Standards for direct-buried optical cable lightning protection wires

Home / Standards for direct-buried optical cable lightning protection wires

101 describes characteristics, construction and test methods of optical fibre cables for buried application. The Lightning Protection Institute is a nationwide not-for-profit organization founded in 1955 to promote lightning protection education, awareness, and safety. The lightning protection industry began in the United States when Benjamin Franklin postulated that lightning was electricity, and a metal.
