What kind of materials are not included in nonconductive optical fiber cables?

Nonconductive optical fiber cables are specifically designed to transmit data through light rather than electrical signals, which is why they rely on materials that do not conduct electricity. The inclusion of electrically conductive materials would negate the key defining characteristic of nonconductive optical fiber cables, as these materials would introduce the possibility of electrical current flow, leading to potential issues like signal interference or safety hazards.

Insulating materials, non-metallic materials, and organic materials can exist safely within this type of optical fiber because they do not inherently conduct electricity. Insulating materials serve to protect the fiber and maintain the integrity of the light signal. Non-metallic materials are often used in the construction of the cable itself because they do not conduct electricity. Organic materials, when used, are also typically nonconductive and can be part of the optical fiber's composition without compromising its nonconductive properties. Therefore, the presence of electrically conductive materials is the key factor that makes the answer correct, as they are specifically excluded from the composition of nonconductive optical fiber cables.
