The DEC 3852 has 2 SFP+ Ports an we tried following SFP+ Modules:
- Unifi Direct Attach Cable:

you see we always get: mod_absent but the Direct Atach and the 10G Module is on your compatibility list
we tried the modules and cable in switches, they are working perfect
problem: the ports not going up (no link etc)
with fabric new opnsense DEC3852 with default configuration
Software version used and hardware type if relevant, e.g.:
OPNsense 24.10_7-amd64
DEC3852
Not sure of the chronological order of the dmesg output, but any empty port starts with the mod absent state, and as soon as something is plugged in the module information is printed, as is the case with all of your modules.
The port_sfp_inputs 0x2 value indicates the module is not linking with the other end, the module is still negotiating, or the other end is not plugged in at all. DACs always show 0x0 there.
You can try to kickstart it by assigning an IP address on the port, but I have no context of your environment nor the steps you took to reproduce it, there is also no confirmation that there is no link (ifconfig output or dmesg | grep Link).
