Sometimes, two apps are better than one. We now have two versions of the Cable Modem Validation Application (CMVA) available for download and use: a new lab automation version, and a data exploration version. Thing One and Thing Two Lab automation and certification have unique requirements, but investigation and invention require flexibility. Because the CMVA […]

Forward error correction (FEC) has been a powerful tool in the cable industry for many years. In fact, perhaps the single biggest performance improvement in the DOCSIS 3.1 specifications was achieved by changing the FEC being used in previous versions – Reed-Soloman (RS) – to a new coding scheme with improved performance: low-density parity check […]

Today, CableLabs is announcing another addition to our family of Point-to-Point Coherent Optics specifications:  The Physical Layer 2.0 (PHYv2.0) specification. This new specification defines interoperable point-to-point (P2P) coherent optics links running at 200 Gbps (200G) on a single wavelength. Just 9 months ago, in July of 2018, CableLabs announced the release of the P2P Coherent […]

Built on the successful completion of CableLabs’ DOCSIS 3.1 specification, Full Duplex (FDX) DOCSIS® technology (now a part of DOCSIS 4.0 technology) is a key component of the 10G platform that will significantly elevate the level of services available to consumers using existing cable broadband networks. With FDX DOCSIS technology (now a part of DOCSIS 4.0 technology), […]

I love a good acronym! InGeNeOS™ is an acronym built from Intelligent General Next Operations Systems. It’s the name of a CableLabs working group that solves Proactive Network Maintenance (PNM) issues for the cable industry, and it might be for you. What’s So InGeNeOS about PNM? The InGeNeOS group focuses on discussing, inventing, building and […]

Welcome to 2019, and the future of Proactive Network Maintenance (PNM)! As CableLabs’ PNM solutions mature, we look toward developing a framework for PNM that everybody can use. On December 21, 2018, CableLabs released the Combined Common Collection Framework (XCCF) version 2.0. This new version includes several enhancements, including refactoring to make it easier to […]

Cable operators are broadly deploying DOCSIS 3.1 technology around the world. Operators in North America and Europe have announced gigabit service offerings that use the technology across their footprint. In this blog, I focus on techniques by which operators can boost the capacity and robustness of their existing DOCSIS 3.1 network. Introducing Toolsets for Optimizing […]

On June 29th, CableLabs publicly unveiled for the first time two new specifications: P2P Coherent Optics Architecture Specification P2P Coherent Optics Physical Layer v1.0 Specification These two new specifications are the result of a focused effort by CableLabs, our members, and our manufacturer partners to develop Coherent Optics technology for the access network and bring […]

Over the past year, a quiet revolution in broadband services has been happening, thanks to investments cable operators are making around the globe: gigabit services are available to tens of millions households for the first time ever. Already, over half of households in North America can buy a 1 Gbps service from their cable operator, […]

An industry colleague recently reached out to a few of us with a problem: A cable operator was having trouble with a cable modem termination system (CMTS) in his network. The manufacturer of that CMTS had claimed that it was “DOCSIS® Compliant,” and therefore this operator apparently had assumed it would just work. We checked […]
