👉 The telecom fluid, also known as fiber optic cable or optical fiber, is a specialized type of cable used extensively in telecommunications to transmit data as light signals over long distances. Composed primarily of ultra-pure glass or plastic fibers, these cables enable high-speed internet, voice calls, and video streaming with minimal signal loss. The fluid's core is designed to guide light through the core via total internal reflection, while its cladding layer helps confine the light within the core. This technology supports the backbone of modern communication networks, providing unparalleled bandwidth and reliability for data transmission.
