Russian telecom service provider TransTeleCom (TTK) has launched commercial services over 100-Gbps ultra-long-haul DWDM routes between St. Petersburg and Moscow and between Moscow, Chelyabinsk, and Yekaterinburg. The fiber-optic network segments represent a total length of more than 3000 km and marks completion of first stage of TTK’s effort to deploy 100G nationally using coherent transmission technology from Cisco (NASDAQ: CSCO).
TTK has used the Cisco optical transport technology to increase the per-wavelength capacity of the segments from their previous high of 40 Gbps. The segments represent about 20% of TTK’s ULH network. The 2600-km route between Moscow and Yekaterinburg is the longest unregenerate land-line data transfer segment in commercial operation, Cisco asserts.
“The ULH DWDM technology is currently the most advanced in the world,” touts Artem Kudryavtsev, president of TTK. “It will increase the total throughput of TTK’s launched network sections by six times. Its implementation will guarantee new connection and data transfer quality for our corporate customers. TTK’s private customers can count on consistently high Internet connection speed even with rapid subscriber growth and a steady increase in TransTeleCom’s subscriber traffic. We are currently implementing the technology in other network segments”.
“TTK’s backbone network is the most advanced in Russia and is a crucial part of the country’s essential telecom infrastructure; its constant development and extension is of utmost importance not only for the company, but also for the whole communications market,” added Bill Gartner, vice-president, High-end Routing and Optical Group, Cisco. “We are pleased to cooperate with TTK in this project, and I’m sure that it will be long-term and productive.”
