What is Diamond fibre?
It is extracted from the inner coats of the hardy little mountain goats (capra hircus) locally called “Chyangra”, which live at the altitude above 3000 mtrs in the Himalayas. Such wonderful and gossamer properties of “Pashmina” have popularized it as the “Diamond Fibre”.
How is optical fibre made?
An optical fiber (or fibre in British English) is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers typically include a core surrounded by a transparent cladding material with a lower index of refraction.

What is pashmina from where do you get this Fibre?
Pashmina refers to a fine variant of spun cashmere, the animal-hair fibre forming the downy undercoat of the Changthangi goat. The word pashm means “wool” in Persian, but in Kashmir, pashm referred to the raw unspun wool of domesticated Changthangi goats.
Will fibre become obsolete?
While full-fibre connections can currently promise speeds of one gigabit per second, future upgrades could potentially offer speeds in terabits per second. If, come 2030, there is a new emerging technology and countries are thinking about replacing their full-fibre systems, the UK would start on the same footing.
What materials make up fiber optics?
Polymer optical fibres are usually made from a polymethyl methacrylate (PMMA, acrylic) core, surrounded by a cladding made from fluorinated polymer. The cladding material must be of lower refractive index than the core – in other words, light must travel slower through the core material than the cladding.
Who invented fiber optics?
Charles Kuen Kao is known as the “father of fiber optic communications” for his discovery in the 1960s of certain physical properties of glass, which laid the groundwork for high-speed data communication in the Information Age.
