Buying Guide

Match tester to cable type

Choose a tool that supports the connectors and media you use most often (RJ11/RJ45 for copper, 2.5mm/FC/LC for fiber)

Prioritize diagnostic functions

Look for features you need day-to-day such as continuity mapping, tone generation, PoE detection, or visual fault locating

Check range and sensitivity

For fiber VFLs and optical meters, confirm reach (km) and power range to suit short patch cords or longer drops

Consider build and ergonomics

Durable construction, clear displays, and easy-to-use probes make handheld testers faster and safer to use on job sites

Compatibility and adapters

Ensure the tester includes or supports adapters you need (FC/LC/ST, RJ11/RJ12/RJ45) to avoid extra purchases
