VDSL-SFP RB3011UiAS-RB

Yesterday I tried to use a ALLNET ALL4781-VDSL2-SFP with a RB3011UiAS-RB, but it doesn´t work.
I allready installed the latest firmware.
The SFP successfully synced to the DSLAM, but the link is still down.
I also tried to disable auto-negotiation.
The same configuration worked with the RB2011UiAS-IN (latest firmware) with the same SFP and the same DSLAM.
The only difference I recognized was “Rx Lose” on the 3011.
There are similar cases in the mikrotik forum with other SFPs and the RB3011UiAS-RB.
Is there a way to get this thing working?
Do you have experiences with other VDSL-SFPs on MikroTik RouterBoards (3011)?
Looking forward to hearing from you.

I have the same problem with the RB3011. The same module works in a RB962Ui. Is there a solution to the problem in sight ?
