NTT Takes Infinera’s 100G For a Transpacific Spin

October 11th, 2011 by · Leave a Comment

NTT Communications (NYSE:NTT, news, filings)‘s nascent 100G DTN-X technology has completed an important and quite impressive demonstration with the help of Pacific Crossing, the transpacific cable owned by NTT Communications (NYSE:NTT, news, filings).

They tested two technologies over a 9,500km span between California and Japan:

  • a 100 Gigabit Ethernet connection using 40Gbps optical channels
  • a true 100Gbps optical channel using BPSK and SD FEC that will be part of the DTN-X in the future

That second one I didn’t expect to see so soon on such a long subsea span.  According to ConnectedPlanet, BPSK was key to the distance achievement. Infinera’s DTN-X gear won’t be ready for commercial sales until the first half of 2012, but if a 100G solution works across the Pacific on a 10 year old cable, it can surely work on the various transatlantic submarine cables as well.

NTT is a known Infinera customer of course, but that has not been for undersea applications – although this was only a test of course. But NTT has long been interested in commercially feasible 100G, and its transpacific traffic requirements are already many multiples of that and rising quickly.
