[UgaBYTES] Fibre Optic systems made simple

[dmethus at uccmail.co.tz]

Hi All,

To add on what Otieno has mentioned is that with Fibre opric cable many
Telecentres will be able to pay less for the bandwidth. As we are all
aware that currently many countries in Africa depend on satelite and the
cost is very high.

> 5.Light signals – unlike electrical signals in copper wires, light signals
> from one fibre do not interfere with those of other fibres in the same
> cable. This means clearer phone conversations or TV reception.
> 6.Low power – because signals in optical fibres degrade less, lower power
> transmitters can be used instead of high voltage electrical transmitters
> needed for copper wires. Again this saves your provider and you money.
> 7.Digital signals – optical fibres are ideally suited for carrying digital
> information, which is especially useful in computer networks.
> 8.Non-flammable – because no electricity is passed through optical fibres,
> there is no fire hazard.
> 9.Flexible – because fibre optics are so flexible and can transmit and
> receive light, they are used in many flexible digital cameras for the
> following purposes:-
> -    Medical imaging – in bronchoscopes, endoscopes, laparoscopes.
> -    Mechanical imaging – inspecting mechanical welds in pipes and engines
> (in airplanes, rockets, space shuttles, cars)
> -    Plumbing – to inspect sewer lines.
