High-temperature low loss optical fibers

Keywords:

S.M. Popov


The aim of the work is a researching additional optical loss of copper alloy coated optical fibers which were drawn from low hydroxyl group contamination preforms at temperatures up to 800 °C. It is reached that metal coated optical fiber worked at temperature 700 °C for 7 hours, while the optical losses changed from 2 to 3 dB/km at the wavelength of λ = 1300 nm.
