Why is it crucial to avoid electrical conductivity in materials used for nonconductive optical fiber cables?

Avoiding electrical conductivity in materials used for nonconductive optical fiber cables is crucial primarily to prevent electrical shock hazards. Optical fibers are designed to transmit light signals rather than electrical signals, and if the materials used in the cable were conductive, they could carry electrical currents. This presents a significant safety risk, as anyone handling the cable might be exposed to electrical shock if a fault occurs.

Moreover, in environments where electrical hazards are a concern, using nonconductive materials enhances safety by ensuring that the fibers do not inadvertently conduct electricity. This is particularly important in installations near power sources or in wet or conductive environments where the risk of electrical interference and shock is heightened. Thus, the focus on maintaining nonconductivity significantly contributes to the overall safety of both personnel and equipment.
