Fiber optic cables offer high data transmission speeds and bandwidth capabilities, making them superior for modern communication systems. They transmit data as light pulses through thin strands of glass or plastic fibers, allowing for faster and more efficient data transfer compared to traditional copper cables. Fiber optics also provide advantages like immunity to electromagnetic interference, longer transmission distances without signal loss, and enhanced security for data transmission. These benefits make fiber optics the preferred choice for high-speed internet, telecommunications, and data networks.
