Question
How can a bundle of optical fibers be used? Explain.

Answer

Bundles of optical fibers can be used in many ways. Optical fibers are extensively used for transmission and receiving of electrical signals, which are converted into light by suitable transducers. It is clear that optical fibers can also be used for transmitting optical signals. For example, they are used as 'light pipes' for visual observation of internal organs, such as the oesophagus, stomach and intestines.
