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.
Claims20
A method for testing optical receivers, the method comprising:
- placing within a temperature controlled environment:
- a modular testing unit comprising:
- at least one socket configured to support at least one optical receiver;
- and
- one or more optical sources substantially aligned with the at least one socket;
- activating the one or more optical sources to apply an electrical and/or an optical stress to the at least one optical receiver;
- performing one or more testing operations without removal of the modular testing unit from the temperature controlled environment to determine a drift associated with the at least one optical receiver during a time period between a Time=0 and a Time=X as predictive of a reliability failure for the at least one optical receiver.
4 more elements
A scalable system comprising:
- a backplane interface defining a plurality of connection slots;
- at least one modular testing unit received by one of the plurality of connection slots, where the at least one modular testing unit comprises:
- at least one socket configured to support at least one optical receiver;
- and
- one or more optical sources substantially aligned with the at least one socket;
- driving circuitry operably coupled with the backplane interface and configured to drive the one or more optical sources to apply an electrical and/or optical stress to at least one optical receiver;
- and
- a control unit operably coupled with at least the driving circuitry and the backplane interface and configured to determine a drift associated with the at least one optical receiver during a time period between a Time=0 and a Time=X.
