Russian telecommunications provider TransTelecom has made a considerable investment in its infrastructure in order to shift all international backbone traffic to a Long Haul DWDM network.

TransTelecom owns of one of the most expansive fiber optical networks in the world, spanning 76,000 kilometers between Europe and China.

Dense Wavelength Division Multiplexing (DWDM) technology enables operators to increase bandwidth over existing networks by combining and transmitting multiple signals on the same fiber, using different wavelengths.

TransTelecom says modern technology has enabled it to increase bandwidth, reduce the number of regeneration points and ensure minimal round trip delay.

TransTelecom was established in 1997 to create a digital backbone suitable for the needs of Russian Railways. Today, it is responsible for around 50 percent of all transit traffic coming through Russia.

The company’s new 20,000 km Long Haul DWDM network offers capacity for up to 80 channels, with 100G of bandwidth each. It has set a record the world’s longest non-regenerated transmission span – 4,000km of fiber without any additional nodes usually required for traffic regeneration.

“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,” said Roman Kravtsov, president of TransTelecom.

“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.”

In the future, TransTelecom plans to increase the number of traffic input and output points as part of the expansion of the Long Haul DWDM network. This will increase network availability for both foreign and domestic customers.
