Point all fibers away from yourself and others at all times.
Do not look into the ends of fibers, or point fibers at others. Most laser energy is invisible to the
human eye and yet can be at very damaging power levels to the human eye.
Fiber Handling Guidelines
Poor fiber handling practices and bends in the fiber cable cause signal attenuation.
Adhere to the following guidelines for handling fiber-optic cable:
Do not step on or set anything on top of fiber-optic cable
Do not twist fiber-optic cables
Do not pull on fiber-optic cable (pull on strength members only)
Do not pull on connectors
Do not look at connectors and end faces (unless both cable ends are in hand)
Do not look into equipment ports housing lasers
Inspecting Optical Connectors
An important part of the recommended cleaning procedure for optical connectors is
inspecting the end face of the connector.
Optimally, the end face must be clean and free from cracks, scratches, edge chips,
hackles, pits and other anomalies.
Using a fiberscope with at least 200X magnification, inspect the optical connectors
before and after cleaning. Follow the fiberscope manufacturer instructions.
Always turn the lasers off before beginning the inspection.
