What is a fiber optic cable called

A fiber optic cable is also called an optical-fiber cable.

A fiber optic cable, or optical-fiber cable, is a type of cable that contains one or more optical fibers used to transmit data as pulses of light rather than electrical signals, allowing for high-speed and long-distance communication . The cable typically consists of three main layers: the core, where light travels; the cladding, which surrounds the core and reflects light back into it via total internal reflection; and a buffer coating that protects the fiber from physical damage and moisture . Fiber optic cables come in different types, primarily single-mode and multi-mode. Single-mode cables have a very narrow core, allowing only one light path, which is ideal for long-distance telecommunications. Multi-mode cables have a wider core, supporting multiple light paths, suitable for shorter distances . The fibers are often bundled together and protected by additional layers, including strength members like Kevlar and an outer jacket, to ensure durability in various environments . Fiber optic cables are widely used in internet and broadband networks, telecommunications, networking, and even medical or industrial applications due to their high bandwidth, low signal loss, and immunity to electromagnetic interference . In summary, a fiber optic cable is commonly referred to as an optical-fiber cable, and it functions as a high-speed, light-based data transmission medium with multiple protective layers for durability and performance.
