Subsea Cable Production Doubles as 2028-2029 Transatlantic Routes Target AI Traffic

Lead times extend as manufacturing capacity targets 2028-2029 deployments

Prysmian has doubled submarine telecommunications cable production capacity at its Nordenham, Germany facility, adding up to 300 jobs and positioning to supply EXA Infrastructure's 6,552-kilometer EXA Meridian transatlantic system scheduled for 2029 service. The expansion follows Prysmian's 80% stake in subsea-systems provider Xtera through a joint venture with Fincantieri, strengthening its position against NEC, ASN, and SubCom in a market where cable production and vessel availability increasingly constrain new routes.

For enterprise buyers, the relevant signal is timing, not immediate supply relief. The most concrete systems cited—EXA Meridian and the Pisces cable connecting Ireland to France, Spain, and Portugal—enter service in 2028 and 2029. Organizations planning transatlantic capacity or geographically diverse disaster-recovery routes face a decision: reserve wavelength, spectrum, or dark-fiber capacity on existing systems now, or accept exposure to vessel schedules, permitting delays, and equipment availability beyond procurement control.

Pisces cable offers Ireland-to-continent path independent of UK transit

Orange, infrastructure investor Equitix, and Irish subsea designer MDM are developing Pisces, a planned 3,125-kilometer, 16-fiber-pair cable connecting Ireland with landing points in France, Spain, and Portugal. The system has European Union Connecting Europe Facility support, targets 2028 deployment, and is designed as open-access dark fiber for carriers, cloud providers, and data-center operators.

The competitive shift is route independence. Pisces would give Irish data centers a direct path to continental Europe without transiting the United Kingdom, reducing exposure to a single geographic bottleneck. The announcement does not disclose total cost, ownership shares, aggregate capacity in Tbps, or committed customer contracts, so the benefit remains prospective pending construction, permitting, and landing-station agreements.

For Irish enterprises and cloud operators evaluating continental connectivity, the relevant questions are landing-station access, restoration arrangements, and whether capacity will be sold as spectrum, wavelengths, or fiber pairs. Open-access design could improve supplier choice, but pricing and availability are unknown until the system is operational.

Midwest corridor targets secondary AI and data-center markets

Midwest Fiber Networks, Midwest Fiberpath, and Hawkeye Land Co. announced an agreement to develop approximately 1,200 miles of fiber corridors connecting Chicago, Omaha, Minneapolis, and Kansas City. The project is expected to add conduit, dark fiber, and lit services for carriers, hyperscalers, utilities, enterprises, and public-sector users, with construction targeted for spring 2027.

The corridor connects secondary data-center and AI-infrastructure markets rather than concentrating on established coastal hubs, potentially adding route diversity for enterprises deploying distributed AI, backup sites, or multi-region applications. No construction cost, route-level pricing, committed customers, fiber count, or completion date beyond the spring 2027 construction target was disclosed. This is a credible infrastructure pipeline development but currently insufficient as a basis for near-term budget changes.

Capacity decisions favor early reservations over waiting for new builds

Prysmian's manufacturing expansion adds supply capacity but does not disclose customer pricing, system cost, or available Tbps, supporting a tighter-capacity thesis rather than a near-term reduction in connectivity prices. Industry analysts at Capacity Europe reported that investment is lagging demand in long-haul and subsea networks, with value concentrating around bottlenecks including power, strategic sites, scarce routes, and trusted interconnection.

For enterprises, that points to higher value in early reservations and geographically independent connectivity than in simply buying more bandwidth at a single location. The most relevant systems cited here are scheduled for 2028-2029, so near-term buyers should continue securing existing capacity rather than waiting for new cables.

Route diversity requires evaluating physical-path independence, landing-station diversity, restoration SLAs, and exposure to common ducts or terrestrial backhaul. Competitive pressure is more likely to emerge through additional routes and open-access models than through immediate commodity pricing.

What to watch

Monitor construction progress and landing-station agreements for Pisces and the Midwest corridor. Track whether open-access commitments translate into published pricing for spectrum, wavelengths, or dark fiber. For transatlantic capacity, verify whether existing providers offer capacity reservations or pre-commit pricing for 2028-2029 systems, and compare against current spot and term rates to quantify waiting costs. Organizations with disaster-recovery or compliance requirements should audit current route diversity and identify whether planned systems reduce exposure to UK transit, coastal concentration, or single-duct dependencies.
