Optical Module Test

OCI1500 is based on OFDR technology and is suitable in short distance, high resolution and high precision measurement areas. When analysis of internal structure of an optical module, OCI1500 can accurately identify the return loss value of all points at the spatial resolution of 10μm, which provides an effective means for the analysis of the optical module.

The isolation level of an optical module is identified according to the measured return loss value: when the return loss is greater than or equal to 20dB, It means there is a double isolation in the optical module. When the return loss value is less than 20dB, that means single isolation existing in the optical module.
