德国EMCTOOLS的用于总线信号转换的光电模块（FO），包括两个模块，分别安置于EMC实验室（电波暗室及屏蔽室）内部和外部。用于传输待测物（DUT）和辅助设备之间的总线信号。这种FO把总线电信号转换后，以光信号的形式，穿过EMC实验室。如果使用电缆在实验室内外传输总线信号，电缆穿过EMC实验室的屏蔽钢板时，会导致的屏蔽效被破坏。而这种光信号的传输方式避免了屏蔽效能被破坏，这样的EMC实验室在EMC测试过程中，能在EMC实验室内外正常的传输总线信号。此类FO在使用过程中，可以满足汽车EMC测试标准对于DUT的要求。并以其的EMC性能和的通信成功性能，大大节省了用户调试过程的时间。这使EMC测试得以进行。因为这种FO主要应用于汽车EMC领域，需要其具备如下性能：EMI性能——满足CISPR12 / CISPR25的测试性能要求EMS性能——满足ISO11451 / ISO11452的测试性能要求ESD性能——部分型号配合ESD保护器，可满足ISO10605的测试性能要求各大主机厂车辆EMC测试标准（引用以上标准）。
