For Unshielded cables, it will 8 multiplies cable diameter and for shielded cables, it is 12 multiplies the cable diameter. However, the smaller the bend radius, the greater is the material flexibility.

Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.
4 times the diameter of the cable
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
you double the radius to find the diameter.
You already know the radius.
The transmission is unreliable after the bend radius is exceeded.
5d bend
The RADIUS of a 5D pipe bend is actually what is 5 times the nominal diameter. So if you had a 10" diameter pipe, the radius of the centerline of the bend would be 50 inches.
A 3D bend is a pipe bend that the bend radius is 3 times the pipe outside diameter.

The radius of the curve of the inner edge of the bends shall be at least 6 times the external diameter for armoured cable.

Four times the outer jacket diameter.

Use the curvature of a tennis ball as a good guide. Try not to bend fiber cables any more than this. The maximum bend (called the maximum bend radius) for any fibre optic cable is determined by the manufacturer, and improvements are being made all of the time. With todays cables, if you bend a fiber optic cable 90 degrees (so it is shaped like the letter L) you will surely damage it. You want to have smooth, gradual curves, and don't go beyond the radius of a tennis ball.
