CableLabs Hosting a Free Full Duplex DOCSIS® Technology Seminar
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 DOCSIS technology (now DOCSIS 4.0 technology).
Scheduled speakers will be technologists who developed the FDX DOCSIS (now DOCSIS 4.0 technology) specifications, . Most have been involved with DOCSIS technology since the beginning, all are accomplished speakers who possess a wealth of knowledge to share not only about FDX DOCSIS (now DOCSIS 4.0 technology) but also about how the technology integrates into the family of DOCSIS generations.
FDX DOCSIS 3.1 technology (now DOCSIS 4.0 technology) allows cable operators to offer symmetric gigabit-speed data services over their existing Hybrid Fiber/Coax (HFC) networks, building on the core DOCSIS 3.1 orthogonal frequency-division multiplexing (OFDM)/orthogonal frequency-division multiple access (OFDMA) technology. This additional set of features significantly increases upstream capacity and allows for the same spectrum to be simultaneously used for both downstream and upstream.
The technology seminar will cover a wide range of topics, including:
- The physical layer: The physical layer topic includes how both OFDM and OFDMA have been extended to allow full duplex operation. This also includes how FDX DOCSIS (now DOCSIS 4.0 technology) fits into the channel plan, and how the system is expected to operate.
- The Media Access Control (MAC) layer: This topic includes both how the cable modem termination system (CMTS) manages the full duplex spectrum and how today’s FDX (now DOCSIS 4.0 technology) modems initialize and communicate with the CMTS for full duplex operation.
- Link Budgets and System Performance: This topic will discuss how to manage both signal levels and loss throughout the system in order to maintain peak operating performance.
- FDX DOCSIS support of existing DOCSIS modems: This topic concerns how FDX DOCSIS (now DOCSIS 4.0 technology) modems will be tested for backward compatibility with earlier versions of DOCSIS modems; they will all operate on the same cable plant with no need to upgrade older modems.
- Fiber Node changes: What will change in the Fiber Node, which now supports a Distributed Access Architecture (DAA) solution to distribute part (or all) of the CMTS to the fiber node?
- Node+0 Tips: These tips and considerations will focus on Node+0 (passive coax) plant construction to support FDX DOCSIS (now DOCSIS 4.0 technology).
The technology seminar has been designed to foster interactive discussion with the audience. FDX DOCSIS (now DOCSIS 4.0 technology) is an extension of the DOCSIS 3.1 technology and now involves the HFC network to create a system that offers symmetric capacity. Presentations will offer critical insights into these aspects of the architecture and technology. Attendees will come away with a greater appreciation and understanding of FDX DOCSIS’s (now DOCSIS 4.0 technology) underlying mechanisms.
The FDX DOCSIS technology (now DOCSIS 4.0 technology) seminar is free to attend and is open to all CableLabs members and DOCSIS NDA suppliers. The audience is intended to be composed of technology leaders involved with the early deployments of DOCSIS, including not only the DOCSIS engineers but also experts in outside plant and construction as FDX DOCSIS (now DOCSIS 4.0 technology) uses a Node+0 HFC network.
This technology seminar overlaps with an FDX DOCSIS (now DOCSIS 4.0 technology) interop being held at CableLabs the week of April 16. All CableLabs members and suppliers participating in the interop have the opportunity to tour the interop and witness FDX DOCSIS technology (now DOCSIS 4.0 technology) in operation, viewing—for perhaps the first time—the same spectrum carrying simultaneous upstream and downstream traffic.
With the CableLabs membership spanning five continents, the seminar will provide a unique opportunity for networking, as well as connecting or reconnecting with colleagues involved with the introduction of new DOCSIS technology. The seminar will offer a diverse set of deployment scenarios, and the discussions will include how FDX DOCSIS (now DOCSIS 4.0 technology) can support the needs of cable operators.
