Using a Circulator to Make Insertion Loss Measurements in Transmission with the Optical Backscatter Reflectometer (OBR)
LUNA’s Optical Backscatter Reflectometer (OBR) is well suited for making localised Insertion Loss (IL) measurements in reflection using the differences in fibre Rayleigh scatter amplitude on either side of a loss event. This engineering note details how the use of a circulator can allow the user to measure the total IL of their Device Under Test (DUT) in transmission.
