Correlation between size and distribution of pre- and post-proof test level flaw of draw-abraded fiber

摘要

The mechanical reliability of single mode optical fiber is determined by the presence of surface Haws such as particles from the atmosphere during drawing or abrasion damage of the fiber surface by physical contact with any hard surface or drawing equipment and its size distribution, which are produced by normal fiber production methods. Proof testing is a common technique to ensure minimum strength of the fiber and eliminate the flaws whose sizes are dependent on the stress applied during proof testing. This paper describes the relation between the size and distribution of pre-and post-proof test flaws.
