[0002] With the rapid development of information technology, optical fiber communication has become an important part of modern communication networks. As the end-user device for optical fiber access, the stability and reliability of the performance of optical modems directly affect the service quality of the entire network. In the development, production and use of optical modems, it is particularly important to test their signal stability and strength in different environments.

[0003] Traditional optical modem testing methods are often limited to a single environmental condition, such as only testing the performance of the optical modem under standard temperature or standard magnetic field, ignoring the various complex factors that may be encountered in the actual use environment, such as temperature changes, electromagnetic interference, etc. These factors may have an adverse effect on the signal transmission of the optical modem, thereby affecting the user experience.

[0004] In order to more comprehensively simulate and test the performance of optical modems in actual applications, a test device that can simulate multiple environmental factors at the same time is urgently needed. However, most existing test equipment has a single function and cannot simultaneously meet the needs of multi-dimensional testing of optical modems such as magnetic field interference and temperature changes. In addition, the operation is complicated and it is not convenient to quickly adjust the test parameters. Utility Model Content
