Estimating the term…
The invention relates to microstructured optical fibers that are drawn through hollow channels and have a core region, which extends along a fiber longitudinal axis, and a jacket region surrounding the core region. The aim of the invention is to reduce a damping increase due to corrosion and to reduce the emission of chlorine on the basis of the microstructured optical fibers. This is achieved in that at least some of the hollow channels are delimited by a wall material made of synthetic quartz glass which has a chlorine concentration of less than 300 wt. ppm and oxygen deficiency centers in a concentration of at least 2×1015 cm-3.
A microstructured optical fiber which has a core region extending along a longitudinal axis of the microstructured optical fiber and an inner cladding region surrounding the core region, and through which hollow channels run, of which at least some are bordered by a wall material made of synthetic quartz glass which has a chlorine concentration of less than 300 ppm by weight, wherein the synthetic quartz glass of the wall material has oxygen deficiency centers at a concentration of at least 2×1015 cm−3.
