Testers and certifiers to check your cabling works.

A network tester checks that each cable is wired correctly end to end. A certifier goes further and proves the link meets its rated grade, such as Cat6, which some projects require.

Tester or certifier?

Tester: confirms wiring and finds faults like a crossed or broken pair. Fine for most day-to-day jobs.
Certifier: measures performance against the cable standard. Use it when a client or warranty needs proof.
Cable and parts: see bulk network cable.
