Hibernia Express is a submarine communications cable system that was privately owned by Hibernia Networks, linking Canada, Ireland, and the UK.[1] Hibernia Express is now owned by telecommunications provider GTT Communications, Inc. after their acquisition of Hibernia Networks.[2] [3] With a latency of 58.95ms, the cable currently provides the lowest latency fiber optic route between the NY4 data center in Secaucus, New Jersey and London.[4]
The cable was considered operational on September 15, 2015.[5] Hibernia Express spans 4,600 km between its landing stations in Halifax, Nova Scotia; Brean, UK; and Cork, Ireland. The cable is constructed with six fiber pairs, with a design capacity for 53 Tbit/s.[4]
During the planning phases of the cable, Hibernia Networks intended to use Huawei as the contractor for construction.[6] However, due to security concerns from the potential customers, Huawei was not used and the construction contract went to TE Subcom (owned by TE Connectivity).[1]
