from what i understand since they are SMPTE compliant devices any device which can rx/tx on the same wavelength should work just fine. I would imagine they would be the same as the OpenGear cards/MiniConverters/Camera Converters ...
As for single mode/multi mode ... its been pretty well documented on the forum that the other devices are single mode ... but multi mode fiber will pass signal ... just not very far at all.
see below just found the thread:

Although someone from BMD would need to confirm.
