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.
