Submarine cables are the hidden highways of our digital world lying under oceans. They work tirelessly and connect continents and countries. They play an important role in connecting this global village, but how do they connect to the internet? If you are thinking the same, you are in the right place, Here, we will find out how submarine cables connect to the Internet. Let’s explore!
Physical Infrastructure of Submarine Cables
Submarine cables are lengthy fiber optic wires, measuring approximately 25mm in diameter or 1 inch, with weight averaging around 1.4 tonnes per kilometer. These giant cables are spread across the seabed. It uses optical fiber technology to seamlessly transmit the digital data. These cables have robust construction and can withstand harsh ocean conditions. Moreover, they provide effective and fast internet connectivity around the globe. Compared to old copper wires, the speed of fiber optic submarine cables is comparatively better. Laying the submarine cables i+s a really critical process. Ships equipped with specialized machinery carefully lay these cables on the seabed. These cables then connect to the ground stations and connect the oceans and countries. After installation, rigorous speed test are conducted to ensure optimal performance and reliability.
Data Transmission Process
Submarine cables have revolutionized the old data transmission processes and use advanced technology to ensure efficient transmission. Submarine cables carry data using laser pulses along fiber-optic strands. Data travels as the pulse of light dances through the cables. Repeaters boost the signal every 50-100 kilometers to prevent signal loss. This approach enables lightning-fast transmission speeds, ensuring that internet data flows seamlessly across countries and continents. It’s like an information superhighway under the water. Moreover, with the reliable connectivity provided by submarine cables, families can enjoy seamless browsing and streaming experiences with Globe at Home services.
Challenges Faced By Submarine Cables
Although submarine cables have strong construction, they may face a number of challenges underwater. Natural calamities, such as earthquakes and tsunamis, pose substantial risks, potentially damaging or disrupting these critical communication networks and triggering widespread internet outages. Also, human activities like as fishing and ship anchoring might unintentionally damage underwater cables, risking their integrity. As a result, frequent maintenance and attentive monitoring are required to ensure the continuous reliability and operation of these critical infrastructures, maintaining uninterrupted internet access for consumers worldwide. Repairing the submarine cables is not really simple. It is a complex process that requires deep-sea acrobatics and also costs a sufficient amount.
