Free CompTIA Network+ N10-008 Practice Question

During a network performance evaluation, a network administrator observes that the throughput on a single-mode fiber optic link is significantly below expected levels. The link was recently extended to accommodate new infrastructure, which included additional splices and an inline optical attenuator. Which step should the administrator take first to address the suspected low optical link budget?

  • Measure end-to-end signal strength using a light meter to assess whether the signal levels are within acceptable range.

  • Immediately replace the newly extended cable segments with higher-quality cables.

  • Replace the optical attenuator with one that has a higher attenuation rating to reduce potential excess signal strength.

  • Bypass the new splices one at a time to check which splice is causing the most signal degradation.
