Thanks Rob


That’s a match.  It’s an OSP – spec to 22 GHz.

Looks like a push fit connector for modular system, like OSP...

Thanks for all the comments so far.


It’s definitely not SMB, SMC or RP-SMA.  It could be a variant of QMA, but it has a male centre pin, the insulation is too well recessed and the external ridges are outside the formal spec.


It could have been used as a test point on a piece of equipment, so may not even be a standardised connector at all.  Anyway, the leads are useful as they have SMBs at the other end....
