1000Base-SX SFP module is not active (even it is detected) on X440 and x450

We bought a 1000Base-SX SFP module to link a 03 stacked Extreme x440 with x450.
The problem is that the module is detected (Red lazer is ON) when it is plugged on the switch but when i put the optical cable on module, the port is not UP (Green LED is not switched on)
The X450 ExtremeXOS version is12.0.3.16 (BootROM: 1.0.3.5 IMG: 12.0.3.16)
The X440 ExtremeXOS version 15.3.1.4 (BootROM: 2.0.2.1 IMG: 15.3.1.4)

the show port transceiver show that:

Port : 2:48

Media Type : SX
Vendor Name : WTD
Part Number : RTXM191-552

That should be the equivalent of "show port transceiver info {detail}" command.
It requires, of course, the optic to support DDMI.

one great thing you can use is

debug show optic slot 1 port 1 that will give you DDMI information about the port.
