Abstract: Disclosed are a testing unit, system, and method for testing and predicting failure of optical receivers. The testing unit and system are configured to apply different values of current, voltage, heat stress, and illumination load on the optical receivers during testing. The test methods are designed to check dark current, photo current, forward voltage, and drift over time of these parameters.
