Fiber optic cables are network cables that contain glass fiber strands within an insulated casing, designed for high-performance, long-distance data networking and telecommunications. These cables provide higher bandwidth and transmit data over longer distances compared to more common cables. Fiber technology has transformed telecommunications and connectivity, enabling signals to be sent all over the world at the speed of light.

A fiber optic cable consists of one or more glass strands, each slightly thicker than a human hair. The center of each strand is called the core, which provides the path for light to travel. The core is surrounded by a glass layer called cladding that reflects light inward to prevent signal loss and allow light to pass through the cable's bends. The two main types of fiber optic cables are single-mode and multi-mode. Single-mode fiber uses extremely thin glass strands and a laser to generate light, while multi-mode fiber optic cables use LEDs.

Fiber optic cables offer several advantages over long-distance copper cabling. For example, fiber optics supports higher capacity, as the amount of network bandwidth a fiber cable can carry easily exceeds that of a copper cable of similar thickness. 10 Gbps, 40 Gbps, and 100 Gbps fiber cables are standard. In addition, light can travel much longer distances through a fiber cable without losing its strength, reducing the need for signal amplifiers. Fiber optic cables are also less susceptible to electromagnetic interference.

Fiber optic cables are used in a wide range of applications, from telecommunications to computer networks. There are different types of fiber optic cables, such as single-mode and multi-mode fiber optic cables, and they are also classified according to their mode type and transmission speed. In addition, flame-retardant designs (IEC 60331) are available for all cable construction types, upon request.

In summary, fiber optic cables are a key technology in telecommunications and connectivity, offering significant advantages in terms of capacity, distance, and resistance to interference.
