Mechanical strength of silica fiber splices after exposure to extreme temperatures [PDF]

open access: yes, 2012
By using a combination of type-I and regenerated gratings, the mechanical strength of optical fiber splices after exposure to temperatures over 1300 C was characterized. Splice strength was found to decrease with temperature with a secondorder polynomial
