Category of Submarine communications cable

The types of Submarine communications cable can be divided into the following three aspects:

1. Number of conductive cores. It is mainly divided into three core submarine cables and single core submarine cables, with the majority of medium and low voltage lines using three core submarine cables and high voltage lines using single core submarine cables.

2. Transmission function. Traditional submarine cables only have a simple power transmission function, while new submarine cables belong to optoelectronic composite cables, effectively achieving the transmission of electrical energy and signals on the same cable line.

3. Load type. Divided into DC submarine cables and AC submarine cables, DC submarine cables are characterized by low losses and easy to achieve long-distance transmission. However, the application experience of DC submarine cables is not rich, and the construction cost of DC converter stations and other supporting facilities is high. AC submarine cables have high losses, but the operation and maintenance technology is mature and the supporting construction cost is small. Therefore, submarine cable line designers usually need to balance technology and economy to achieve maximum benefits.

Impact of Submarine communications cable

The impact of Submarine communications cable cannot be overemphasized. They have completely changed our way of communication and achieved instant global connectivity. They also promote international business, research, and cultural exchange. Without Submarine communications cable, our world would be very different.

However, the Submarine communications cable is not without controversy. Some countries are concerned about the safety of these cables as they are easily damaged or intercepted. Others question the environmental impact of laying and maintaining these cables, as well as the potential damage to marine life.

The Submarine communications cable can be considered as an invisible highway in our digital era. They are crucial to the operation of our global economy and society, but they are hidden. They connect us to each other, but they also create differences and inequalities. For example, some countries have easier access to Submarine communications cable than others, leading to a digital divide.

Compared with the ubiquitous Submarine communications cable, their history and technology are relatively unknown to the public. I take the speed and reliability of internet connections for granted, but I am not aware of the enormous effort and resources required to maintain this infrastructure. The Submarine communications cable reminds us that we still know very little about the technology that shapes our world.
