This product, Optical Component Coherence Reflectometer, measures distribution measurement of optical reflection with TD-OCT（Time Domain Optical Coherence Tomography） based on the principle of Michelson interferometer. Show an image of the principal above. The light output from the low coherent light source is divided by a coupler and lead into DUT (measuring object) and a movable mirror. When the distance between coupler and DUT, and the distance between coupler and the movable mirror matches, each reflected light come back to the coupler, and interference occurs. The intensity of interference light is proportional to the optical return loss of DUT, so it is possible to know the optical return loss of DUT at that time. Moreover, it is also possible to find out the position of the optical reflection accurately by the position of the movable mirror. By measuring the interference light constantly using the movable mirror, measures distribution of the optical return loss of DUT.
OCCR Apex system measurement distance is 1.2m，the range of optical Return Loss is -10 to -100dB.
