CableLabs completes Full Duplex DOCSIS 3.1 spec

CableLabs has completed its Full Duplex DOCSIS 3.1 specification, significantly increasing upstream capacity and enabling symmetric multi-Gigabit services over existing hybrid fiber-coaxial (HFC) technology. Full Duplex DOCSIS 3.1 technology builds on the DOCSIS 3.1 specification, which made deployments of 10 Gbps downstream and 1 Gbps upstream broadband possible.

Full duplex communication enables upstream and downstream traffic to efficiently use the same spectrum simultaneously. In contrast, spectrum is typically split between the upstream and downstream in current DOCSIS implementations.

“In the United States, more than 90 percent of households are connected to an HFC network, and consumers typically have higher download speeds than upload speeds,” said Phil McKinney, president and chief executive officer of CableLabs. “By enabling Full Duplex DOCSIS, the upstream and downstream traffic can flow at up to 10 Gigabits concurrently, doubling the efficiency of spectrum use.”

CableLabs: Thinking about the Implications of 5G



In this 2-minute video, Pete Smythe, VP, Core Innovation, CableLabs, discusses some of the implications of 5G, including the impact of ultra-low latency on fixed mobile convergence.

Another area of interest is unlicensed spectrum for LTE and WiFi, where we can anticipate an intersection of mobile networks and fixed-line networks, as well as an overlapping of public and private networks in hospitals, factories, etc.

Nokia Bell Labs Hits 10 Gbps Symmetrical with XG-Cable

Nokia Bell Labs has demonstrated a prototype XG-CABLE solution that achieves full duplex 10 Gbps rates over a traditional Hybrid Fiber Coax (HFC) cable systems and based on CableLabs' DOCSIS 3.1 architecture.

Specifically, the XG-CABLE test used two different cable scenarios:

  • Leveraging a point-to-point 100m coaxial drop cable, XG-CABLE was able to deliver 10 Gbps symmetric data speeds with 1.2 Ghz of spectrum 
  • Using HFC network topologies that utilize a Fiber-to-the-Last-Amplifier (point-to-multipoint coax drop) approach, XG-CABLE was able to deliver 7.5 Gbps of symmetrical data speeds.

Nokia Bell Lab's XG-CABLE utilizes innovative echo canceling technologies developed by Bell Labs to achieve full duplex transmission of 10 Gbps upstream and 10 Gbps downstream simultaneously.

"The XG-CABLE proof of concept is a great example of our ongoing effort and commitment to provide the cable industry with the latest innovations and technology needed to effectively address the growing demand for gigabit services. The proof of concept demonstrates that providing 10 Gbps symmetrical services over HFC networks is a real possibility for operators; it is an important achievement that will define the future capabilities and ultra-broadband services cable providers are able to deliver," stated Federico Guillén, President of Fixed Networks, Nokia.

A whitepaper is posted online.

CableLabs Eyes Symmetric Multi-Gigabit DOCSIS

During its recent 2016 Winter Conference, CableLabs unveiled a Full Duplex DOCSIS technology that aims for multi-gigabit rates.  The breakthrough increase in the upstream speeds for DOCSIS delivered broadband service is achieved by applying emerging techniques from wireless networks to the cable infrastructure.

CableLabs said this new approach significantly increases upstream data capacity in order to enable symmetric multi-Gigabit broadband data services for consumers and the enterprise. These developments are expected to yield DOCSIS 3.1 network performance of up to 10 Gbps symmetrical on 1 GHz HFC networks, with the potential for even higher performance by utilizing spectrum that is currently available for future expansion above 1 GHz.

CableLabs Awards First DOCSIS 3.1 Modem Certifications

CableLabs awarded the first DOCSIS 3.1 certifications to five cable modem vendors: Askey, Castlenet, Netgear, Technicolor and Ubee Interactive. Certification verifies compliance to the specifications, interoperability among products and enables competition and choice in the marketplace.

DOCSIS 3.1 technology is designed to meet the demand for higher speeds cost effectively by improving network efficiency and scalability while operating on existing cable operator networks, maintaining backward compatibility with existing DOCSIS deployments. DOCSIS 3.1 technology also reduces network latency, and so dramatically improves responsiveness for sophisticated applications such as gaming and rich web experiences. Cable operators can deploy multi-gigabit services over their existing Hybrid Fiber Coax networks based on consumer demand, leveraging their existing network infrastructure and DOCSIS devices to enable a smooth migration to the new capabilities of the DOCSIS 3.1 technology. This also represents the first set of DOCSIS specifications with worldwide applicability, a key element to delivering rapid scale and cost-effective products.

“Today’s news marks a key milestone for CableLabs in technical leadership and time to market,” said Phil McKinney, President and CEO of CableLabs. “The DOCSIS 3.1 specifications assure the cable industry’s leadership in the delivery of broadband services. This represents the most rapid development and implementation cycle for a broadband technology development program ever delivered by CableLabs. Development of the initial DOCSIS 3.1 specifications to product certification has occurred in half the time of previous DOCSIS specifications.”

CableLabs Details New Remote PHY Specs for DOCSIS

CableLabs posted information on several different Distributed CCAP Architectures (including Remote PHY and Remote MAC-PHY).

Last month, CableLabs publicly issued the Remote PHY family of specifications. Theses specifications are also known as MHAv2 as these are an evolution from the original Modular Headend Architecture specifications.

In a blog posting, Karthik Sundaresan, Principal Architect, CableLabs, describes how the Remote PHY technology allows for an integrated CCAP to be separated into two components: the CCAP Core and the Remote PHY Device (RPD) with interfaces between them. One of the common locations for an RPD is the optical node device that is located at the junction of the fiber and coax plants, while the CCAP Core stays at the headend. A CCAP core can control and setup data paths with multiple RPDs situated in multiple fiber nodes.

CableLabs said it will release the set of technical reports and specifications throughout this summer.

Broadcom's EPON ONU and OLT Chipsets Support DOCSIS Provisioning

Broadcom confirmed that its end-to-end EPON ONU and OLT chipsets and DML software are ready to be deployed in DOCSIS provisioning of EPON (DPoE) 1.0 environments.

Broadcom said the 1G EPON and 10G EPON access technologies offer the bandwidth, scale, and features required to deliver demanding business and mobile backhaul services. CableLabs DPoE 1.0 specification fully supports the DOCSIS provisioning processes.

The company has been collaborating with CableLabs, multi-system operators (MSOs) and industry OEMs on defining the requirements for the DPoE 1.0 specifications.

“The DPoE specifications represent a significant achievement on the part of CableLabs, cable MSOs and industry OEMs to create an open standard that achieves full vendor and equipment interoperability. This will further the growth of the cable industry by meeting the bandwidth needs of business users,” said Greg Fischer, Broadcom Vice President and General Manager for Broadband Carrier Access. “As an early supporter of the technology, Broadcom has devoted significant resources to both the standardization process and our product portfolio to make DPoE technology available today.”

CableLabs recently qualified DPoE 1.0 Systems and ONU products through its certification process.
