10G

Cable service providers operate an extensive hybrid fiber coax (HFC) infrastructure to serve residential and business fixed broadband. In recent weeks, the world witnessed how cable networks around the globe have withstood the test of a dramatic surge in capacity demand due to the work-from-home (WFH) and other xFH practices induced by COVID-19 pandemic and […]

Those of you who’ve heard me speak on the topic of Point-to-Point (P2P) Coherent Optics have probably noticed that I’ve placed this technology in the context of the cable industry’s move to Distributed Access Architectures, and as a result, the dramatic change in the way networks are architected. It’s a change that I would argue […]

The future of connectivity holds technical enhancements that are meant to change the way we live, work, learn and play. A fully realized connected network that enables all the different use cases and provides ubiquitous coverage through a seamless experience will need to rely on multiple access technologies and choices. Seeing this paradigm shift in […]

As with most of my recent blog posts, I’m here to share some exciting updates on the work that CableLabs has been doing in the Telecom Infra Project (TIP) with virtualized RAN for non-ideal transport networks—for example, DOCSIS networks, passive optical networks (PONs) and really anything not on dedicated fiber. Over the past 6 months […]

In a continuing effort to meet the industry’s recently announced 10G goal, CableLabs is wrapping up the first major update to its DOCSIS specification since DOCSIS 3.1. DOCSIS 4.0 technology will enable the next generation of broadband over cable’s existing hybrid fiber coax (HFC) networks, delivering symmetrical multi-gigabit speeds while supporting high reliability, high security […]

If you’ve been following our blog and our recent 10G announcement, you know that one of the main areas of focus for us is latency. Achieving a near-zero latency on DOCSIS networks is one of the goals of the 10G initiative and is just as important as increasing speed or bandwidth. The success of future […]

As promised in the last couple blogs discussing DOCSIS based femtocells, we’ve saved the best for last. So far in the series, we’ve made the case for femtocells over DOCSIS networks and laid out the total cost of ownership (TCO) benefits of this deployment model. In this final blog post, I’ll share the results of […]

I am a GenXer, and I am addicted to my iPhone. But it’s not just me, today’s consumers, millennials and baby boomers and everyone in between, are increasingly spending more and more time on their mobile devices. Have you ever wondered what happens to your traffic when you interact with your iPhone or Android devices? […]

Remember the last time you waited (and waited) for a page to load?  Or when you “died” on a virtual battlefield because your connection couldn’t catch up with your heroic ambitions? Many internet users chalk those moments up to insufficient bandwidth, not realizing that latency is to blame. Bandwidth and latency are two very different […]

The 10g platform is going to provide reliable service. As the cable industry embarks on the development of 10G services, there is a lot of work ahead, but we already have a strong foundation of experience and technology to build upon. The 10 Gbps goal is about performance. But it must come with low cost, […]
