Product details


NF-8601S, upgrated based on NF-8601, provides full cable testing on different category network, coax, or telephone cable. The intelligent wiremap' feature tests for length, shorts, split pairs, or opens and displays with an intuitive graphical interface where a fault is located. (usingTDR techonology: Time Domain Reflectometry). Besides, finding cables easier and tracing with AC fliter, or locating network port using hub blink feature. It can also test the presence of PoE and PING functions. all these make it a must tool for each network technician.


1. Measures cable length and display the distance to fault.

2. PoE Presence: identify which pins are providing power and detect how much voltage.

3. PING function to test network performance, data packet, min & max time.

4. Tone trace cable with complete AC Interference Rejection, much easier than other tracers on markets.

5. Hub blink for locating network port by the flashing port light on a server/switch/hub/router port

6. Core troubleshooting features; length, distance to fault, graphical wire mapping, opens, shorts

7. TF card included to export data or to online updating. (50 sets, txt format).

8. Roughly locate breakage or short position by tone.

9. Voltage detector: included in receiver (90-1000V)


1. Two tone tracing modes: common switch & PoE Switch.

2. Big LCD color screen 320*240 and lighting lamp in darkness.

3. Data can be stored and exported to PC via memory card.

4. Low voltge alarm function and automatic delay power on-off

5. Rechargeable Lithium battery to supply power.

What is the differences among them ?




working theory



cable types

Cat5e, cat6, cat7, telephone cable, coax cable, power cable

Cat5e, cat6, telephone cable, coax cable,

fault distance

1. measure cable breakage & short distance.
2. Breaks or shorts in multi-pins can also be measured accurately

1. measure cable breakage, NOT short distance.
2. breakage distance cannot be measured accurately if broken pins > 2

testing modes

1. measure with main unit locally
2. measure with main & remote unit

1.only measure with main unit locally


Use/unuse button to open or close the calibration data, no need to load the data again.
use: based on new calibrated data
unuse: based on factory clibration data.

9 sets of calibration data can be saved, users need to load the data after calibration


testing modes

1.measure with main & remote unit

1. measure with main unit and remotes 2. measure with main unit locally (RJ45 MAIN + RJ45 SCAN)


Wiremap with faulty pins and distance

Wiremap only with faulty pins, NOT fault distance

Protocol Compatiblity

More compatible with different brands of routers

Not compatible with some brands of routers sometimes

Data save & export

1. Data can be saved into TF card and export to PC.
2. Data can be deleted by function types can be saved into TF card and export to PC.
2.Data cannot be deleted, can only be replaced after 160 sets
