DOCSIS 3.1

In 1997, CableLabs released the very first version of Data Over Cable Service Interface Specification (DOCSIS ® technology) that enabled broadband internet service over Hybrid Fiber-Coaxial (HFC) networks.  Ever since, we’ve been making improvements, greatly enhancing network speed, capacity, latency, reliability and security with every new version. Today, cable operators use DOCSIS 3.1 technologies to […]

“In the United States, more than 90 percent of households are connected to an HFC (hybrid fiber-coaxial) network, and consumers typically have higher download speeds than upload speeds. By enabling Full Duplex DOCSIS (now a part of DOCSIS 4.0 technology), the upstream can flow up to 6 Gbps and downstream traffic can flow at up […]

During the CableLabs 2016 Winter Conference, CableLabs announced the Full Duplex DOCSIS (now a part of DOCSIS 4.0 technology) specification project that will significantly increase upstream speeds on the DOCSIS network. The announcement of the Full Duplex DOCSIS (now a part of DOCSIS 4.0 technology) extension of the DOCSIS 3.1 specification, and its potential of […]

The telecommunications industry typically uses Nielsen’s Law of Internet Bandwidth to represent historical broadband Internet speeds and to forecast future broadband Internet speeds. Mr. Nielsen predicted many years ago the high-end user’s downstream connection speed grows by approximately 50% compound annual growth rate (CAGR). In reality, actual peak service tiers offered by service providers over […]

CableLabs and Kyrio will be hosting a booth at the SCTE Cable-Tec Expo 2016.  To provide you with a sneak peek of what we plan to show at the event, below are highlights of six demonstrations: Full Duplex DOCSIS® 3.1 Technology With Full Duplex DOCSIS 3.1 technology, the HFC network can support 10 Gbps Downstream […]

At CableLabs, we are continually researching new methods of in-home wireless network distribution, and one exciting new contender is Li-Fi. What is Li-Fi? Li-Fi is the modulation of a free-space beam of light in order to transmit a signal. It can be thought of as analogous to Wi-Fi, just in a much higher frequency band […]

Building on state of the art technology, ongoing DOCSIS 3.1 technology deployments have squarely set the cable industry on the path to deliver Gigabit services over HFC networks. But there’s more to come! A newly unveiled project at CableLabs illustrates how DOCSIS 3.1 technology provides the basis for continued evolution of system capacities by supporting […]

For months, many people have been asking me: “When will DOCSIS 3.1 devices get certified?” My response has generally been something along the lines of: “When they successfully demonstrate they’re ready based on the test results. The team at CableLabs will do everything we can to facilitate this process, as our goal is to see […]

Around this time last year, CableLabs kicked off the first DOCSIS® 3.1 interoperability event. Looking back, it is amazing how far we have come. Over the last year, CableLabs has held seven DOCSIS 3.1 interoperability events that provide manufacturers with the opportunity to work together on interoperability, development, and compliance. A total of 27 vendors […]

Is the cable industry ready to deliver multi-gigabit broadband? Can the industry effectively compete in the market against fiber? Can the existing HFC plant scale to support the spectrum requirements of next generation services? The answer to all these questions is a resounding YES! as shown at CableLabs during a DOCSIS 3.1 demonstration day held […]
