Which type of cable is composed of small strands of glass?

Fiber-optic cable is composed of small strands of glass, which are designed to transmit data as pulses of light. This technology allows for high-speed data transmission over longer distances with minimal loss or interference compared to other cable types. The glass fibers within the cable are capable of carrying large amounts of information, making them ideal for internet connections, telecommunications, and high-definition video transmission.

In contrast, coaxial cable consists of a copper conductor surrounded by insulation and a metal shielding, which is used primarily for cable television and internet services. Twisted pair cable is made up of pairs of insulated copper wires twisted together, commonly used in telecommunications and networking. RCA cable typically refers to a type of electrical connector used for transmitting audio and video signals, composed of a metal conductor and an insulating plastic casing, not glass. Thus, the distinct structure and materials used in fiber-optic cables uniquely enable their performance characteristics.
