What safety measure should be taken when working with fiber optic cables?

When working with fiber optic cables, using protective eyewear for laser safety is crucial. This is because fiber optic communication systems frequently employ lasers to transmit data over long distances. These lasers, while efficient, can be harmful if viewed directly, as they emit concentrated beams of light that can cause serious eye damage. Protective eyewear is specifically designed to filter out dangerous wavelengths, thereby safeguarding the technician's eyes while they are working with the cables.

In contrast, while wearing gloves, avoiding contact with water, and working only during daylight hours may contribute to a safer work environment in specific contexts, they do not address the inherent risks posed by the lasers used in fiber optics. Water contact can potentially disrupt electrical equipment or cause short circuits, and daylight does not mitigate the risk associated with laser exposure. Thus, among the options, prioritizing laser safety with protective eyewear is a necessity for anyone engaged in installing or handling fiber optic cables.
