We bend optical fibre 90 degrees (or loop it for a full 360!) all the time. The question is about RATE OF BEND, not ANGLE OF BEND. The attenuation increases with decreasing radius.
Coax has served a multitude of purposes over the years, including television signal transmission, computer data buses, and telephone trunk lines. These days, coax is heavily utilized in multi-tenant buildings and is frequently used for internet connections.
Before installation, cable might become spoiled by a leaking warehouse roof or even high humidity if the ends are not sealed and capped. Furthermore, oxidation damage to the braid can extend several inches, or even feet, beneath the jacket from the free end of a detached cable if it is left exposed. This could lead to a bad connection.
When there are only a few places where a cable touches, we advise loosely coiling or folding the cable. The cable should not be wound tightly or around anything.
Compared to flexible coaxial cable assemblies that employ a braided outer conductor, semi-rigid cable assemblies are constructed from premium materials and have the best possible electrical stability.

BNC cabling has been the industry standard for a longer period of time when compared to PoE. While coaxial BNC camera wire does transmit power, it is insufficient to operate the camera on its own, unlike PoE cable. This is a reason why PoE cameras and cables are evolving into the new industry norm.
Flexible cables are obviously useful for the final connection to equipment in fixed installations that may need to be modified, like motors or floodlights. Another option for overhead wiring between buildings is to use flexible cables.
Compared to aluminum, copper is more readily accessible as a stranded conductor, and because the strands can have substantially smaller diameters, the cable is more flexible.
Because [fatter] wires have thicker insulation/jacketing and larger gauge widths, which enable more current to flow through the conductor safely, they have higher ampacity. Larger conductors and better insulation keep everything operating safely in high-power installations.
