Standard bending radius of optical cable entering the equipment room
The normal recommendation for fiber optic cable is the minimum bend radius under tension during pulling is 20 times the diameter of the cable (d). Proper bend radius control ensures the integrity of optical performance and protects the glass. For example when a cable is bent around a corner, bend radius may be appropriate, but if the cable is used with pulleys or capstans during pulling, then left stored in loops, the diameter of the pulley, capstan or storage loop may be more descriptive. Thus we will define and use both terms. Ignoring these rules leads to improper installation, signal loss, and costly cable damage.

Fiber optic cables must be grounded before entering the equipment room
Conductive fiber optic cable containing metallic components or strength members capable of transmitting stray current must be grounded when entering or terminating on the outside of buildings in compliance with 770. Alternatively, an insulating joint or equivalent device must. Fiber optic cable transmits data as light through glass or plastic strands, which means the fiber core itself carries no electrical current and requires no grounding. For electrical safety, all conductive parts of the system, including hardware, must be properly grounded and bonded. In installations where an optical fiber cable is exposed to contact with electric light or power conductors and the cable enters the building, the. While nonarmored fiber optic cables don't require grounding due to their nonconductive properties, grounding is crucial when using armored fiber optic cables. All fiber optic cables should be marked.
