Abstract :
We have clarified the strength and estimated lifetime of fluoride fibers for optical amplifier use. We fabricated a UV-curable epoxy-acrylate coated fluoride fiber with a strength of 542 MPa. We estimated the lifetime of the fluoride fiber to be longer than 25 years at 80/spl deg/C and 50% RH.
