Fibre optics are fast internet cable,that carryes digital information over long distances,It is like a high speed data transfer cable. Inside a fibre optic cable is a glass thread that is thin as human hair. Also fiber optics also provides added security
How does fiber optics work
Fiber optics works by light travelling down the fiber optic cable and it bounces repeatedly of the walls. Fiber optics cabling is based on the optical fiber,which are long, hair width strands of ultra-pure glass. In order for optical fibers to transmit data over long distances, they need to be highly reflective. In order for the finished cable to transmit data signals, it needs to be connected to the two other main components of a fiber-optic system. The first of these is the optical transmitter, a device which converts electrical and analog signals into either On-Off or Linear modulating light signals, then releases that data into the fiber optic cable. Fiber optic cabling has advantages over standard copper coaxial cables, Fiber optic cables can transmit larger quantities of data with far less loss, it is able to maintain signals over long distances and is virtually free from interference, so you won't get any problems from interference. So that's why fiber optics is fastest,more reliable internet cable in the world for many years to come.
