AEConnect submarine cable
Price and availability check
The invisible infrastructure of global connectivity
The AEConnect submarine cable is a high-capacity transatlantic cable system that directly connects North America and Europe. With its northern routing, AEConnect offers an important alternative to other transatlantic cables and contributes to route diversity on one of the world’s busiest data links. Submarine cables like AEConnect form the invisible foundation of global data traffic, with over 99% of international data flowing through them rather than through satellites or the cloud.
Route & connection
AEConnect connects Shirley (New York, USA) to Killala (Ireland), crossing the North Atlantic on a route specifically north of other transatlantic cable systems. This routing makes AEConnect a valuable option for companies requiring true physical redundancy on the North Atlantic. With a total length of approximately 14,000 kilometers, the cable provides a reliable direct connection between the North American and European markets.

AEConnect at a glance
What is the AEConnect cable?
AEConnect (also known as AEC-1) is a transatlantic submarine cable connecting Shirley, New York, with Killala, Ireland, and extending further to London and continental Europe via the CeltixConnect feeder cable. The cable spans around 14,000 kilometers, entered service in 2016 and reaches a capacity of up to 40 Tbit/s across four fiber pairs. AEConnect is operated by Aqua Comms and was built by TE SubCom, with Microsoft as its first anchor customer. Thanks to its northern routing, away from the more heavily used mid-Atlantic cable corridors, AEConnect offers genuine physical redundancy for companies already connected via more southerly systems.

AEConnect submarine cable

Technology & capacity
AEConnect uses modern fiber optic technology and offers a capacity of up to 40 Tbit/s, which meets the requirements of international companies with high bandwidth needs. Essentially, these are the technological features:
- Coherent transmission technology: AEConnect relies on state-of-the-art coherent optics, which enables efficient use of the available fiber capacity.
- Northern routing: The geographically independent route creates real physical redundancy compared to transatlantic cables running further south.
- Fibre optic technology with optimized signal amplification for stable transmission quality over the entire cable length.
Provider Overview
SAVECALL as access to AEConnect
Due to its northern routing, AEConnect is particularly interesting for companies that want to diversify their transatlantic connectivity. Anyone using two carriers on the same cable route today has no real redundancy, just a double bill. AEConnect creates a genuine alternative here. Access to capacity on AEConnect requires direct wholesale partnerships and in-depth market knowledge. This is exactly where SAVECALL comes in. We analyze your existing cable routes, identify physical overlaps and source capacity on AEConnect specifically as part of a well thought-out redundancy strategy.
The result for our customers:
- Direct capacity access to AEConnect without reseller chains
- Transparent price benchmarking and market data
- Genuine route diversity thanks to northern alignment
- Negotiation of IRU structures and leased capacity models
- Clear SLAs and ongoing capacity management

AEConnect compared
AEConnect deliberately positions itself on a northern route, away from the more heavily used cable corridors in the mid-North Atlantic. For procurement decisions, what matters most is whether a business needs a physically independent route to diversify existing capacity, or maximum raw capacity on the classic corridor. The comparison below positions AEConnect against Havfrue/AEC-2, Aqua Comms’ own successor system, and MAREA as an established southern alternative.
| Criterion | AEConnect | Havfrue / AEC-2 | MAREA |
|---|---|---|---|
| Route | US (Shirley, NY), Ireland (Killala) | US (New Jersey), Denmark (Blaabjerg), branches to Ireland and Norway | US (Virginia Beach), Spain (Bilbao) |
| Design capacity | up to 40 Tbit/s | 108 Tbit/s | around 200 Tbit/s |
| In service since | 2016 | 2020 | 2018 |
| Fiber pairs | 4 | 6 (main trunk) plus branches to Ireland and Norway | 8 |
| Strength | northernmost North Atlantic route, direct connectivity to Ireland and onward to London via CeltixConnect | same operator as AEConnect, first direct US-Scandinavia link in around 20 years | southernmost North Atlantic route, physically separate from more northerly systems |
Vendor-neutral assessment: SAVECALL does not rank AEConnect, Havfrue/AEC-2 and MAREA against each other, but views them as complementary building blocks for a resilient North Atlantic connection. Which cable or combination makes sense for a business depends on the required landing points, the desired route diversity and existing carrier relationships. As a carrier-neutral consultancy, we source capacity across all relevant systems and recommend purely based on actual requirements.

Frequently asked questions about the AEConnect cable
AEConnect connects Shirley, New York, with Killala on the west coast of Ireland. The CeltixConnect feeder cable extends connectivity further to London and onward into continental Europe. For companies with sites in the US, Ireland or the UK, AEConnect offers a direct, northerly transatlantic route.
AEConnect reaches a design capacity of up to 40 Tbit/s, spread across four fiber pairs using coherent 100G wavelength technology. This makes it one of the lower-capacity systems on the North Atlantic, but its independent northern route is its key advantage. For companies primarily seeking redundancy rather than maximum raw capacity, this is a sensible trade-off.
AEConnect entered service in 2016 and was built by TE SubCom. It is operated by Aqua Comms, which also runs the CeltixConnect feeder cable and the newer sister system Havfrue (AEC-2). Microsoft was the cable’s first major anchor customer, securing capacity early on for its cloud services.
This mainly depends on the landing points you need and the route diversity you’re after. AEConnect is a good fit for direct connectivity to Ireland and London, Havfrue suits connectivity toward Scandinavia and Denmark, and MAREA offers the classic route via Spain with high raw capacity. Combining a northern and a southern system is often the better choice to achieve genuine redundancy. SAVECALL advises on the right combination on a vendor-neutral basis.
Genuine redundancy only exists when the chosen cables use different landing points and physically separate routes, for example combining a northern route like AEConnect with a more southerly one like MAREA. Booking two carriers on the same cable route today still leaves you without real failover protection despite having two contracts. SAVECALL plans these concepts independently of any single cable operator, with a focus on the actual physical routing.
Access to capacity on AEConnect runs through direct wholesale partnerships with Aqua Comms as well as IRU or leased capacity agreements. SAVECALL negotiates these structures directly with the operator, without detours via reseller chains. Book a free consultation to discuss the right capacity solution for your business.
