Final answer:
Fiber optics is the term for glass fiber that transmits voice or data signals via light pulses. It employs the transmission of light down fibers of plastic or glass using total internal reflection, and offers advantages such as low loss, high bandwidth, and reduced crosstalk.
Step-by-step explanation:
Fiber optics is the term for glass fiber that transmits voice or data signals via light pulses. It employs the transmission of light down fibers of plastic or glass using total internal reflection. Optical fiber communication systems offer several advantages over electrical based systems, particularly for long distances, such as low loss, high bandwidth, and reduced crosstalk.
