Endless Knowledge - Facts & News on Instagram: "Optical fibres work by trapping light inside an ultra-pure glass strand. The core carries light, while the surrounding cladding has a different density that causes total internal reflection—keeping the light bouncing inside even when the cable bends. A laser or LED sends rapid on-off pulses that represent binary data, and a detector converts them back into information. Because light travels fast and glass loses very little energy, huge amounts of d
