There have been considerable advances in the use of fibre optics.
Only a small fraction of the emitted photons will be accepted by the fibre optics and there is a further attenuation of light in the fibre optics.
A potential disadvantage of tapered fibre optics is that some distortion is usually introduced in the manufacturing process, which involves heating and stretching bundles of fibres.
Some of the requirements such as being able to correct for distortions introduced by tapered fibre optics are exactly the same as for recording electron diffraction patterns.
The optical alignment of fibre optics is much simpler as no focusing is involved.
These use various combinations of acoustic technology, laser technology, fibre optics and applications of advanced micro-electronics.
Fibre optics will be developed only by granting a 25-year franchise to an operator on the condition that he will use the most up-to-date fibre optic technology.
Fibre optics and broad band cable should be developed at the speed and in the way that the market demands.
