TIA ANSI/TIA/EIA-455-41A

The intent of this test is to determine the ability of a fiber optic cable to mechanically and optically withstand, or recover from (or both), the effects of a slowly-applied compressive force. The following parameters may be measured or observed:

the number of fibers broken during the compressive loading,

the changes in optical transmittance or attenuation during or after the loading,

any change in the outer covering.
