Abstract
The present invention relates to an apparatus and to a method of measurement of optical loss of a DUT having a first end and a second end, comprising the steps of: coupling an optical signal into the first end of the DUT, measuring the optical power of the optical signal by a first detector, reflecting the optical signal at the second end of the DUT to send back a reflected optical signal into the DUT, measuring a reflected optical power of the reflected optical signal by a second detector, evaluating a two-way optical loss on the basis of measurements of the first and the second detectors.
