TIA_EIA-455-69A-1991 FOTP-69 Test Procedure for Evaluating the Effect of Minimum and Maximum Exposure Temperatures on the Optical Performance of Optical Fibers
This test is intended to determine the ability of an optical
fiber to maintain optical performance (attenuation and
temperature dependence of attenuation) over an extended period of
time after having been exposed to a specified range of high and
low temperatures.
