ESnet Extends 100G Connectivity links Between U.S and Europe

ESnet (BERKELEY, Calif.—The Department of Energy’s (DOE’s) Energy Sciences Network) will be deploying four high speed connectivity links across the Atlantic enabling researches at America’s national laboratories and universities ultra-fast access to scientific data from the Large Hadron Collider (LHC) and other research sites in Europe.

ESnet believes that by delivering a capacity of 340 gigabits-per-second to dozens of scientific collaborations, it will provide “advanced networking capabilities and tools to support U.S. national laboratories, experimental facilities and supercomputing centres”.

Some of the scientists likely to benefit from this boost in connectivity include researchers “at the Large Hadron Collider (LHC), the world’s most powerful particle collider, located near Geneva, Switzerland. DOE’s Brookhaven National Laboratory and Fermi National Accelerator Laboratory—major U.S. computing centres for the LHC’s ATLAS and CMS experiments”.

The connectivity will occur through under the sea network capacity that is leased from existing suppliers. Each cable will have “several pairs of optical fibre, with one fibre in each pair used for sending data from the U.S. to Europe, and the other used for data moving in the reverse direction. Each fibre is “lit” using dense wavelength division multiplexing (DWDM), a technology that sends data from different sources using different colours of light, allowing between 40 and 80 different signals to be sent on a single fibre simultaneously”.
