Everyone by now knows what fibre optic cable is, but do they know how it works and why it’s so much faster than cable or wireless digital broadband?
In the 1980s telephone companies started putting fibre optic cables under the ground instead of copper cable. The benefit was that the media, glass, was much cheaper than metal, could carry vastly more information, and carry it over much greater distances without the need for signal boosters, switches or repeaters. Copper wire had been in use since the days of the telegraph, and it was quite sufficient when it wasn’t common for every home to have a phone, and the only signal that it had to carry was the voices of the two people having a conversation.
With the advent of the micro-computer, the internet and world wide web, the needs of the infrastructure changed, so the phone company started using fibre optics instead of copper. But if you were using a home computer in the 90s once it became more common for a home to have a computer and internet access you might not have seen much in the way of ‘fast internet’ as we understand it today. Your computer will have still been connected to your modem via a copper cable, and that dial-up modem will have been connected to local exchange via metal cable. Hubs and servers all over the world would be connected by fibre optic lines, but there was still so much metal in the system that the full speed potential could never be reached.
That’s changing very rapidly now. The internet is no longer regarded simply as a useful tool, it’s become so much a part of our lives that it is being considered by many to be a utility, just like gas, electricity and water. Consequently, in order to provide the kind of speed people need to make the internet serviceable, notwithstanding however many people are all using it at the same time, it’s necessary to ensure that as many people have access to fibre all the way up to their property, or an equally acceptable alternative.
