Optical fibers transmit data using light signals, offering significantly higher bandwidth and speed compared to traditional copper cables like coaxial and twisted-pair cables, or wireless methods like infrared rays which are typically limited to short distances and lower speeds for general networking.
– Transmission media speed varies greatly depending on technology.
– Optical fiber is the fastest among the options listed for data communication over distance.
Typical speeds range from Mbps for older twisted pair/coaxial to Gbps and even Tbps for optical fiber. Infrared is primarily used for very short-range communication like remote controls or device-to-device data transfer over a few meters.
