Getting Started Before you get started, please read this list of do's and don'ts. Throughout the course, we'll be offering hints on safety, tools and test equipment, procedures, and "tricks of the trade" that can make testing easier and more accurate. |
1. Read the directions thoroughly before starting 2. Clean connectors carefully (dirt is harmful to connectors and causes loss which affects measurements). Use lint-free pads and pure isopropyl alcohol.  3. Handle cables carefully (fiber is very stong but can be broken by mishandling, especially near the connector) 4. Handle connectors gently 5. Use a fiber optic power meter to detect the presence of light |

Eye Safety Most fiber optic systems have very low power levels - much too low to harm your eyes. However, some CATV and telco WDM systems do have power levels that can be harmful. If you are working on a installation, there should be no network equipment connected that could be dangerous, but someone could be using an OTDR on the cables. Always use a power meter to check for power in the fiber before inspection with a microscope anytime! Remember looking into a fiber is silly - systems use infrared light which you can't see anyway!
