Technical Optoelectronics Test Information Active optoelectronic device a very small, precise reverse current (10nA) characterization requires more while measuring the voltage. The limited cur- Imeter/Compliance Local IN/OUT HI than a current source rent prevents permanent damage to the device, Remote SENSE HI while allowing a precise breakdown voltage to Vsource Vmeter Forward L be measured. Given the breakdown voltage, it's DUT Voltage (VF) V now possible to force a reverse bias that won't Feedback to Adjust Vsource Back Facet IBD harm the device while leakage is measured. This Remote SENSE LO Detector Current dL/dIF leakage current value is often used to qualify the Local IN/OUT LO device for further testing.
