Kazakhtelecom JSC has completed a live field trial demonstrating a nationwide 100 Gigabit-per-second (100G) optical network connection.
The trial is part of several expansion projects that the operator is undertaking, with the ultimate goal of expanding its high-performance, high-bandwidth fibre optic network to transmission rates of 100G addressing the ever-increasing demand for faster, more reliable and cost-efficient broadband business and consumer services in Kazakhstan.
The operator selected Coriant and Juniper Networks to provide the required Integrated Packet Transport Network (IPTN) to build a converged packet optical national backbone. The IPTN field trial featured integrated end-to-end provisioning of 100G services across a seamless and resilient Internet Protocol/Multiprotocol Label Switching (IP/MPLS) Dense Wavelength Division Multiplexing (DWDM) infrastructure optimized for existing and new high-speed services and applications in and through the Kazakhtelecom JSC network.
The network architecture collaboration between Juniper and Coriant includes a provisioning framework for 100G DWDM services originating from Juniper Networks’ PTX 5000 to the Coriant hiT 7300 Multi-Haul Transport Platform. The IPTN field trial ran 1,575km between Aktobe and Astana.
The flexibility of the IPTN solution allowed Kazakhtelecom JSC to successfully conduct the field trial alongside an existing 100G coherent network carrying live traffic, demonstrating the engineering robustness of the IPTN network architecture. During the trial on this link, which included spans reaching up to 130 km in length, the network performed perfectly with a zero bit error rate and sufficient margin to cover future network expansion.
“We currently have over 50 projects dedicated to the development and upgrade of our fixed line and mobile networks across Kazakhstan," said Nurlan Meirmanov, Managing Director of Innovations, Kazakhtelecom JSC. “With the achievement of this field trial, the IPTN solution shows that we can reduce the operational costs and decrease the delay in provisioning of new services in the IP layer as well as in the optical transport layer.”
“This will bring us to the next step in our network upgrades that will enable the feature of multi-layer Generalized Multiprotocol Label Switching (GMPLS) control plane for automated service provisioning”, he added.
