NTT Lowers Its HK/Europe Latency Via TEA-2

August 8th, 2012 by · 2 Comments

Faster routes between the Far East and Europe have been a recurring theme lately. With NTT’s traditional Asian strength and its expansion plans in Europe, improving its connectivity between the two is obviously a priority. Indeed, today NTT Communications (NYSE:NTT, news, filings) took action to add a new route and significantly lower latency on its global backbone between London and Hong Kong.

They’ll be leasing wavelengths on the TEA-2 system. That’s the RosTelecom (and partners) cable across Siberia, which cuts the latency between the two major world internet hubs to sub 200ms. The subsea routes around India and through the Suez or across the Pacific, the USA, and then the Atlantic are generally 50-100ms longer by comparison.

Terrestrial routes across Asia have been getting more and more attention lately. Earlier this year, for instance, NTT’s Japanese rival KDDI and Rostelecom upgraded the TEA system to offer 10G wavelengths in combination with RJCN.

On the other hand, it is the proposed subsea routes through the Arctic that really carry a low latency kick, with some saying the Arctic Fibre system would take RTD down below 170ms as currently envisioned.  Seems as if NTT’s positive experience with in owning the PC-1 asset might get them interested in such a project.
