Cable Network Reliability: ProOps Platform for PNM and More!

July 23, 2019

Cable network reliability has many important dimensions, but operators are all too familiar with the significant cost of maintenance and repair, and some with the advantages of Proactive Network Maintenance (PNM). But not everyone has taken full advantage of PNM. Let’s have a look at some of the reasons for that, and what CableLabs is […]

OFC: A Third of a Mile of Next-Gen Optics

April 23, 2019

0.0000026 seconds. For the more technically inclined, that’s 2.6 microseconds. Which is how long it would take light to travel a third of a mile through fiber optic cable. It was also the length of the show floor at OFC: The Optical Networking and Communications Conference and Exhibition, held in March in San Diego, California. […]

Proactive Network Maintenance (PNM): Cable Modem Validation Application(s)

April 10, 2019

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): A Primer on the Essential Element for Optical Transmission Interoperability

April 4, 2019

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 […]

The P2P Coherent Optics Specification of the Future, Available Today

March 12, 2019

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 […]

Proactive Network Maintenance (PNM): Are You InGeNeOS?

February 19, 2019

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 […]

Proactive Network Maintenance: Where Is Common Data Collection Going Next?

January 22, 2019

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 […]

The Profile Management Application: Optimizing DOCSIS® 3.1 Networks

January 14, 2019

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 […]
