What common installation hazard can occur if static electricity builds up on a fiber-optic cable?

Static electricity buildup on a fiber-optic cable can indeed lead to electric shock to personnel. While fiber-optic cables themselves do not carry electrical current in the way that copper cables do, they can still accumulate static electricity. When an individual comes into contact with a charged fiber-optic cable, there's a risk that the accumulated static charge can discharge unexpectedly, potentially resulting in an electric shock.

This is particularly pertinent in environments where personnel are handling the cables and conducting installations or maintenance. Ensuring that static electricity is managed properly, for instance by using appropriate grounding techniques and antistatic measures, is essential to minimize safety risks in handling fiber-optic installations.

The other options, while they may relate to fiber-optic cables in broader contexts (such as increased attenuation, fire hazards, or signal loss), do not directly associate with the immediate hazard of static electricity buildup.
