What is the grounding resistance requirement for fiber distribution boxes
The ANSI/TIA-607-B standard covers regulatory requirements, an overview of a bonding and grounding system, the components involved, and design requirements. Bonding and grounding is required for the safe and effective dissipation of unwanted electrical current that may arise in a telecommunications system. Normally, dielectric optical fiber. The ground resistance between all system parts shall be < 0. Alternative 1: From. ication and relevant standards over the range of optical wavelengths from 1260nm to 1625nm. Mounting: The box should have integral mounting features, such as slots or threaded holes, to enable. In installations where an optical fiber cable is exposed to contact with electric light or power conductors and the cable enters the building, the non–current-carrying metallic members shall be either grounded as specified in 770. 100, or interrupted by an insulating joint or equivalent device.
