METHOD OF MAKING SEGMENTED CORE OPTICAL WAVEGUIDE PREFORMS |
摘要 |
A method of making a segmented core optical waveguide preform for making fiber that is resistant to attenuation increases due to hydrogen and heat aging. A first core region comprising a silica glass rod containing at least a first dopant is inserted into a central opening of a second core region comprising silica soot containing a second dopant. The first core region and second core region are consolidated together to form a segmented core region and cladding is deposited on the outer surface of the segmented core region.
