For option C, I vaguely recall something about the DFIU boards needing specific wavelengths, but I can't remember if it was 1511 nm or something else.

I remember practicing a question about IEEE 1588v2, so I feel like option B could be true, but I need to double-check the OTDR functions.

I think option A sounds familiar, but I’m not entirely sure if the TM1 and TMI1 ports have to be directly connected.
