Minimizing signal interference is crucial to maintain the integrity and efficiency of these networks. Fiber optics play a pivotal role in modern communication systems by providing unparalleled bandwidth, security, and resistance to electromagnetic interference. In the ever-evolving landscape of dense urban environments, the demand for high-speed, reliable communication networks has never been greater. Material Absorption : The glass or plastic core of the fiber. Electromagnetic interference (EMI) can severely affect copper cabling systems, causing noise, errors, and network instability.
