Submarine Cable: These specialized cables are manufactured by only a few companies worldwide. These cables are manufactured in high-tech factories where each layer is carefully crafted.

(How is an undersea internet cable made?)

Submarine Cable: Today, we think of the internet as connected to mobile phones or Wi-Fi, but the reality is much more interesting. When you access a website from another country or make a video call with someone abroad, the data travels not through the sky but through the depths of the ocean.

What are undersea cables?

To connect countries around the world, highly specialized cables called undersea cables or submarine cables are laid beneath the seafloor . These cables use fiber optic technology, consisting of extremely thin glass fibers. Through these cables, data is transmitted thousands of kilometers in the form of light signals.

Where are these cables made?

These specialized cables are manufactured by only a select few companies worldwide, including SubCom, Alcatel Submarine Networks, and NEC Corporation. These cables are manufactured in high-tech factories where each layer is meticulously crafted. A cable consists of more than just fiber, but also multiple layers of steel, copper, and insulation to protect it from ocean pressure, water, and external threats.

How are cables laid in the sea?

These cables are laid underwater, not using conventional methods, but using specialized vessels. First, the entire route is surveyed, and then the cable is gradually laid along the seabed. In some places, it is even buried underground to protect it from fishing nets or ship anchors.

Can the internet ever be shut down?

These underwater cables are quite strong, but not completely safe. Sometimes, earthquakes , ship anchors, or even shark bites can damage these cables. However, such incidents are rare, and companies immediately send teams to repair them.

Why are these cables necessary?

You'll be surprised to know that approximately 95% of the world's internet data is transferred via these undersea cables. Satellite internet is also available, but it's not as fast or reliable. These underwater cables are the lifeline of the modern world. Even though we can't see them, our everyday digital lives depend on them.
