  • Nokia to build new OTN for China Mobile

    Nokia to build new OTN for China Mobile

    Nokia announced that it will be providing China Mobile with an optical transport network that will enable the operator to become 5G-ready.

    China Mobile is currently building a new optical transport network that will support improved data center interconnection, consumer broadband services and 4G backhaul. Looking ahead, the new optical backbone will be a key part of the next-generation mobile services, namely 5G.

    “We are very pleased to work closely with China Mobile to provide the optical technology for its most advanced networks today and in the future. We’ll continue to fulfill our mission by making people’s life easier as we create the technologies that connect the world,” said Yu Xiaohan, head of the China Mobile customer team at Nokia Shanghai Bell, in a press release.

    Nokia described its solution as a dynamic, programmable optical network that can support virtualization and cloud technologies associated with 5G.

    According to Kyle Hollasch, head of marketing for Nokia’s optical business, China is the fastest growing region in the optical market.

    “As the only non-Chinese vendor with significant market share in China, Nokia is thrilled to be part of this strategic build-out for China Mobile,” Hollasch said in a statement.

    Nokia’s aspirations in China are well known. At Mobile World Congress (MWC) 2018 in Barcelona, Nokia CEO Rajeev Suri highlighted the race to 5G, saying it’s a battle between the US and China in terms of who gets there first. Both China and the US will move fast and they will be well ahead of pretty much every other part of the world, he said.

    Nokia and China Mobile used the MWC event to announce that they had signed an agreement under which the companies are jointly investigating how China Mobile can extend its service offerings for vertical markets using 5G. Their research is focused on how industries can benefit from the growth of smart cities, smart transportation and intelligent video analytics.

    The companies also are jointly testing use cases using Nokia 5G Future X network architecture as well as NB-IoT and MEC, and they’re expanding an existing Car2X trial ecosystem in Wuzhen to advance the use of automated vehicles, as well as technologies that improve vehicle safety.

    Nokia’s Nuage Networks was chosen by China Mobile (Suzhou) Software Technical Company, a subsidiary of China Mobile, as the SDN platform for China Mobile’s public and private enterprise cloud services offering. The platform is based on the Nuage Networks VSP and includes cloud implementations on virtual machines, Kubernetes (K8S) containers and OpenStack Ironic-based bare metal servers.

    Last year, China Unicom said it would use the Nokia Flexi Zone portfolio to densify its network where it isn’t possible to add a macro base station due to space or cost constraints.

  • Sydney Trains taps Ciena for OTN upgrade

    Sydney Trains taps Ciena for OTN upgrade

    Sydney Trains has contracted Ciena to help upgrade its network to a packet optical platform to improve public services across its transportation system with a faster, low latency and reliable data network.

    The deployment will support critical passenger safety measures that ensure trains in the Australian city operate at safe distances.

    By investing in both 100G transport and OTN switching solutions, Sydney Trains aims to build a network that enhances support of customer safety and critical train operations.

    The network upgrade will also help the transportation provider transition from an SDH legacy network, and lays the foundation required to support future high capacity service requirements.

    Sydney Trains has various sites along its network that have different traffic requirements. The flexibility of the platform supports these end-to-end services and various system configurations, including deployments over long distances and fiber types such as aerial.

    “For transportation providers, migrating their communication networks by deploying Packet-optical technologies is key to continually improving safety measures and optimizing passenger services,” Ciena VP and GM for APAC Anthony McLachlan said.

  • Spark deploys 200G OTN technology

    Spark deploys 200G OTN technology

    New Zealand’s largest operator Spark has deployed the market’s first 200G per wavelength production fiber link using equipment from Nokia.

    The operator’s new 200Gbps network link connects its core network with the global gateway, and will co-exist with Spark’s existing 10G and 100G channels.

    Spark general manager of networks Colin Brown said the upgrade is aimed at meeting massive growth in demand for bandwidth in an increasingly digital world.

    “Nokia has helped Spark NZ reach a new milestone with our world-class optical transport network, achieving our vision of a data-driven future for New Zealand and underpinning an integrated network including fiber, 3G, 4G, 4.5G, wireless broadband and Wi-Fi,” he said.

    Spark is using Nokia’s optical transport network technology. The vendor said it has now shipped its 200G solution to more than 88 customers worldwide, and demand is growing rapidly as operators see the benefits of 200G 8x quadrature amplitude modulation (8QAM).

    “Like many operators, Spark has faced relentless growth in bandwidth demand, largely driven by an increase in video streaming by business and consumer users,” Nokia head of Oceania Ray Owen said.

    “By taking a flexible approach to this challenge with New Zealand’s first 200Gbps fiber link, together with Nokia, Spark is well placed to meet continued demand growth while meeting existing user expectations.”
