Which one among the following is the fastest mode of transmission media?

Optical fibers are the fastest mode of transmission media among the options provided. They use light pulses to transmit data through glass or plastic strands, allowing for extremely high bandwidth and data transfer rates that can reach several Terabits per second (Tbps).

• Optical fibers: Use light signals, offering the highest speed, lowest latency, and minimal interference over long distances.
• Coaxial cables: Use electrical signals over copper; while faster than basic twisted-pair, they are limited compared to fiber.
• Twisted-pair cables: Commonly used in Ethernet (e.g., Cat6), they support speeds up to 10 Gbps but suffer from signal degradation over distance.
• Infrared rays: A wireless medium requiring line-of-sight, generally used for short-range communication with much lower data rates.
