Fibre Connection Shows Signal but no Link

Hi,

I'm really sure I made a configuration error but I just can't find it. I hope you can help.

One Side is a HP FlexFabric with a compatible 10Gb LR LC SFP+ and the other Side is a Aruba 2930F with the same SFP+. Inbetween is a Third-Party Fibre.

I finally have a Connection:

 Transceiver in 27 Interface Index : 27 Type : SFP+LR Model : J9151E Connector Type : LC Wavelength : 1310nm Transfer Distance : 10.0km (9um), Diagnostic Support : DOM Serial Number : CN93KBW1PF Status Temperature : 41.875C Voltage : 3.2966V Tx Bias : 36.008mA Tx Power : 0.6243mW, -2.046dBm Rx Power : 0.3038mW, -5.174dBm 

Bit I have no Link on the Port. Here is the Config on the HPE Side:

 interface Ten-GigabitEthernet1/2/11 port link-mode bridge description Link port link-type trunk port trunk permit vlan all port trunk pvid vlan 21 

and here is the Aruba-Side:

hostname module 1 type jl255a snmp-server community unrestricted snmp-server contact location " vlan 1 name "DEFAULT_VLAN" no untagged 4,24,27-28 untagged 1-3,5-23,25-26 no ip address ip igmp ipv6 enable ipv6 address dhcp full exit vlan 21 name untagged 24,28 tagged 27 ip address 192.168.21.20 255.255.255.0 exit vlan 81 name untagged 4 tagged 27-28 no ip address exit vlan 91 name " tagged 27-28 no ip address exit vlan 101 name tagged 27-28 no ip address exit vlan 111 name tagged 27-28 no ip address exit vlan 121 name tagged 27-28 no ip address exit vlan 131 name tagged 27-28 no ip address exit vlan 144 name tagged 27-28 no ip address exit vlan 171 name tagged 27-28 no ip address exit spanning-tree allow-unsupported-transceiver 

I have no idea why I don't have a link... any Tips?
