Underwater internet cables are being laid continuously on the ocean floor for the past few decades. Ocean fiber optic cables have been one of the most prominent and iconic usages of fiber optics for communicating over vast distances.

is what makes undersea internet cables an attractive solution for telecoms, businesses, and governments to conduct their operations from continent to continent without any disruptions.


Maximum continuous length:

50 km


Fiber optic sensing has also become an attractive new opportunity in recent subsea cable projects. For example, in oil & gas drilling in open waters, fiber optic sensing technology can provide valuable metrics for the drilling operations under kilometers of water, rock, and soil.

Why Fiber Optics

Long Lifetime

Almost no maintenance over the whole lifetime.

Passive Sensor

No electrical power at the measurement point needed if used as a sensor.

Long Distance

Monitoring (50 km and more) of remote locations and objects, if used as a sensor.

Resists High Pressures and High Temperatures

Resists extreme temperatures from -269 to 700+ degrees

For Harsh and Explosive Environments

Resistant to corrosion, lightning, etc.

Immune to EMI

Electromagnetic interference
