Which tool is used to verify copper cable continuity and correct pinout before installation?

• A. nmap
• B. Cable Tester
• C. Light Meter
• D. OTDR

Answer: (B)

Testing copper cable continuity and pinout is about confirming that every conductor in the cable is connected end-to-end and that the wiring order matches the expected standard. A Cable Tester applies signals through the wires and checks each path, so you can see if there are opens, shorts, or miswired/pinout errors. This ensures that when you install the cable, the network will function correctly and you won’t run into connectivity issues caused by a bad or miswired termination. Other tools don’t fit this job. A network scanner like nmap is used after wiring to discover devices and services on a live network, not to verify the physical cable. A Light Meter measures light levels for fiber optic applications, not copper cables. An OTDR is designed to analyze fibers by sending pulses and detecting reflections to locate faults along a fiber, which again is not for copper cabling. So, the tool best suited for verifying copper cable continuity and correct pinout before installation is a Cable Tester.
