The last breakthrough in this technology welcomed the ADSL broadband internet connection, a million miles away from the original dial-up speed. Now fibre-optic broadband is about to make the same leap.
So how does it work?
The way it works is simply by sending information through pulses of light through individual optical fibres. Each fibre features a number of different elements which allows it to do this. For example, a strand of fibre contains a core, cladding and buffer. The core is the central part of the fibre optical cable made of silica glass and carries the light signal.
Then there is the cladding, which is also made of silica glass and surrounds and reflects light back into the fibre core. The outer layer is the buffer which is typically made of plastic and gives the core and cladding some physical protection.
Fibre optics has less interference than copper wires which were used for ADSL, making them able to transmit data with a stronger signal over greater distances. In addition, fibre optic broadband can also operate at a higher frequency, resulting in a bigger bandwidth. In turn, a greater bandwidth means a faster connection speed which allows users to have high-speed internet.
Not only could households and business have faster internet, but one of the many benefits of fibre optic broadband is that multiple users can be on the same line at the same time without speeds noticeably slowing.
