DOCSIS

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 […]

The wireless ecosystem is a rapidly moving marketplace, and the next milestone is the large-scale deployment of small cells to augment network capacities and to support 5G deployments. There are three main elements required to deploy small cells: Location Power Backhaul These requirements put cable operators, many of whom are also mobile operators, in an […]

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 […]

Just over two years ago, CableLabs announced the release of a new series of specifications known as “Remote PHY” in the blog “CableLabs® New Remote PHY Specifications expand DOCSIS® Network Deployment Options” authored by CableLabs principal architect Karthik Sundaresan. The blog describes what Remote PHY (R-PHY) is, how it forms a key piece of 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 […]

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 […]

Open source software continues to make solid inroads in the world of network technology. There are various open source industry efforts which are becoming de-facto standards that are being adopted by operators and equipment manufacturers (Linux, Apache, OpenStack, Docker etc). Open source leads to free and quick proliferation of good ideas. Collaboration tackles tough problems […]

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 […]
