FIELD: testing of optical apparatus.
SUBSTANCE: method comprises feeding the standard optical signal to the light guide to be tested and measuring reflected signal. The oscillation of the signal power with the amplitude exceeding that of the initial level indicates the presence of a defect.
EFFECT: enhanced reliability of testing.
