• EXA Infrastructure announced the 6,552km Meridian subsea cable between New Jersey and Brean, with service targeted for Q4 2029
  • The 24-pair system is designed for more than 500Tbps and will be built by a single operator rather than a consortium

The fact

EXA Infrastructure has announced EXA Meridian, a 6,552km transatlantic subsea cable planned between New Jersey in the United States and Brean on the Somerset coast of England. The system is scheduled to be ready for service in the fourth quarter of 2029 and will become the ninth transatlantic cable in EXA's portfolio.

Meridian is designed with 24 fibre pairs and more than 500Tbps of total capacity. EXA says it will be the first transatlantic cable built by a single operator in a decade, rather than through a consortium of co-investors.

The capacity figure is a design specification rather than the amount necessarily available when service begins. Spread evenly across 24 pairs, 500Tbps would equal about 21Tbps per pair, while the capacity actually lit and sold will depend on transmission equipment and customer commitments.

The assessment

Building Meridian through one operator removes some of the coordination required when several companies jointly fund and govern a cable. EXA can make project decisions without assembling a consortium of co-sponsors, which can simplify decisions during development and later upgrades.

That does not automatically tell customers what rights they receive. Buyers may take wavelengths, spectrum or complete fibre pairs under different commercial arrangements. Restoration priority, upgrade rights, maintenance procedures and changes to the route therefore need to be defined in the contract rather than inferred from the cable's ownership model.

The same distinction applies to the 500Tbps headline. Buyers planning transatlantic diversity need to know what capacity is available on their required route, how much is already committed and what happens when traffic must be restored after a fault.

For BTW readers, Meridian's single-operator structure concentrates those decisions with EXA rather than a consortium. Buyers will need contracts that define capacity, restoration and change rights clearly enough that their resilience plans do not depend on assumptions about how the system will be operated.

What to watch

Watch for disclosed customer commitments, fibre-pair or spectrum sales and the amount of capacity expected to be lit when Meridian enters service. Route surveys, landing infrastructure and construction milestones will show whether the Q4 2029 schedule is holding. Contract details around restoration and upgrades would clarify what large capacity buyers actually receive.
