Undersea cable networks have formed the backbone of the global communication infrastructure, linking continents and countries. The stability and performance of underwater cable networks are crucial in today’s world, when internet and communication technologies play a significant part in practically every aspect of life. As we explored in the first article of SUBCO’s ten-part series, diversity is one of the most important techniques to improve the stability and performance of underwater cable networks. This article will delve into how, exactly, diversity improves reliability and performance.

Diverse underwater cable networks are the construction of various undersea cable systems that serve the same region and provide multiple and redundant data transmission methods. This method improves the network’s resilience and dependability, as well as its overall performance. In the case of a cable failure, traffic may be rerouted through other cables, limiting network disruption and ensuring that communication services remain available.

One of the most significant benefits of a varied underwater cable network is increased security. Because underwater cables can be physically damaged by ship anchors, earthquakes, and other natural disasters, having numerous cables provides a redundant method for data transfer, lowering the chance of communication failure. This is especially vital for critical services like financial transactions, military communications, and emergency services that demand high levels of dependability and availability. Improved performance is another advantage of a varied underwater cable network. Multiple cables boost the network’s data transmission capacity, allowing for more data to be delivered in less time. This can assist to minimise data latency, or delay, which is especially crucial for time-sensitive applications like online gaming, financial transactions, and high-definition video conferencing.

Additionally, a varied underwater cable network reduces the danger of congestion. As the demand for internet services grows, so does the number of users and the volume of data transferred over the network. With a varied network, data traffic may be distributed across numerous connections, decreasing the danger of congestion and maintaining the network’s ability to meet expanding demand. A varied underwater cable network delivers benefits not just to customers but also to operators. Multiple cables enhance the network’s total redundancy, lowering the chance of network failure and boosting network availability. This minimises the need for costly backup devices and may cut network operational expenses.

In summary, a varied underwater cable network has various advantages, including increased reliability and performance, higher security, lower latency, lower danger of congestion, and lower operational expenses. The necessity of a diversified underwater cable network cannot be emphasised, given the continuing advancement of internet and communication technologies. As the need for data transmission grows, building several underwater cables will become increasingly crucial for assuring the global communication infrastructure’s continuous stability and performance.
