What is underwater cables?

Underwater cables, also known as submarine cables or undersea cables, we laid them on the seabed to carry telecommunication signals across long distances between continents and countries. We used these cables for intercontinental and international communication, including internet connectivity, telephone calls, and data transmission.

Underwater cables are typically made up of several pairs of optical fibers wrapped in protective layers, including polymers, steel, and other materials. These layers provide insulation and protection against external factors such as water pressure, marine animals, and ship anchoring. The cables are buried in the seabed or secured to it to prevent damage.

These cables are crucial for global communications, as they enable the transfer of massive amounts of data across continents, facilitating international trade, information sharing, and global connectivity. They play a vital role in supporting the internet and telecommunication systems that we rely on in our daily lives.

What type of cable is underwater?

The most common type of cable used for underwater communication is fiber optic cable. Fiber optic cables transmit data through pulses of light that travel along the length of the cable’s glass or plastic fibers. This technology allows for the rapid and efficient transmission of large amounts of data over long distances.

Fiber optic cables have numerous advantages for underwater applications. They have a very high bandwidth capacity, which means they can transmit large volumes of data at high speeds. They are also immune to electromagnetic interference, which can be a problem in other types of cables. Additionally, fiber optic cables are lightweight and flexible, making them easier to deploy and maintain in underwater environments.

While fiber optic cables are the primary type of cable used underwater, there are also some hybrid cables that combine both fiber optics and copper conductors. These hybrid cables provide additional power transmission capabilities along with data transmission.

Overall, the use of fiber optic cables has revolutionized underwater communication, enabling faster and more efficient data transmission across the world’s oceans.https://www.bofan-cable.com/product-category/underwater-cable/
