ATEM Talckback Converter 4K and BM Studio Fiber converter

Is it possible to connect BM Studio Fiber converter to ATEM Talkback converter 4K using OPTICAL I/O connectors? I have 2 ATEM Talkback converter 4K and 10 BM Studio Fiber converter. I have tested many options but it never worked. Maybe I'm wrong and the Optical I/O connector on the BM Studio Fiber converter only works with the Mini Converter Optical Fiber 12G?
