In the past, I was forced to limit the size of my mail folder. Now those days are gone. The relative costs of storage versus manual deleting have changed. Today it’s cheaper to keep information rather than spend the time deleting it and occasionally experiencing issues with lost data. What’s more, it’s now easy to rapidly expand storage and compute capacity by allocating it to resources in the cloud on demand and in real time. All you need is a fast and secure connection to the data center ...

It’s been a busy few months for our FSP 3000 TeraFlex™. Following a series of 600Gbit/s trials showing how the solution addresses the growing bandwidth needs of metro DCI networks, TeraFlex succeeded in a unique ultra-long-haul demo. 300Gbit/s of data was transported over a 6,800km fiber link representative of a cost-optimized submarine cable ...

“The future of 5G remains hazy but certainly promising.” This might have been both the best and most concerning quote I heard at the 2019 IEEE Brooklyn 5G Summit – especially coming for the CTO of a Tier 1 US operator. In other words: We have this really cool technology that has a lot of potential. We think there are some really good use cases, but we aren’t exactly sure which ones will take priority beyond mobile broadband. However, we think it could be impactful to the industry, particularly the enterprise for industrial automation. Okay. Hazy for sure ...

It’s no surprise to see disaggregated optical networks being widely adopted by data center providers.  It’s an approach that fulfils their needs perfectly. Disaggregation triggers innovation, increases flexibility to mix and match best-of-breed networking components, avoids implementation lock-in and integrates into open source and commercial orchestration. What’s more, it accommodates the different lifecycles of various networking components. Line terminals, for example, usually follow a much shorter innovation cycle than optical line systems ...

Keeping mobile networks on track is no easy task as they evolve from 2G to 3G to LTE and finally 5G. Each mobile radio innovation comes with additional requirements for the underlying transport network, resulting in new interface cards or replacement of transport network devices. This constant change creates pain for the network design teams and service teams, not to mention significant cost. A new approach for transport network evolution is overdue ...
