Does the vibrating fiber optic cable have an electric current

Fiber optic cables, including vibrating ones, do not carry an electric current; they transmit data using light. Fiber optic cables are made of glass or plastic fibers that transmit information as pulses of light rather than electrical signals, so the cable itself does not conduct electricity or require an electric current to function. The light travels through the core of the fiber, reflecting internally due to the cladding, allowing data to move over long distances without electrical conduction.

Vibrations or physical movement of the cable do not change this property; the fiber still only carries light. However, the components that generate and detect the light—such as lasers, LEDs, transmitters, receivers, and amplifiers—do require electricity to operate. These devices convert electrical signals into light pulses and back into electrical signals for your devices.

Therefore, while the fiber itself remains non-electrical, the overall fiber optic system depends on electrical power to function. In summary, a vibrating fiber optic cable does not have an electric current running through it, but the system supporting it relies on electricity to generate, transmit, and receive the light signals. This makes fiber optics immune to electromagnetic interference and safe to use near electrical equipment, even when physically moving or vibrating.
