5G commercial rollouts are in full swing. By the end of May 2020, a total of 81 operators in 42 countries had launched one or more 3GPP-compliant services, according to the Global Mobile Suppliers Association (GSA). But the early commercial deployments have not yet had a big impact on transport network architectures. With the recent
The ROADM Tutorial Blogs, part 4 In this series of tutorials I explain the key functionality (and their benefits) that underpin next-generation ROADM: Colorless, Directionless, Contentionless, and Gridless (CDC-G) functionality. In this blog, I explain the second “C” – Contentionless – and the operational benefits it provides. Previous ROADMs were Contentionless First, let’s define contentionless.
In Part 1 of this blog series, we explored the many benefits network operators will reap from Open RAN (Radio Access Network) architecture. Opening up the interfaces between the Radio Unit (RU) and Baseband Unit (BBU) allows these operators access to a wider range of hardware and software choices to prevent vendor lock-in. Open RAN

My previous blog discussed the advantage of increasing the baud rate of a wavelength in order to increase transport capacity without sacrificing reachable distance. One drawback of this approach is the fact that the spectral width of the wavelength increases from 50 GHz to either 75 GHz, 100 GHz or even 150 GHz depending on the selected baud rate.
Open RAN (Radio Access Network), or O-RAN, stands at the forefront of the RAN revolution and is the latest of several generations of RAN technology that have evolved since the beginning of the cellular network. O-RAN aims to bring agility and the benefits of “cloudification” to the RAN. This blog, the first of a series on O-RAN, provides a high-level introduction to O-RAN and its benefits.
As the COVID-19 pandemic cut its destructive path across the globe, it left no area of our lives and livelihoods untouched. From seemingly trivial everyday details to macro-scale policies, everyone is affected by its consequences: not just from the risk of infection itself, but from the restrictions imposed by prevention. Social distancing and a widespread
As demand for bandwidth continues to explode and connectivity becomes more critical than ever, communications service providers (CSPs) often face multiple challenges in operating and maintaining the underlying network infrastructure that typically spans multiple business entities across network domains. In order to offer services to customers with geographically diverse locations, CSPs often lease resources in
How to Master Multi-vendor Optical Network Orchestration and Automation in Hybrid Legacy / Next-Gen Networks
In the age of cloud-native transition and SDN, communication service providers are facing many challenges, including how to maximize their existing legacy infrastructure investments. This challenge is most visible at the optical layer (Layers 0 and 1), as optical devices have long refresh cycles. To remain competitive, providers must upgrade to next-generation architectures that can support new use cases and enable complete automation.
Every day, we learn more about the reasons behind America’s growing digital divide. A major cause is that the needed investment to close the gap has not happened. As a result, a growing number of rural electric co-ops and municipal utilities are stepping in to provide the high-speed internet needed to spark community growth and bolster flat or declining electric revenues. As the Practice Leader of Fujitsu’s rural broadband team, I’m proud to be part of this effort.
Even as networks struggle to adapt to changing customer patterns and surging demands for bandwidth, telecommunication providers must continue to provide reliable, cost-efficient services. This means delivering more dynamic capacity and reach at the lowest cost per bit. In today’s high-speed optical networks, two key variables affecting capacity and cost are baud rate and modulation density; both can be managed and optimized.
Service providers are rapidly transforming their networks to deliver competitive and affordable 5G services, and cell site densification is one of the key factors in the eventual success of 5G. But deploying fiber and then maximizing bandwidth capacity to so many cell sites can be an expensive proposition. Compared to active WDM-based offerings, Ethernet-based mobile
So you’ve read the research about the benefits of broadband—for the community, your business and electric customers. You’ve sat through town council meetings or board of director meetings, listening to residents and business owners lament the spotty service and slow connect speeds of the current service providers. Now you’re thinking about taking matters into your
User experience (UX) design is a widely accepted role in the consumer software development lifecycle, and, in many cases, has proven to be the key differentiator in winning business. Yet enterprise UX designers still struggle to justify the significance of UX design in the overall development process. Today, misconceptions around UX design lie in the
The telecoms industry is experiencing a major transformation as we usher in a new year, offering promise and opportunity to communication service providers (CSPs) worldwide. But this shift certainly didn’t happen overnight. A number of trends have steadily advanced on the horizon, while the industry has watched and waited for tomorrow’s technologies to reach full

Widespread access to broadband is changing the way we live, work and design our cities. But not every community is benefiting from this sweeping change. This is especially true across rural America, where the digital divide threatens to leave many smaller communities behind. For these communities and the rural electric co-ops that serve them, access
