Bend Radius
Cables, especially fibre optic cables, should not be bent too tightly. This is where the bend radius comes in.
The core, or wires, of the cable are flexible, but only to a point. If you bend it too tightly, it could fracture, which will affect the signal passing through.
These cables have a ‘bend radius’. This is how tight this cable can be bent before damage occurs.
The more flexible a material is, the tighter the bend radius can be.
Check with the manufacturer to see what the bend radius is on their cables.
