When working with fiber optics, what is the recommended action if cable slack is insufficient?

  1. Remove connectors to fit the slack

  2. Add additional fittings

  3. Consult local codes for guidance

  4. Add slack to allow for flexibility

The correct answer is: Add slack to allow for flexibility

In fiber optics installation and maintenance, it is crucial to ensure that there is enough slack in the fiber optic cables to allow for flexibility and to accommodate potential future changes or adjustments. Adding slack helps to prevent stress on the cables, which can cause damage, signal loss, or increased attenuation over time. Adequate slack allows for movement, serviceability, and repair without having to remove or replace entire sections of fiber. By ensuring there is sufficient slack, technicians can make adjustments when needed, such as relocating equipment or replacing connectors without risking damage to the optical fibers. Maintaining proper slack levels contributes significantly to the longevity and reliability of the fiber optic system.
