With the evolution of the technologies deployed in the field over past years (e.g., Remote-PHY, 5G, C-RAN, Remote-OLT, 10G to the business), distribution networks are being put under a lot of stress. To increase the efficiency and the density of data, wavelength division multiplexing (WDM) has always been the most optimal solution. It started with CWDM and 18 channels, but now DWDM is more common in the industry. The 100 GHz version that is deployed provides the capability of 44 channels of 10 Gbit/s (25/50 Gbit/s soon). In some cases, this is over a terabit travelling per second through one fiber strand in the distribution/access network. Under such circumstances, we cannot simply plug and pray, hoping for the best. We need to make sure that every connector, splice, MUX, DEMUX are tested using the appropriate wavelengths and correct colored transceiver TX is received at the proper level on the RX side. When a DWDM is half full it is hard to troubleshoot with legacy test equipment and obviously we cannot disconnect other customers to troubleshoot one service. This is why inline DWDM OTDR/iOLM channel testing is required. In this educational webinar, we will explore the challenges inline DWDM channel testing. We will examine a testing solution that leverages best practices for optimal results. Key takeaways: Knowing the challenges of deploying DWDM technology in distribution/access/FTTN Understanding the testing capabilities required Seeing a test solution at work (namely the Optical Wave Expert)

Video represents a critical opportunity for many operators. More than half of them now associate revenue with OTT video, or plan to do so within the next year. And why not? Video makes up 65% of today’s network traffic, and will exceed 90% in 5G networks by 2024. But failing to deliver a good video Quality-of-Experience could be costly. Operators know that poor video QoE is the leading driver of network-related churn. The trouble is, fixing quality issues is still a stubbornly difficult task, especially since half of the problems originate outside of operator networks and thus are out of their control. With the COVID-19 pandemic accelerating the use of video, flawless video experiences have become a baseline expectation, especially as 5G comes online. Failure to properly manage QoE will impact operators’ ability to capitalize on the opportunity that video presents. In this webinar, Light Reading’s Alan Breznick will discuss these issues in depth with Gorkem Yigit, lead analyst for the Cloud Infrastructure Strategies and Media Platforms at research firm Analysys Mason, and Ken Gold, Director of Test, Monitoring and Analytics Solutions at EXFO.

The concept of internetworking could not exist without the Transmission Control Protocol (TCP) standard. Sharing files, sending emails, browsing the Internet are all based on TCP. In addition, TCP is used for organizing and transferring large amounts of data in a way that ensures secure and reliable communication between severs and connected devices (i.e., end users). The most widely used Ethernet tests for validating network performance for E2E services are RFC 2544 and EtherSAM, with EtherSAM being the go-to test for validating service level agreements (SLAs). Today, as more people are transitioning to a teleworking environment, they depend even more on their home internet service in order to do their jobs. Given this new reality, the TCP process becomes critical for validating network performance and SLAs. During this webinar, we will explain the TCP test process, how it works, and how to efficiently troubleshoot an end-to-end service using TCP. Key takeaways: What is TCP What are the different TCP tests available How to troubleshoot a service

FTTH, FWA, 5G… As technologies converge in the field, the race to fibre densification has started with its rules: service providers have to accelerate rollouts to monetise the fastest while contractors must meet ROI by delivering on time without compromising on quality. To win the fiber race while ensuring a rock-solid network foundation, everyone is asking the following questions. How to get more jobs done? What visibility can I get? How to minimise truck rolls? What to invest in? This webinar will take on these questions and challenge current testing approaches, exposing their impact on both pace and quality of massive fibre deployments. Doing the job right the first time has never been so critical, and we will see how a simple proactive approach can become the make-or-break factor. Key takeaways: Fibre densification challenges during deployment, operations and maintenance (O&M) Accelerating rollouts without incurring costs or compromising quality Opportunities emerging in O&M Achieving ROI through leaner methods of procedures

In order to successfully deliver 5G services, service providers must ensure proper radio frequency (RF) signal quality throughout their networks. To maintain high RF-signal quality, interference-causing sources on the 4G network must be quickly and easily identified. But why is 5G so heavily dependent on 4G network architecture in the first place? And how can RF-signal problems be easily found and solved? Join us for this training workshop where we’ll discuss the relationship between 4G and 5G networks as well as provide an overview of EXFO’s Intelligent OpticalRF (iORF). An intelligent solution for RF spectrum analysis over CPRI, iORF enables operators to remove the complexity from RF interference and PIM analysis, putting the power back in the hands of field technicians, regardless of the depth of their experience–and enabling mobile network operators to save time and money in diagnosing RF interference issues.

