Fibre bundle

A fibre bundle is like a group of straws stuck together. Imagine that you have a bunch of straws twisted together. That bundle of straws is now like one straw - it can be bent, picked up and moved. Fibre bundles are like that, except instead of straws, the 'fibres' are made of strands of glass or plastic. The strands are stuck together into a bundle so they can all move together. Fibre bundles are used to send things like data and light signals along long distances very quickly.
