Cisco announced the completion of a 100G technology test carried out by the North West Branch of MegaFon, one of the three largest mobile network operators in Russia.
Cisco and MegaFon specialists successfully tested data transmission at the rate of 100 gigabits per second in an existing MegaFon dense wavelength-division multiplexing (DWDM) network.
During the testing Cisco 100G solutions were successfully incorporated in networks based on other vendors’ technologies. The results proved that Cisco solutions are compatible with different manufacturers’ products, can be effectively used for multiple purposes, feature simplicity of configuration and usage, and prevent the necessity of deploying guard bands.
The project was aimed at testing the effectiveness and interworking of Cisco 100G transponders, Cisco ASR 9000 Series Aggregation Services Routers and the Cisco ONS 15454 Multiservice Transport Platform (MSTP) at the distance of 140 and 384 kilometers (87 and 239 miles). Additionally the solutions have been tested over "dark fiber" at 60 and 120 kilometers (37 and 74 miles).
Cisco ASR 9000 Series routers were used as the network core, as they had been designed as the foundational baseline for next-generation Carrier Ethernet networks.
They provide up to 96 terabits (Tbps) per system, helping ensure the fail-safe delivery of multifunctional applications.
The 100G services were supported by Cisco DWDM transponders tuned to 192.6 GHz (1556.55 nm). The transponders can operate at a distance well in excess of 3,000 kilometers (1864 miles) without signal regeneration, and they feature high performance and port density, thus enabling 100G technologies in networks of any complexity.
All parameters of the DWDM network were configured automatically by the smart-management subsystem and optical channel power control tools integrated in the Cisco ONS 15454 MSTP platform. During the test the traffic was transferred at 100 Gbps without failure and degradation of existing 10 Gbps services, showing the investment protection on the installed network and existing fiber plant.
"Cisco offers innovative solutions for next-generation DWDM networks, opening new opportunities for service providers. The testing proved that Cisco products show high performance over DWDM network, as well as over ‘dark fiber’, providing versatility and flexibility in implementation. Besides, the 100G services are compatible with existing services, avoiding the necessity of guard bands. Thus, the operator can maximize the potentiality of network bandwidth,” said Sergey Semenov, CTO, North West Branch, at MegaFon.
MegaFon is one of the three largest mobile operators in Russia. Moreover, they are the only company that launched its own network, providing a full range of mobile services across the country. In addition, subsidiaries of MegaFon work in Tajikistan, Abkhazia and South Ossetia.
