Which type of cable utilizes light signals for high-speed transmission?

Fiber optic cable utilizes light signals for high-speed transmission, which is a key characteristic that distinguishes it from other types of cabling. Unlike twisted pair cables, which use electrical signals and are suitable for lower bandwidth applications like standard networking, fiber optic cables transmit data by sending pulses of light through strands of glass or plastic. This method allows for significantly greater data rates and extended transmission distances without degradation of signal quality, making fiber optic the preferred choice for high-speed internet and telecommunications infrastructures.

The use of light signals in fiber optic technology results in lower interference and enables the transmission of data over much longer distances compared to copper-based cables like twisted pair or coaxial cables. This quality is particularly valuable in environments that require the transfer of large amounts of data quickly, such as data centers or long-haul communication links.

This distinction is crucial for understanding modern networking since fiber optic technology plays a vital role in supporting the ever-increasing demand for high-speed internet and data services.
