Question: 1 / 400

What can excessive bending in fiber optic cables lead to?

Increased bandwidth

Potential breakage or signal loss

Excessive bending in fiber optic cables can lead to potential breakage or signal loss due to the physical stress placed on the fibers. Fiber optic cables are designed to transmit light efficiently, but if they are bent too tightly, it can cause the light signals to leak out of the fiber core, leading to diminished performance and signal degradation. The integrity of the optical fibers relies on maintaining a certain bend radius; when this radius is exceeded, the structural integrity is compromised. This can result in a break in the fiber or an increase in attenuation, which is the reduction of signal strength. Proper installation and handling are crucial to prevent these issues and ensure reliable performance of the fiber optic system.
