Submarine network testing

Test with certainty. Act with confidence.

Submarine networks are undergoing a major investment cycle. New cable systems are being deployed, upgraded and replaced, raising the stakes for every decision. These networks operate under extreme constraints, including limited access once deployed, ultra-long spans, and costly offshore operations, leaving no room for uncertainty.

In submarine environments, uncertainty is costly and confidence is critical. EXFO turns optical measurements into decisions you can trust. Our expertise and solutions help crews to reduce risk, avoid costly mistakes, accelerate decision-making and protect uptime.

Applications

Design and manufacturing validation

Validate components, fiber performance and optical characteristics before deployment.

Cable deployment and commissioning

Confirm link integrity, loss, reflectance and optical performance before traffic goes live.

Landing-station characterization

Test the physical and transmission layers at the critical interface between wet plant, dry plant and terrestrial networks.

Maintenance and fault localization

Use OTDR and monitoring capabilities to detect, locate and diagnose issues with precision.

Repair validation before vessel departure

Confirm the repair is complete and performance is restored before the vessel leaves the site.

Capacity upgrades

Validate optical performance and coherent readiness for 100G to 800G+ network evolution.
