Multi-core fibers increase capacity per system, while uncoupling can reduce signaling complexity and interference.

New undersea web cable to connect major Asian information hubs
The Asia Direct Cable Consortium has chosen NEC to build its new high-performance submarine cable. The finished cable will feature multiple pairs of high capacity optical fibers designed to carry more than 140 Tbps of traffic to allow for high capacity transmission of data across the East and Southeast Asian regions. As a result of ADC’s high capacity, the new submarine cable will be able to support bandwidth-intensive applications driven by technological advancements in 5G, the cloud, IoT and AI.
The Weak Point of the Web – Undersea Internet Cables
According to TechRadar, “Around 380 undersea cables carry over 99.5% of all transoceanic data, running for 750,000 miles across the ocean floor. These fiber optic wires connect the massive data centers supporting cloud behemoths such as Amazon Web Services, Microsoft Azure and Google Cloud.” There are over 100 cable breaks per year. In developed countries, these breaks go largely unnoticed because of redundant systems. But in some places, a single fiber cable can supply internet for millions of people.
