Abstract

The long-term mechanical reliability of polarization-maintaining and single-polarization single mode optical fibers drawn from ground preforms is of growing interest. This paper will report the results of the static fatigue tensile strength behavior under axial load at ambient conditions for PM and PZ types of single mode fiber produced from five ground preforms. The measured values of the fatigue resistance parameters N (22.6 +/- 1.3 to 27.9 +/- 1.5) are consistently higher than the N-parameter of 19.7 +/- 0.5 measured under identical conditions for standard commercially available single-mode fiber drawn from non-ground preforms. Large Weibull moduli of fiber from ground preforms suggest fiber of uniform strength distribution. Although fractographic analyses of failed fiber end faces do show extrinsic failure modes due to micro-cracks and zirconia particulates and intrinsic failures due to molybdenum inclusions, the analyses do not reveal failure modes peculiar to diamond grinding or high internal stresses.
