Qualification Information
Photodetector module has passed reliability assurance requirements as specified by GJB 8120-2013.
Precautions
— The fiber bending radius no less than 20mm for avoiding fiber damaged.
— Be sure the fiber coupling facet is clean before connecting it to opto-circuit.
— The suitable ESD protection is required in storage, transportation and using.
