Since it announced its new DTN-X gear in advance of next year’s commercial sales, Infinera (NASDAQ:INFN, news, filings) has had a steady stream of big name trials and demos. Today it was Swedish telecommunications giant TeliaSonera AB (ETR:TLS, news, filings) taking the gear for a spin, but in California not in Europe. The two announced a Terabit optical transmission based on 500Gbps super-channels on a 1105km route between Los Angeles and San Jose.
It’s easy to forget that Teliasonera still has a terrestrial fiber footprint in the USA, given that nearly every other European operator retreated from the continent following the bubble a decade ago. Their fiber derives, I believe, from a swap with Williams Communications way back then which helps to power the company’s top 10 global IP backbone. That backbone is carrying 300Gbps on that route, according to the PR.
Teliasonera has been using Infinera gear on its US network since 2009, so trialing the DTN-X is an obvious move and probably does foretell an upgrade contract later on. It certainly does appear that 2012 is going to be the year 100G comes of age.
California is also one area Verizon put 100G into commercial operation earlier this year.