Each home, school or business has different requirements when it comes to upstream and downstream broadband speeds over fiber—from basic to ultra-fast. To deliver the right speed to the right customer, service providers are deploying both next-generation (XG/XGS-PON, 10G-EPON and NG-PON2) and legacy (GPON/EPON) passive optical local area networks (PONs) by overlaying multiple new wavelengths on existing fibers. This poses a new challenge for field technicians as each stage of the network lifecycle—deployment, activation and troubleshooting—may require different test tools and techniques. This webinar examines the latest trends in PON technologies and the best practices in testing and troubleshooting them efficiently. Key takeaways: Legacy and next-gen PON networks: the new challenges How to make sure your MoPs meet deployment requirements New troubleshooting techniques Best practices to ensure first-time-right deployments

The notion of automation in CSP operations is not new. Over the past 20 years, we have seen a steady progression of applications and processes leveraging automation—everything from batch processing to workflow automation. What began as simple scripting exercises, driven internally by a major Tier 1 CSP, has developed into a billion-dollar industry, striving toward the goal of ‘zero-touch’ operations. And today, the stakes couldn’t be higher. The intersection of virtual and cloud networks, with the emergence of 5G and massive IoT, have created a perfect storm. CSP operations teams have been forced to completely rethink their processes and embrace automation in order to survive the complexity of this new world order. Join us as we discuss the challenges facing today’s telco operations and highlight some unique examples of how automation is helping overcome them.

Has 5G made mobile radio access a hot topic of discussion again? Perhaps. Is the radio access network (RAN) attracting more attention because of architectural changes, especially those required by network virtualization/cloudification and the move to open (non-monolithic) architectures? Maybe. Whichever the case, mobile RAN has been evolving for a number of years, gradually taking a multifaceted new—effectively “hybrid”—form (including but not limited to “physical” and “virtual” or “cloud” RAN). This has also impacted RAN-related challenges. In fact, many challenges are similar to those encountered in the past (e.g., spectrum availability). Some have become more complex (e.g., RAN optimization). Some are due to the different nature of supported use cases. And there are also new (e.g., fiber and cloud network infrastructure) challenges following the RAN disaggregation and the adoption of IT concepts. So, if we consider all challenges—and benefits—together, are we now better or worse off with the new RAN? Key takeaways: What the new RAN looks like, and what its description as “hybrid” means What the main benefits and key challenges are for the new (hybrid) RAN What major network operators have been doing to address these key challenges Our webinar is based on mobile industry experience and engagements with leading network operators worldwide. Join us for a lively discussion, ask questions in the Q&A session and decide if the new (hybrid) RAN is a “beauty” or a “beast”!

The 5G network architecture requires slicing to efficiently deliver various services within a single network. Each slice will use some of the network’s shared resources to deliver a specific service with a specific service-level agreement (SLA) to specific devices. Different slices will be required for low latency, maximum throughput and massive IOT services, just to name a few. In addition, FlexE (flexible Ethernet) can be implemented to achieve low latency slicing and assign the necessary dynamic bandwidth required for certain applications like live sporting events. The FlexE technology will adjust service bandwidth based on data usage and speed requirements without over-provisioning the network. FlexE bandwidth connectivity can be scaled up or down, as per service requirements. In this webinar, we will cover 5G network slicing concepts, the basics of FlexE technology and how you can monetize your 5G network, slice by slice. Key takeaways: Overview of network slicing Understanding FlexE technology Role of FlexE in efficient network slicing
