Aiming at effect of ohmic heating cycle times on durability of optical fiber

select optical fiber imported from Britain

laboratory test by circulated ohmic heating metal-clad optical fiber

obtain pull-displacement curve of optical fiber under different ohmic heating cycle times

the maximum tensile resistance of metal-clad optical fiber under different ohmic heating cycle times is obtained. Relationship between ultimate tensile resistance of optical fiber and ohmic heating cycle times is analyzed

durability of optical fiber prediction equation is obtained. Research result indicates that with the increase of ohmic heating cycle times

metal-clad optical fiber maximum tensile resistance continues to decline at an increasingly rapid pace. The results has an important guiding significance to the corresponding project make a reasonable choice to detect sensing optical fiber with same durability.
