More recently, there were cables that allow for a bend with a radius of up to 5mm ( such cables are normalized standard ITU G. 657 ). Bend before something can be, but with fatal consequences (and worst fiber broken, at best, greatly increased attenuation). Now bend at 5mm contribute no more than 0.1 dB.
Moreover, manufacturers of cables advertise that in the presence of 150 bends 90 degrees to the minimum permissible radius of 500 and secured by conventional metal braces without pads does not make more than 0.1 dB attenuation. Most is for razvodok buildings and apartments for FTTH solutions.
And the most important fact for those who understand how easy it is to mount the cable. stapler.
