Fibre Optics


Optical fibre cable is treated with deuterium gas at the final step of fibre optics manufacturing. For some fibres there is a significant risk that the optical properties could deteriorate due to the chemical reactions with the atoms in or around the cables. Deuterium replaces some of the protium on the fibre cables, which reduces the chemical reaction rate leading to deterioration of the light transmission and extends the life of the cable.
