NTT Upgrades PC-1 To 100Gbps

July 17th, 2013 by · Leave a Comment

After many tests and demos over the past few years, NTT has finally taken the 100G plunge beneath the Pacific ocean. The Japanese telecommunications giant announced this morning that it has deployed 100G coherent technology on its PC-1 cable system. The upgrade more than doubles the design capacity of the system to 8.4Tbps, and is already in place.

NTT Pacific Network MapNTT says that it wasn’t easy despite the demonstrations, that it was initially difficult to provide stable 100Gbps over what are some of the longest spans in use on the globe. But after optimizing their network architecture they were able to get past all remaining hurdles and more their infrastructure to transpacific 100G, albeit at less than the 10+Tbps total capacity they had been talking about in 2011.

PC-1, which NTT bought for a song a few years back, has become a cornerstone of the company’s global connectivity, carrying some 700Gbps for its transit backbone alone at last count.  By the end of 2014, they will have upgraded their pan-Asian regional ASE cable system to 100G as well.

The gear mentioned in the demonstration stages was Infinera’s DTN-X, but was not specified in today’s announcement.  Perhaps we will here more about that side of things in the coming weeks and months.
