Vodafone teams with Huawei for 10G over fibre in Spain

Vodafone and Huawei announced that at Mobile World Congress they demonstrated an ultra-fast fibre broadband connection delivering a download speed of nearly 10 Gbit/s designed to support services such as ultra HD (UHD) 8K video, big data, virtual reality (VR) and 3D augmented reality (AR), remote healthcare and online gaming.

At MWC, Vodafone demonstrated simultaneous support for viewing of UHD 4K video and data download at gigabit speeds.

Vodafone Spain announced in January that it planned to upgrade its hybrid fibre-coaxial (HFC) network to enable symmetrical data rates of more than 1 Gbit/s upstream and downstream. In addition, the operator noted that in addition to upgrading its existing network to DOCSIS 3.1, it planned to implement a new distributed architecture involving extending fibre closer to optical sites to deliver higher bandwidth for end users.

For the project, Vodafone Spain has adopted Huawei's DOCSIS 3.1-based distributed converged cable access platform (D-CCAP) solution as part of a DOCSIS 3.1 network deployment designed to offer advantages including: increased bandwidth per user by expanding the spectrum range and improving modulation efficiency; improved operation and enhanced network quality; greater flexibility and scalability, with the ability to upgrade the HFC network or deploy a full FTTH network.

Vodafone noted that work to modernise the network has commenced in the main cities in Spain, and will extend to the whole country over the forthcoming months.

In mid-2016, Huawei and Vodafone Spain announced the launch of Madrid Tech City, a project intended to position Madrid as a leading global technology city. The companies noted that the initiative had already provided access to 4G+ mobile network with peak data rates of 600 Mbit/s. Vodafone and Huawei also planned to implement NB-IoT (narrowband - Internet of Things) technology to connect devices and sensors and enable the launch of new services such as: intelligent parking.

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.

NBN Co Selects ARRIS for New Australian HFC network

NBN Co has selected ARRIS to build a next-generation Hybrid Fiber-Coaxial (HFC) network for Australia's broadband network. Financial terms were not disclosed.

NBN Co expects that using HFC technology will yield significant cost savings for Australian tax-payers over its previous FTTH network design.

ARRIS said its platform will allow NBN Co to enhance and manage its cable access network while providing a roadmap for possible future migration to DOCSIS 3.1 architecture. The initiative involves its flagship E6000TM CER (Converged Edge Router) along with a number of additional ARRIS product lines, including: ARRIS Access Technologies and Supplies (ATS) products (CORWave forward path transmitters and OM4100 optical receivers) and Assurance solutions for service assurance. Additionally, ARRIS's Global Services was selected for the full deployment and network integration of this national broadband service. In addition, ARRIS Global Services group will assist NBN Co in managing and supporting its network and customers.

NBN Co CTO, Dennis Steiger, said: "An HFC network represents the fastest and most cost-effective way to deliver it to consumers and businesses in the existing HFC network areas. Our goal is to achieve high-speed broadband as quickly possible, with an eye on future technologies that will secure our place as a global technology leader." Steiger continued: "Significant investments are being made in HFC broadband technology on a global scale, and we are committed to ensuring that Australia is at the forefront of this movement."

Bruce McClelland, President of Network & Cloud and Global Services at ARRIS added: "ARRIS is honored to be selected by NBN Co for this exciting project and whole-heartedly endorses the use of HFC technology to proliferate Broadband across Australia. The ARRIS portfolio of Products and Services are at the heart of many Broadband networks around the world, and we look forward to expanding our presence in the Asia Pacific region. We are delighted to be working with NBN Co at such an important stage in this initiative."

In December 2014, Australia's NBN Co announced a new national rollout plan for the National Broadband Network (NBN) based on a multi-technology access strategy, including fiber to the premise (FTTP), fiber to the node (FTTN), wireless and upgraded HFC. 

Areas where NBN FTTP has been deployed or is in advanced stages of being built will likely remain part of the FTTP rollout, while areas served by the Optus or Telstra Hybrid Fibre Coaxial (HFC) cable networks will likely receive fast broadband over an upgraded HFC network.

The plan covers the next 1.9 million homes and businesses by mid-2016 across more than 400 cities, suburbs and towns, on the path to achieving 8 million connections to the NBN by 2020.

Germany's Tele Columbus Readies 400 Mbps DOCSIS

Tele Columbus Group, the third largest German cable network operator, is preparing to launch a consumer broadband service with a top downlink speed of 400 Mbps.

The company said its service will be launched in April 2015, starting in the region of Potsdam – in Brandenburg’s state capital, where a total of 40,000 households are connected to its city network.

Tele Columbus features a hybrid glass-fiber coaxial structure with a FTTB (fiber-to-the-building) approach and operates on DOCSIS 3.0 technology. Tele Columbus Group’s multimedia networks are also distinguished by a relatively high number of fiber nodes for provision of the connected households. The company also offers a Wi-Fi cable box designed to accommodate data rates of up to 1.3 Gbps inside the home.

To increase Internet speeds to the new high of 400 Mbps in Potsdam, Tele Columbus is investing in further network infrastructure improvements, including new active components in the local head-end facility.
