The end of the optical fibre dropped into her toilet bowl.

It is not the purpose here to explain exactly how an optical fibre works in terms of total internal reflection.

Using optical fibres instead of copper wire has several advantages.

You will also need a length of optical fibre.

The system may be checked without using the optical fibre for the moment.

Sometimes the light is carried to and from the point of observation by optical fibres.

This principle is similar to long distance transmission of light in an optical fibre.

The comparable figure, it said, for optical fibres was nearly £2000.

But the balance may change as optical fibres become cheaper with mass production.

There is much talk of potential bandwidth in optical fibres.
