Grounding Requirements for Outdoor Optical Cables

Industry standards such as the NEC (National Electrical Code) Article 770 and NFPA 70 provide binding requirements, while standards from IEEE and TIA offer additional guidance. Many fiber optic cables include metallic components — such as steel armoring, aluminum moisture barriers, copper strength members, or metallic messenger wires — that absolutely must be grounded to prevent electric shock, equipment damage, and fire hazards. In contrast, fully dielectric cables with. The Fiber Optic Association, Inc. (FOA) was founded in 1995 to help develop the workforce to build the fiber optic networks to support a rapid expansion in communications and the Internet. The charter of the FOA was to promote professionalism in fiber optics through education, certification, and. Where reels are supplied with protective material fitted over the cable, the protection should remain in place until the cable will be installed. During installation, all curvatures should be smooth. Turn-backs and all sharp changes of direction. Plan your outdoor fiber installation carefully by surveying the site, choosing the right cable type, and following FOA and OSP standards to ensure reliability. Use. Installing on poles can be quick and cost effective, but rights-of-way can be difficult to obtain. Cable is suspended between poles or lashed onto a separate aerial messenger wire.
