Fluke Networks TS-100 TDR Tester and Toner: Is This $175 Cable Fault Finder Worth It?

The Fluke Networks TS-100 Cable Fault Finder combines TDR and toner functions in a portable package. With leads and case included, this lightly used tester offers a practical option for network and telecom cable troubleshooting.

Last updated Aug 15, 2026

Fault hunting on network and telecom cable runs can turn a quick fix into a slow crawl when you don't know whether the problem is a break, a short, or a bad termination. A TDR sends a pulse down a line and measures the reflection to locate the fault, while a toner lets you trace wires at a patch panel or jack. The Fluke Networks TS-100 Cable Fault Finder packs both functions into one handheld tool, and with a $175 price tag that includes leads and a case, it's worth a close look.

Quick verdict

The Fluke Networks TS-100 is a practical two-in-one tool for anyone who works with network or telecom cable. It combines time-domain reflectometry with toner capability, so you can find a break or short and also identify which wire is which. The included leads and case mean the kit arrives ready for the field. The trade-off is that this is a used unit, so its long-term performance depends on the condition of the electronics and the leads.

Who it suits

This tester fits technicians who need a portable, grab-and-go fault locator for everyday cable work. If you're maintaining office network wiring or telecom circuits, the TS-100's dual TDR and toner functions cover the two most common cable tasks. It also works well as a backup tool to keep in a van or tool bag when you don't want to drag out a larger certifier.

What stands out

The TS-100 puts a TDR and a toner in the same casing, so you can switch between locating a fault and tracing a wire without grabbing a second tool. The bundle comes with test leads and a carrying case, meaning it's ready to travel. It's a lightly used unit, and it was made in the United States. At $175, you're paying for a two-in-one test device rather than a bare cable tester.

Meaningful trade-offs

The biggest unknown is the used condition. Even though it works like new, you're buying a tool with an unknown history, so the accuracy of the TDR readings and the integrity of the leads are worth confirming before you rely on it in the field. The price of $175 is a real commitment for a single-purpose tester, and if your work only needs a simple toner, this two-in-one might be more than you require. On the other hand, if you regularly chase cable faults, the combined TDR and toner function can save you time.

Bottom line

If you need a dedicated network cable tester that can both find faults and tone wires, the Fluke Networks TS-100 is a competent choice at $175. The included leads and case add convenience, and the two-in-one design keeps your tool bag light. Just verify the unit's condition when it arrives, and you'll have a practical tool for cable troubleshooting.
