Optical fibers have become the foundation of modern data transmission, used for everything from telecoms and internet services to governmental and space applications. This is because they’re capable of transmitting larger amounts of data at faster speeds and over longer distances, compared to other technologies.

The structure of optical fibers, however, can occasionally lead to network failures, as any twisted or bent cables can hinder the information transfer. To address this issue, scientists at the University of Bath in the UK have designed a new type of fiber, aiming to enhance the robustness of these networks.

A regular optical fiber consists of three elements: the core, the cladding, and the coating.

The core is at the center and provides a pathway for light (the medium through which data is transmitted) to travel. The cladding holds the light inside the core and controls the direction in which it travels, bouncing along as though reflecting off a mirror. Finally, the coating works as the primary buffer and a jacket encases the entire structure.
