Full Duplex DOCSIS

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), […]

CableLabs is hosting a free Full Duplex (FDX) DOCSIS® technology (now DOCSIS 4.0 technology) seminar , April 17–18, 2018 that will be attended by both cable operators and DOCSIS suppliers. The seminar will take place at a private events center to provide attendees with a comfortable and professional setting to learn all about Full Duplex […]

Full Duplex (FDX) DOCSIS® (now a part of DOCSIS 4.0 technology) is an update to DOCSIS 3.1 specifications that builds on the core Orthogonal Frequency Division Multiplexing (OFDM) technology. This additional set of features significantly increases upstream capacity and allows for the same spectrum to be used as downstream or upstream. The set of MAC […]

Recently, in a significant step for the cable industry, we announced the successful completion of the Full Duplex DOCSIS® 3.1 specification (now a part of DOCSIS 4.0 technology). Today, we are pleased to announce the release of the DOCSIS® v3.1 Physical Layer Specification, which incorporates the addition of Full Duplex in Annex F per PHYv3.1-N-17.1771-6. […]

“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 […]

The demand for data network capacity has been growing exponentially year after year with no sign of stopping. If the past is a guide to the future, the cable industry must come up with radically more efficient use of the existing cable infrastructure in order to meet demand. Today, the most constrained part of the network, and the […]

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 […]

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 […]
