it's a pigtail between two modules inside of the counter. I've fixed it already, took it apart, to pun intended, soldered it back together and it works... not sure about the performance because I can't really verify it. I want to get replacement anyway just to ensure the quality of the signal.
I couldn't crimp the connector correctly... but I guess I've done my best.
And yes, it is SMB, I've found replacement already, $3.44.
