How to solve this main key problem?
Try fiber optics patchcords that has metal flexible tube to protect against nasty rodents. It is just like ordinary fiber optics patchcords but the fiber optics is being installed into metal flexible conduit and coated with PVC.
The flexible metal conduit will give extra protection for the fiber optics but at the same time will protect the fiber optics against being chewed by rodents.
This is how end products look like.
There is no doubt on the extra bending radius but it does serve the main purpose to protect fiber optics against rodents inside buildings.
