Why each option
Crimpers (crimping tool) are the specialized hand tool used to mechanically secure an RJ-45 connector onto the end of a twisted-pair cable, completing an Ethernet patch cable.
A loopback plug is used to test NIC or port functionality and is not a cable-fabrication tool.
A punch-down tool seats individual wire conductors into 110-type or Krone-type IDC blocks on patch panels and keystone jacks, not RJ-45 connector ends.
A crimping tool uses a ratcheted mechanism to simultaneously push the RJ-45 connector's gold contacts down through the cable jacket into the individual wire conductors and compress the strain-relief tab, creating a solid electrical and mechanical connection. Without crimpers, it is not possible to properly terminate an RJ-45 connector on a cable.
A cable tester verifies that a completed cable is correctly wired but cannot be used to attach connectors to cables.
