How brittle are fiber cables?
Solution 1:
Pretty much don't bend them past 90 degrees under load, pinch them, step on them, or crush them. Fiber has a minimum bending radius and varies between fiber manufactures (check out their documentation on the specific fiber). Fiber has a lower tolerance to pulling tension so you should generally pull it by hand, steadily, and not jerky. For the final install keep the tensile load low. While they are not as tolerant to abuse as a cat5 cable, they are actually fairly resistant to abuse.
