Fiber optical cable can be used in telecommunications and networks where cabling space is limited. A single fiber takes up much less space and can carry much more data than most electrical cables, such as Category Ethernet cabling.  Fiber Optic cable uses pulses of light instead of an electrical transmission to transmit data at the speed of light.  The light forms an electromagnetic carrier wave that is modulated to carry data information.  Fiber optic cable is not affected by electrical interference from cross-talk between signals or environmental noise pickup.

Since fiber optic cable uses a light based data transmission method instead of an electrical based data transmission method and does not conduct electricity it is an ideal solution for network cabling in high voltage environments.  Fiber optic cable can be used safely in environments where explosive fumes, gases or other explosive elements are present, without being concerned about an ignition being caused by the fiber optic cable.

Fiber optic cable is flexible, but it does have its limitations.  Bending fiber optic cable causes what is known as leaks, which translates to signal loss.  The more you bend a fiber optic cable the more signal loss will occur.  There are specially made bendable fibers for cable installations that require bending around corners or other objects during installation.
