Trying to connect a FritzBox 5530 to a Nexus 3064-X

Hi, 

I am trying to connect a FritzBox 5530 AON to a Nexus 3064-X, however the port doesn't come UP. I already tried this setup with different switches (Nexus 3172PQ-XL and Nexus N9K-C92160YC-X) and in those cases the link is established. Also tried to connect the Nexus 3064-X to a measuring device (EXFO EX1) and even there, the link is established. The Nexus 3064-X was also connected to another Nexus 3064-X and this also works with the SFPs I used.

Is there something that I am missing on why the FritzBox won't connect with the Nexus 3064-X ?

Versions: 

Nexus --> NXOS 7.0(3)I7(9)

FritzBox 5530 --> 7.50

Used SFPs: 

Nexus :

a7c3d693-86ec-4761-ae18-595de1cff61d.png

FritzBox --> 1G SFP 1310/1550 10km (SFP-GE-BX) from FiberStore

Config of the port in which the FritzBox is connected to:

   - At the nexus side ,  verify if  the used SFP model is supported for this Nexus 3064-X , according to https://tmgmatrix.cisco.com/
     Also try toggling speed auto/fixed at both ends to see if that can help.
     Try flipping fiber pair on  patch cord (connection)
     Check the logs on both devices  when the connection is attempted to see if there are any error messages that can provide clues on what could be causing the issue.
