The Hibernia Express transatlantic cable has an actual tested latency of better than 58.95ms (milliseconds) from New York to London.

That's faster by more than half a millisecond off the original projected speed.

The new 4,600km submarine cable from Hibernia Networks is the first transatlantic cable built in over a decade. It underwent rigorous testing with parameters that included power stability, spectral efficiency and latency. The results confirmed the latency on Hibernia Express from LD4 in Slough, England, to NY4 in Secaucus, New Jersey, to be under 58.95ms capable of supporting content delivery for media and broadcast companies with real-time effect.

"Hibernia Networks is excited to announce that we not only have built the lowest latency transatlantic link connecting New York to London, but have also exceeded our original design goals with a tested latency of sub-58.95 milliseconds," said Bjarni Thorvardarson, CEO of Hibernia Networks. "Our team, along with our key partner, TE SubCom, has worked tirelessly to ensure the Hibernia Express cable system provides our customers with unmatched capabilities. The test results confirm that we are able to provide the lowest latency, highest capacity solutions to support the business objectives of our customers."

The six-fibre-pair cable features optical transport services up to 100Gbps for customers across various segments including financial markets, media and broadcast industries, Web-centric companies and telecommunications providers.

"According to our tracking of the transatlantic subsea cable systems, the new Hibernia Express cable offers improved latency performance of more than 20% on the sub-sea segment compared to the next fastest cable system connecting the North American and European continents," said Alan Mauldin, research director at TeleGeography.
