Submarine network testing

Test with certainty. Act with confidence.

Submarine networks operate under extreme constraints (such as limited access once deployed, ultra-long spans, and costly offshore operations), leaving no room for uncertainty. With approximately 200 cable faults each year and only about 25 dedicated repair vessels worldwide, repair costs can reach up to $1 million per day. This is why getting fast and trusted information quickly 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.

Operate with confidence in the field

Rugged, portable solutions for landing stations and offshore operations—where there’s no second chance.

Why partner with EXFO?

End-to-end credibility across the lifecycle

EXFO supports testing from research and manufacturing to field deployment, landing-station characterization, maintenance, and upgrades.

Comprehensive solution for optical testing requirements

Characterize fiber, monitor network health, localize physical and transmission faults across amplified submarine links.

Rugged portable and rackmount testers for reliable execution

Support automated landing-station workflows or portable offshore and repair-vessel operations.

Confidence from fiber to 400G/800G+

EXFO helps crews validate optical performance—including coherent technologies (100ZR to 800ZR)—to support the transition to higher capacity.

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

Locate faults in just 3 minutes per fiber pair across amplified submarine links up to 20,000 km.

Repair validation before vessel departure

Confirm repair completion and restored performance within minutes before the vessel leaves the site.

Capacity upgrades

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