This question was closed as off-topic as "Technical Support." Could someone explain why?
The OP isn't asking for technical support on fixing hardware.
He is looking for hardware to use with a mobile device (smartphone or tablet) that would provide the ability to test network cabling, either copper or fiber but preferably both.
Maybe the question isn't as clear as it could be and I have more background into what is being asked (we were one of the sites that the OP stopped at on the way here and we were the ones to direct him here), but that seems to be exactly the type of question that would fit on this site.
Am I wrong? If so, do please let me know how so I will better understand when to direct people here or not.
