EXA Express
Submarine communications cable system
From Wikipedia, the free encyclopedia
EXA Express (formerly Hibernia Express) is a submarine communications cable system linking Canada, Ireland, and the United Kingdom.[1] EXA Express is now owned by telecommunications provider EXA Infrastructure after their 2021 acquisition of the infrastructure assets of GTT Communications.[2] 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.[3]

The cable was considered operational on September 15, 2015.[4] EXA Express spans 4,600 km between its landing stations in Halifax County, Nova Scotia, Canada; Brean, Somerset, UK; and County Cork, 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 use Huawei 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 by TE Connectivity).[1]
