I'm rejiggering my test setup to use FC/APC connectors, and I notice in the OFR catalogue that their barrel connectors come in two flavours, narrow-slot (2.0 mm) and wide-slot(2.14 mm). I gather that the narrower ones are good for APC because they reduce fretting and so on, but I don't know whether these barrels play well with other types (say normal FC or FC/PC).
Are normal FC barrel connectors suitable for APC, or should I replace the ones I have? And if so, should I get narrow or wide types?
Thanks,
Phil Hobbs
