- [Instructor] Troubleshooting fiber optics…doesn't have to be intimidating.…Even without complicated and expensive tools,…I can generally figure out where an issue lies.…Much like troubleshooting copper connections,…it can be quite efficient time-wise to find the end point…and eliminate it as a source of the failure.…When a new connection refuses to come up,…the first step is to ensure…the wrong media type wasn't used.…I will ensure optics on all side are both…multimode or single mode, and all of the cables…used are single mode or multimode.…
