  • How to use a fiber optic pigtail measuring machine

    How to use a fiber optic pigtail measuring machine

    The best method is to use a bare fiber adapter on the power meter to measure the output of the bare fiber, then attach the splice. Alternately, have the splice attached on the pigtail and couple a fiber to the pigtail with the splice and measure the power.
