Fibre optic

Let me throw some more light on the term 'fibre optic' to underline the importance of these two very important words, which have brought about a revolutionary change in mass communication over the last ten years. We want people to understand how these two meaningful words, which they must have heard on a number of occasions, are making a big difference in overall growth of IT Industry in this country as well.

The general cabling system is based upon the usage of copper wire to send electrical signals which at last turn into a meaning characterised information or voice or into a pictorial representation of a character disguising into a video clip. We know that the speed of an electrical signal is limited by the speed that a wave can attain in a second whereas a ray of light travels at the speed of 1,86,300(approx.) miles per second. The fibre optic uses a glimpse of light to signal one bit of information (A bit is the smallest unit that the data can be measured in).

Oddly enough, telephone companies like fibre for different reasons: it is thin and lightweight. Many existing cable ducts are completely full, so there is no room to add new capacity. Removing all the copper and replacing it by fibres empties up the ducts. Also fibre is lighter than copper. Thus, induction of fibre optic in our system is surely going to make a big difference and, therefore, we should collectively request our concerned authorities to make a little bit extra effort, if needed, to make this fruitful changes in our system, making sure also that our nation-wide internal system properly connects to submarine cable, which is again fibre optic that connects to the whole world across the globe.

Consequently, a new era of development will commence in Bangladesh.
