  • Airtel taps Ciena for high-speed backbone network

    Airtel taps Ciena for high-speed backbone network

    India’s Bharti Airtel has contracted Ciena to deploy a large-scale photonic control plane backbone network that will connect more than 4,000 towns across the nation.

    Under the agreement, announced at Mobile World Congress in Barcelona, the companies will collaborate to deploy a network spanning 130,000km.

    The network deployment, which the companies said will be one of the world’s largest photonic control plane deployments, forms part of Airtel’s Project Leap network transformation program.

    Airtel plans to use the network to serve exploding demand for high-speed data services, and to enable the delivery of high-speed broadband to end users over 4G/5G/FTTH architectures.

    For retail and enterprise customers, the network will also support bandwidth on demand, optical VPNs, latency based routing and dynamic data center interconnection.

    Airtel CTO Randeep Sekhon said the backbone architecture will be capable of working with data rates of 400Gbps and higher, and delivering low-latency software-controlled connectivity for cloud infrastructure.

    “Airtel has always pioneered the introduction of cutting-edge network technologies to serve its customers. We are pleased to work with Ciena to build one of world’s largest optical spine and leaf networks, which is also a big step towards 5G readiness by leveraging our huge fiber assets,” he said.

    “This will not only scale our network for massive capacity but also protect traffic and enhance service delivery to all our customers. It will also help Airtel further strengthen its position as a key enabler of digital experiences in an increasingly connected world.”

  • Telstra sets speed record with metro network trial

    Telstra sets speed record with metro network trial

    Australia’s Telstra, Ericsson and Ciena say they have achieved the world’s fastest speeds during a demonstration using Telstra’s transmission network in Melbourne.

    The companies achieved 400Gbps speeds over 61.5-GHz spectrum using Telstra’s transmission network, representing the highest spectral efficiency per fiber pair achieved in a live environment.

    This represents transmission speeds of up to 30.4Tbps per fiber pair, a significant improvement from the previous record of 25.6Tbps.

    Such speeds were made possible using software programmable wavelengths controlled by Ciena’s WaveLogic Ai modem technology and Blue Planet manage control plan and Liquid Spectrum applications.

    Telstra plans to introduce the technology as part of an upgrade to its long haul, metro and regional optical networks. Ericsson is providing end-to-end systems integration for the project and managed the deployment of technology for the demonstration.

    Telstra has already deployed Ciena’s industry-first programmable coherent modem, which offers up to three times the data capacity of the earlier modem technology deployed on the Telstra network.

    “Over the next five years we forecast traffic on our network will grow by five times. We are investing in our network and developing these innovations to meet this growing demand by providing unprecedented levels of scale, automation and intelligence,” Telstra director of IP and transport engineering David Robertson said.

    “This technology will be deployed in our domestic transmission network and we will look for opportunities to use it in Telstra’s international subsea cable network, which is the largest in the Asia-Pacific region.”

  • Nokia, Ciena providing gear for Jio’s major 4G rollout

    Nokia, Ciena providing gear for Jio’s major 4G rollout

    Nokia and Ciena have both detailed their roles in providing equipment for disruptive Indian newcomer Reliance Jio Infocomm’s greenfield pan-India 4G rollout.

    Reliance Jio finally launched LTE services for the public in September last year, and has signed on 100 million new users in just 170 days due to its aggressive strategy of initially offering all services for free.

    Nokia announced that its optical deployment for Jio covers over 90,000km across India, making it one of the biggest 100G deployments in the world.

    The vendor provided switches with 100G DWDM capabilities as well as generalized MPLS intelligence to support capacity management and restoration

    “In only 170 days, Jio has signed on 100 million new users. With growth rates of this magnitude we had to ensure we deployed the highest capacity, most resilient transport network to build out the 4G network,” Reliance Jio president Jyotindra Thacker commented.

    “Nokia’s next-generation DWDM portfolio provides the ability to scale easily as Jio continues to expand the network to reach the underserved areas of India with digital services in key areas such as communication, education, healthcare, payments and multi-media entertainment.”

    Ciena meanwhile deployed multi-terabit converged packet optical technology for Jio’s 4G network core, operating at speeds of up to 200Gbps.

    The Ciena packet optical platforms use Ciena’s WaveLogic coherent technology for the core network, which connects all major cities of India.

    • “With Ciena we are not only able to provide robust scalability to offer new levels of data consumption, which is already 8 to 10 times above market levels, but also a supreme level of confidence in our network’s reliability and level of service that stands out in our marketplace,” Thacker said.
    • “Ciena’s coherent technological offerings and proven control plane technology is helping to make us the fastest growing 4G network in the world.”

  • Ciena aims to usher in age of self-driving network

    Ciena aims to usher in age of self-driving network

    Ciena has unveiled WaveLogic Ai, a programmable coherent modem that aims to serve as a  foundational enabling technology for a self-driving network.

    WaveLogic Ai sets new performance benchmarks designed to improve transport network economics and flexibility across a broad set of network applications.

    In metro and DCI applications, it drives 400G single carrier transmission with power and density metrics. In regional and long-haul networks, WaveLogic Ai establishes 200G and 300G as the new reference line rates for backbone transmission, doubling capacity and dramatically lowering cost per bit. In submarine networks, it provides maximum capacity with ultimate reach at distances up to 14,000 kilometers.

    WaveLogic Ai offers enhanced intelligence for new levels of visibility into the network that enables autonomous decisions to further improve network performance.

    Through open interfaces, it monitors and gathers critical networking data, including embedded real-time link measurements, to make intelligent capacity decisions in real time. For instance, WaveLogic Ai helps determine the optimal capacity for any path across the network and can tune to different capacity levels from 100G to 400G in 50G increments.

    WaveLogic Ai uses an advanced 400G-optimized technology engine with a higher baud rate to drive twice the capacity per channel, three times the distance at the equivalent capacity, and four times the service density at less than half the power. This scalability supports 400GE and flexible client services to best match service throughput to flexible line capacity.

    WaveLogic Ai is designed to calculate and then make available massive amounts of optical networking performance data through open interfaces that can be mined to build on-demand, programmable networks.

    To better match capacity to system margin, WaveLogic Ai provides unprecedented tweakability via open software interfaces that help drive automated and intelligent decisions to reduce operational expense and avoid manual errors.

    WaveLogic Ai provides access to real-time link monitoring information, thereby giving operators new levels of network visibility and the ability to accurately engineer the network for optimal capacity and maximum efficiency.

    The company says WaveLogic Ai will be available in the second quarter of 2017.
