Kazakhtelecom JSC tests 100G with Coriant, Juniper Networks

Kazakhtelecom JSC says it has completed a field trial of a nationwide 100-Gbps fiber-optic network link trial. The trial used packet-optical transport equipment from Coriant and routers from Juniper Networks.

The trial, a prelude to rolling out 100G capabilities across Kazakhtelecom JSC's network, featured demonstration of integrated end-to-end provisioning of 100G services across a 1,575-km route between Aktobe and Astana. Individual spans ran as high as 130 km with a bit-error rate (BER) of zero, the carrier says.

"We currently have over 50 projects dedicated to the development and upgrade of our fixed line and mobile networks across Kazakhstan," said Nurlan Merimanov, 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. The scalability and flexibility of Coriant and Juniper's systems have been critical to our success."

The IP/MPLS DWDM infrastructure leveraged Juniper Networks' PTX 5000 and the Coriant hiT 7300 Multi-Haul Transport Platform. The two companies have collaborated on converged IP/optical transport since before Coriant was created (see "Nokia Siemens Networks, Juniper pair for IP over DWDM" and "Coriant, Juniper demo long-haul router, DWDM system interoperability").
