Optic Fibre
What is optic fibre?
A technology that uses glass or plastic fibers (threads) to transmit data. It is capable of transmitting messages modulated onto light waves.

- Entry level fibre optic speed starts at 15 Mbps. For example, this means a 5 megabyte film will upload in 8 seconds, and a 10 megabyte film can upload in 16 seconds; or downloading 10 songs would take less than half a minute. This type of speed is typically 3 Mbps faster than the regular cable internet service
- Now with technology rapidly improving, the fastest fibre optic speed has approached around 100 Mbps.
- Modern fibre cables can contain up to a thousand fibres in a single cable, with bandwidth potentially in terabytes per second.
- Some companies are offering unlimited fibre optic broadband for around $300 a month with 100 Mbps speed…
- Fibre optics are known to be the most secure transmission media around as it uses light to transmit data rather than electricity currents.
- The reasons for its high security include:
- that it’s immune to electronic interference,
- it never loses signal
- it can not be tapped into unless a person intercepts the cable physically.
- A security issue relevant to fibre optics include fiber tapping- this is when the network is tapped into and signal is extracted from an optical fibre.
