EXA Express (formerlyHibernia Express) is asubmarine communications cable system linkingCanada,Ireland, and theUK.[1] EXA Express is now owned by telecommunications providerEXA Infrastructure after their 2021 acquisition of the infrastructure assets ofGTT Communications.[2] With a latency of 58.95ms, the cable currently provides the lowest latency fiber optic route between the NY4 data center inSecaucus, New Jersey andLondon.[3]
The cable was considered operational on September 15, 2015.[4] EXA Express spans 4,600 km between itslanding stations inHalifax,Nova Scotia;Brean,UK; andCork,Ireland. The cable is constructed with six fiber pairs, with a design capacity for 53 Tbit/s.[3]
During the planning phases of the cable, Hibernia Networks intended to useHuawei as the contractor for construction.[5] However, due to security concerns from the potential customers, Huawei was not used and the construction contract went to TE Subcom (owned byTE Connectivity).[1]
