The European Space Agency has selected neXat, Telesat and Colt Technology Services Belgium to develop CableShield, a system intended to reroute a prioritized share of network traffic over satellite when a submarine cable is disrupted. It is a funded development and validation project—not an operational backup service—and satellite is not expected to replace the capacity of subsea fiber.
What ESA selected and what CableShield is meant to do
neXat is leading the 18-month CableShield development and validation activity with Telesat and Colt Technology Services Belgium. neXat’s September 15, 2026 announcement gives the project value as €1.5 million; Data Center Dynamics reported the equivalent as $1.68 million on October 5, 2026. These are reported project values, not an independently audited contract disclosure. ESA says the work is funded under its Space Systems for Safety and Security (4S) program within ARTES.

The aim is to coordinate terrestrial network controls with satellite capacity so network operators can redirect selected affected traffic when a submarine cable route fails or is otherwise unavailable. CableShield is not a cable-repair system, a consumer satellite router, or a way to transfer every bit of a busy subsea route onto satellite.

How the planned backup path would work
The proposed system combines fault response with network and satellite-resource management. Its intended sequence is:
#1 Best Overall
- Please REMOVE the end protective caps before using the cable.
- IN THE BOX: 6-foot digital optical audio Toslink cable.
- CLEAR AUDIO: Multi-channel, fiber-optic digital audio output; corrosion resistant gold-plated connectors and buffer tubing for optimal signal transfer.
- DURABLE: Lightweight, flexible cable with a rugged PVC exterior and removable rubber tips that protect the cable when not plugged in; remove before using.
- CONNECTS DEVICES: Quickly connects a sound bar, CD player, Blu-Ray player, game console, or other device to an audio system or TV.
- Detect and confirm an interruption to a cable route.
- Coordinate the response across detection and decision functions, terrestrial network controls, and satellite controls.
- Select available satellite resources and allocate capacity to authorized users.
- Use routing and traffic-prioritization mechanisms to establish an end-to-end path for a controllable share of affected traffic.
neXat describes its operator-agnostic OSS/BSS platform as the orchestration layer for pooling satellite capacity and allocating bandwidth after a fault is confirmed. The three infrastructure layers are expected to exchange information through APIs defined in ESA’s Pooling and Sharing Interface Definitions (PSID) activity. The stated purpose of PSID is to support data exchange, capacity requests, and shared-resource management across multi-vendor, multi-orbit satellite systems.
Why pool capacity?
The “Pooling & Sharing” model is intended to let capacity from multiple satellite providers be combined, rather than tying the backup concept to a single provider. Telesat is the only provider named as the initial capacity source: the announcement says its Lightspeed low-Earth-orbit constellation is expected to connect first. The project’s multi-provider design does not establish that additional providers have signed on.

Whether as a primary cable or a spare for your underwater setup, it’s a trustworthy solution that gets the job done.
What each partner brings
| Partner | Planned contribution |
|---|---|
| neXat | Prime contractor and provider of the operator-agnostic OSS/BSS platform intended to orchestrate satellite resources. The company says its platform is built on its “HUB Bypass” patent and is used in government satellite communications projects. |
| Telesat | Expected initial satellite-capacity provider through Lightspeed. neXat’s announcement describes the constellation as designed for low latency and fiber-like connectivity, with onboard processing and optical inter-satellite links; these are design descriptions, not measured CableShield results. |
| Colt Technology Services Belgium | Contributor of the IQ Network and traffic-engineering capabilities for programmable terrestrial routing. neXat cites the network as spanning more than 40 countries, connecting 1,100 data centers, and incorporating 10 subsea systems and 12 landing stations. |
| European Space Agency | Selected and funded the development work under the 4S program within ARTES, according to neXat’s announcement. |

Why satellite backup is for selected traffic, not the whole cable
Submarine fiber routes carry far more capacity than a satellite backup path can be assumed to provide. CableShield’s described role is narrower: prioritize important traffic during an interruption, especially when other terrestrial routes are not available, while the damaged route is restored. Which traffic qualifies and how much satellite bandwidth would be available depend on the eventual system and capacity arrangements; the published descriptions do not quantify either.
neXat’s September 2026 announcement says roughly 30% of tracked submarine cables experience at least one fault each year, that typical repairs take 10 to 20 days, and that submarine cables carry an estimated 99% of intercontinental data traffic. The announcement does not provide underlying datasets for those estimates, so they should be read as neXat’s context figures, not independently verified statistics. Separately, neXat COO Caroline De Vos described submarine cables as carrying “an estimated 99% of global connectivity”; that is her quoted company statement and uses broader wording than the announcement’s intercontinental-traffic figure.

The project is planned to move from requirements definition to a laboratory demonstration and then field trials over 18 months. neXat has targeted a commercial CableShield launch in 2028, aligned in its announcement with Telesat Lightspeed’s planned Q1 2028 commercial service entry. Both dates are plans, not completed milestones or guarantees of availability.

No measured CableShield throughput, latency, recovery time, or field-trial results have been published in the cited coverage. The announcement’s descriptions of Lightspeed or Colt’s network should therefore not be mistaken for demonstrated end-to-end CableShield performance.

- Established: ESA selected a consortium led by neXat, with Telesat and Colt Technology Services Belgium, for a funded development project.
- Planned: The system is intended to coordinate terrestrial routing and pooled satellite capacity to carry selected traffic after a confirmed cable interruption.
- Not yet demonstrated publicly: The system’s actual throughput, latency, failover time, field performance, and the volume or types of traffic it can support.
- Not established: A consumer signup or purchase route, an operational service, or confirmed participation by satellite providers beyond Telesat as the expected initial provider.
neXat COO Caroline De Vos called satellite a “lifeline” for essential services when primary connectivity is lost. That reflects the project partner’s view of the intended use; CableShield’s practical reach will depend on the capacity and capabilities validated during development and trials.
