【Abstract】 A new fully automated EDFA test system was implemented. First the hardware part of the system is configured according to the principle of time domain method, the automatic test for EDFA is realized which by using the GPIB interface. The test efficiency is improved, manual operation is no longer needed and the complexity of EDFA test is reduced. The system software was written in LabVIEW. The software was designed with modular pattern, which is of high cohesion and low coupling. The reusability and extensibility of software is good. It is also easy to maintain and modification. This system could be used for other optical amplifier with only small modification to its hardware and software.更多还原
