Fibre: What is fibre multiplexing?
Fibre multiplexing is a technique used to transmit multiple streams of data over a single fiber optic cable. This allows for a large amount of data to be transmitted efficiently and quickly.
Imagine you have a bunch of different colored pencils, and you want to send them all to your friend who lives far away. One way to do this would be to pack each pencil into a separate box and send it through the mail. This would work, but it would take a lot of time and be expensive to send all those boxes.
Instead, you could put all the pencils into one big box and send them all at once. This is like what fibre multiplexing does with data. Instead of sending each piece of data separately, fibre multiplexing combines many different pieces of data into one big bundle and sends them all together through a fiber optic cable. This way, you can send a lot of data very quickly and efficiently.
There are several different methods of fibre multiplexing, including time-division multiplexing (TDM), wavelength-division multiplexing (WDM), and dense wavelength-division multiplexing (DWDM). These methods differ in how they combine the multiple streams of data, but the basic concept is the same: using a single fiber optic cable to transmit multiple streams of data simultaneously.
Fibre multiplexing is used in a variety of applications, including telecommunications, internet service providers, and cable TV. It is an important technology that allows us to transmit large amounts of data over long distances quickly and efficiently.
