When you need to sort out a broken network connection, the real fork in the road is between a straightforward cable tester and an advanced locator with a screen. For rf network cable telecom test work, the NF-802MG and the FNIRSI LPM-10A represent that split. They also sit at different price points, so the right choice depends on how much diagnostic depth you need.
Quick verdict
Pick the NF-802MG if a lower listed price and a straightforward tester fit your workflow. Pick the FNIRSI LPM-10A if you want more diagnostic depth in a single tool.
Where each product wins
- The NF-802MG wins on the price side and keeps the essentials together: PoE/Cat cable checking, RJ45/RJ11 compatibility, NCV, and SCAN.
- The FNIRSI LPM-10A wins on feature depth: locating, display, length, and diagnostic modes bundled into one tool.

Product notes
NF-802MG Network Cable Tester Ethernet Cable Tester with NCV and SCAN for PoE/Ca
The NF-802MG is built around cable diagnostics and tracing. It supports PoE, Cat5, Cat5e, Cat6, Cat6a, CAT3, LAN, and Ethernet cables with RJ45 and RJ11 compatibility, and it covers opens, shorts, crossed pairs, and wiring faults. Non-contact voltage detection and SCAN make it useful for quick checks near powered equipment. The listed dimensions are 5.5 x 2.5 x 1.2 inches and the weight is 3.2 ounces, so it is easy to carry between patch panels. The main limitation is scope: its feature set is centered on testing and tracing, so if your task starts with locating one unlabeled wire in a bundle, the FNIRSI LPM-10A is the one with anti-interference locating in its description.
FNIRSI LPM-10A Network RJ45/RJ11 Cable Tester Anti-Interference Line Finder US
The FNIRSI LPM-10A is the more feature-dense option. Its anti-interference locating is designed to identify the right cable in complex environments, and the 2.4-inch HD TFT color screen gives you a clear readout. The listed modes include full-range cable testing, PoE mode identification, error checking, duplex mode detection, length measurement, port flashing, crimp testing, and faulty line detection. Power comes through a TYPE-C 5V/1A connection, so plan for that power source. This package makes sense when you need measuring and locating as well as continuity checks. If your work is limited to quick continuity checks, this model carries more functions on board than that simpler workflow would ask for.
Final choice by use case
- For a lower listed price and a portable tester focused on core cable checks: NF-802MG Network Cable Tester at USD 39.99.
- For a more feature-dense line finder: FNIRSI LPM-10A Network RJ45/RJ11 Cable Tester at USD 68.99.
