Methods and structures for testing optical subassemblies at higher and lower temperatures

摘要

An assembly and method for testing an optical subassembly by locally heating or cooling the optical subassembly. Locally heating or cooling the optical subassembly can include using a thermal transfer assembly. The thermal transfer assembly can include a thermoelectric cooler. A clamping assembly is provided to place the optical subassembly in electrical communication with a testing assembly. The thermal transfer assembly can be associated with the clamping assembly. After achieving the desired temperature, a data stream is transmitted through the optical subassembly and evaluated for compliance.
