Abstract
There is provided an optical loss testing system for multi-fiber array cables an optical loss test method and a reference method therefor which overcomes at least part of the multi-powermeter uncertainty. A prior calibration step serves to characterize the relative difference in optical power response of the multiple power meters. This relative difference can then be used to correct the optical loss measurement so as to eliminate its effect.
