However, they are limited in bandwidth, prone to electromagnetic interference, and vulnerable to signal degradation over long distances. In optical fiber systems, crosstalk (also known as optical coupling) occurs when light from one fiber leaks into another fiber, resulting in interference that can degrade the signal quality. They support high-speed, interference-resistant communication and are particularly effective in applications that require high bandwidth, low latency, and strong signal integrity. Minimizing crosstalk is essential for maintaining reliable high. One promising method to increase the bit-rate capacity of optical fibers is the use of Multi-Core Fibers (MCFs). A novel approach is proposed to suppress crosstalk in MCFs.
