecht ist. Schwellenwerte helfen dabei, die geleistete Arbeit zu bewerten, und die Einhaltung der Grenwerte ist ein entscheidender Faktor dafür, ob Auftragnehmer für ihre Arbeit bezahlt werden oder nicht. Welches sind zum Beispiel die geeigneten Schwellenwerte für einen Spleiß? Und können Schwellenwerte zu strikt sein? Der jüngste Trend geht in Richtung strengerer Grenzwerte, was zu zusätzlichen und manchmal unnötigen Arbeiten und Tests führt. In diesem Webinar werden die verschiedenen von den Normungsgremien empfohlenen Grenzwerte für die Tests von Glasfasernetzen und deren Anwendung untersucht. Wir werden auch Empfehlungen für sinnvolle Schwellwerte geben - solche, die zu einem qualitativ hochwertigen Netzwerk führen, ohne zusätzliche Arbeit für Techniker zu verursachen. Die Teilnehmer erhalten weiterhin Informationen darüber, wann Schwellenwerte angefochten werden können, welche Schwellenwerte als unangemessen gelten und wie sichergestellt werden kann, dass die richtigen Grenzwerte immer zum richtigen Zeitpunkt festgelegt werden. Wichtigste Erkenntnisse: Empfohlene Grenzwerte für Messungen an Glasfaserkabeln Problemloses Arbeiten mit Grenzwerte für das Testen eines Glasfasernetzes. Ein alternativer qualitativer Ansatz zur Bewertung von Glasfaserstrecke und wie effizient und robust diese aufgebaut ist Begleiten Sie Christian Till dabei, wie er Fakten von Gefühlen trennt, wenn es um die Verwendung der richtigen Schwellenwerte bei der Durchführung von Glasfasermessungen geht.
