Morphology
The meaning 'a bundle of fibers' is directly and transparently derived from combining 'fiber' (threadlike cell) with 'bundle' (group of things packaged together); this is a straightforward compound noun. Even though it can be used in technical contexts (e.g., nerve fiber bundles), the relation is fully compositional and thus accessible to a B1 learner who knows both constituents.
Etymology
Fiber bundle paints a simple picture: many thin fibers tied together into a bundle, like threads in a rope or nerve cells grouped in a cord. So it means 'a group of fibers', often groups of nerve fibers that run together in the body.
