were that the cable had to be fibre optic fire survival

Frank La Rue, the UN Special Rapporteur on Freedom of Expression explained in a recent report that “by placing taps on the HDMI Fibre optic cable, through which the majority of digital communication information flows, and applying word, voice and speech recognition, States can achieve almost complete control of tele- and online communications.”  La Rue states this kind of “[m]ass interception technology eradicates any considerations of proportionality, enabling indiscriminate surveillance. It enables the State to copy and monitor every single act of communication in a particular country or area, without gaining authorisation for each individual case of interception.”Traditional Fibre optic cable propagate light along straight lines, however this new technology focuses of sending beams of light in a donut shape laser light beam called optical vortices which twists like a tornado as it moves Multimode fiber along the fibre optic cable.Optical vortices, also known as Orbital Angular Momentum (OAM) beams are nothing new and have been studied in depth in atomic physics, quantum optics and even molecular biology. OAM beams were thought to be unstable inside a fibre optic cable, however a new research paper published by BU Engineering Professor Siddharth Ramachandran along with USC’s Alan Willner demonstrated that not only could these beams be made stable inside a fibre optic cable but could potentially be used to boost internet bandwidth.
