• Use an optical power meter and light source for checking the fiber optic cables
• Make sure the environment is clean while connecting/splicing fiber optic cables
• All fiber optic connectors should be cleaned prior to connecting to the system
• Fiber connector protective caps should be installed on all non-terminated fibers and removed just before they are
terminated.
