TransTeleCom shifts all international backbone traffic to long haul DWDM

Russian communications service provider TransTeleCom has completed the shift of all international backbone traffic to a long haul DWDM network.

TransTeleCom’s long haul DWDM is a 20,000km transnational network with capacity of up to 80 optical channels with bandwidth of 100G each. The technology significantly increases the volume of traffic transmitted through one spectral channel and ensures the safe traffic for thousands of kilometres with a small number of regeneration points and minimal round trip delay. The company already holds nearly 20% of the global data transmission market between China and Europe, which is half the transit traffic market through Russia.

“There are high demands on modern multi-service transport networks. Long Haul surpasses all existing communication networks in Russia in speed, reliability and development potential. Latency between Frankfurt and Hong Kong is only 153ms. TransTeleCom has been gradually shifting the traffic of its international customers to the new network, and this process is now complete,” said Roman Kravtsov, president of TransTeleCom.

The project has created the world’s longest non-regenerated transmission span in land line networks — more than 4,000km. This is the length of the redundant route from St. Petersburg to Omsk. Its network architecture is optimal for fast, reliable traffic transmission. Standby switchover of channels in force majeure circumstances takes less than 50 milliseconds.

TransTeleCom plans to increase the number of traffic input/output points as part of the expansion of its long haul DWDM network.
