Researchers in the second week of March 2012 used fibre-optic technology, under a project called Sardana to run ultra-fast Internet. It demonstrated speed of upto 10 Gigabits per second (Gbps), around 2000 times faster than today’s fastest Internet speed. The research showed that by using existing fibre infrastructure Internet’s speed could be increased.
Within next three years, yearly global internet traffic will be measured in Zettabytes(one trillion Gigabytes), which is a four-fold increase from today. You Tube and Netflix will have most of the traffic.
It is is a method of transmitting information from one place to another by sending pulses of light through an optical fibe which is a flexible fiber made of silica which employes the principle of Total Internal Reflection to transmit the light pulses from one end to the other.
Total Internal Reflection
It is a phenomenon where light travelling from denser medium (like glass) to rarer medium (like air) will be reflected back into the denser medium if the angle of incidence is more than the critical angle.
