An RJ45 Ethernet cable is a network wire used to link machines with each other or connect them to a wired internet association or LAN (Local Area Network). Its 8-pin connector offers data transfer speeds of up to 1 Gb/s (Gigabit per second) making it one of the most popular standards used when connecting computers, switches, routers and other networking gadgets. These cables can come shielded or unshielded as well as various lengths and categories that accommodate technical networking needs.

Noyafa NF-8601S Overview

The Noyafa NF-8601S TDR Cable Tester is a small, easy to handle device ideal for testing and tracing activities on different Ethernet cables types such as cat5e, cat6, cat6a, cat7, power cable (4+2 LAN cable, 8+2 LAN cable), Tel cable, and Coax cable. It features an LCD with user-friendly interface along with cutting-edge TDR technology as well as various testing features for continuity checks, tracking shorts, length assessment and quality examination.

The Working Principle: The Noyafa NF-8601S takes advantage of the TDR (Time Domain Reflectometry) technology to measure a cables electrical impedance and reflectance. This allows the user to detect faults and determine the exact length of the cabling.

Noyafa's NF-8601S tester measures the time it takes for the signal to travel from one end of the cable to the other. As a result of this measurement, the Noyafa NF-8601S tester can determine the length of the cable and the location of faults.

Tracing RJ45 Ethernet Cables with Noyafa NF-8601S

Tracing Ethernet cables with the Noyafa NF-8601S is a straightforward and efficient process.

Using the Noyafa NF-8601S TDR Cable Tester, you can trace your cables using the following methods.

Method 1: Trace RJ45 Ethernet Cable using Port Flash

The port light on the Switch/Hub can be used to visually trace the live RJ45 Ethernet cable. However, this method only works for good network cables.

1. Insert batteries into the Noyafa NF-8601S cable tester and switch it on.

2. Enter the Main Menu and press the Port Flash icon.

3. You now have a blue screen with a blank red circle.

4. Plug the RJ45 Ethernet cable into the POE/PING port on the main unit.

5. The hollow red circle will start flashing to a solid red circle at a certain frequency.

6. Now look at the switch port where the target cable is connected.

7. The light on the switch port where the other end of the target cable is connected will flash at the same frequency as the red circle on the display, indicating the location of the cable.

Method 2: Use the "scan" function to trace the RJ45 network cable.


This method effectively found and located the targeted RJ45 Ethernet cable among unknown cables.

1. Turn on the NF-8601S scanner (host).

2. Now plug the target Ethernet cable into the "RJ45 Scan" port on the host computer.

3. Select the "Scan" function in the main menu. The main unit defaults to "low frequency" scanning mode. (But you can also switch to PoE switching mode and RF scanning mode according to your working situation.)

4. Now press the "Power" button on the receiver unit to turn it on. (Note the light to confirm that the receiver is powered on.)

5. Press the "SET" key once until the indicator light labeled "SCAN" lights up red.

6. Now bring your receiver to the other side of the target line to scan and track the target line.

2. Plug one end of the target RJ45 cable into the main unit's "RJ45 Main" port

3. Plug the other end of the target cable into the “RJ45” port on the remote sensing unit.

4. In the main menu, select the "Mapping" function and then select the correct cable type (cat5e, cat6, cat6a, cat7) .

5. Once the device is selected, it will run the test automatically and display one of the following results:


A. "Cable open or too short":


The cable is not properly connected to the main unit or the remote unit, or the cable is too short to perform the test.


B. Correct connection


R = remote identifier, M = main tester, G = ground


You see the diagram (same as above) when testing a shielded RJ45 Ethernet cable with a good connection using the remote identifier.


C. Short circuit


In the event of a short circuit, the type of chart shown above will be displayed, showing the PIN, location and distance.

Note: The example diagram above shows the Ethernet cable short at pins 38 and 45 at a distance of 49.3 meters.


D. Open circuit


If there is an open circuit, the type of chart shown above will be displayed, mapping the PIN, location and distance.

Note: The example diagram above shows the Ethernet cable shorted on pins 2 and 5 at a distance of 97.2 meters from the remote unit start end.


E. Across


The diagram above shows the wire being crossed.

Note: The example diagram above shows that pins 2 and 5 of the Ethernet cable are crossed.


F. Open, short, transverse 


Ethernet wires sometimes have opens and shorts, as well as crossed wires. In this case, the above graph appears.

Note: The example diagram above shows Ethernet cable pin 3 and pin 8 shorted, pin 1 open and pin 2 and pin 5 crossed.

Network cable installation is one of the most important parts of a network, but it is often overlooked and undervalued because it is hidden behind the scenes and no one can see it. But the truth is that network cable setup has a huge impact on network performance and the overall technical setup experience. Here are useful ways to install a network cable that you should not ignore.

Cross the cable at a 90 degree angle

Before starting to run cables from our patch panel, one thing must first be done: network cables must be crossed at a 90 degree angle. This is for both power and network purposes, although this is irrelevant for a single UTP cable.

To do this, cut all the network cables at a 90 degree angle, and then connect them to the cross-connect blocks. Once this is done, you can start working on your wiring project without any problems. The 90 degree angle ensures proper airflow around all network cables in the rack or cabinet.


It also prevents network cables from being crossed and ensures proper grounding for safety reasons. If you are going to use fiber optic cables instead of copper cables, make sure they are properly terminated as well. Also, don't forget to test each network cable after installation.


Always test network cables with an OTDR device to make sure they work as expected. This will help you avoid potential problems in the future. And if possible, try testing your network cables when everything else is working so you know exactly what traffic is going through them. Some network devices may not work properly due to bad cable connection or similar.


Lay the cable in a safe place 

When installing network cables, it is important to keep them away from high traffic areas. A good rule of thumb is to place them in places where you are unlikely to accidentally trip over them or walk over them. If they need to be repaired or replaced, it will be easier and safer if they are not hidden under carpets or other furniture.


Also, be careful not to leave exposed power cords near water, heat sources, or windows exposed to direct sunlight; this can damage the cables over time and reduce their life expectancy. In order for the cables to work as long as possible, pay attention to the routine. And if you're having trouble installing cables, contact a trusted professional for a free evaluation.


There could be a problem with the wiring or the equipment, which could cause more serious problems in the future. It's always better to catch things early before they become costly problems.


Do not tie the cables too tightly


When you're running a lot of cables through a small opening, it's tempting to try to fit them as tightly as possible. However, resist the urge. Too much pressure damages and even cuts the cable jacket, which weakens it over time. Be sure to connect the cables in such a way that they can move freely along their entire length without catching or applying excessive pressure in any area.


For larger packages, use grommets and wire ties to keep everything neat and tidy. And if you must use more than one loop per bundle, make sure they are spaced at least two inches apart (this will give you plenty of room for additional wiring). Overvoltage can cause not only physical damage, but also performance problems such as signal loss and reduced speed.


If you're having trouble wrapping your cables neatly (and I mean, they don't want to sit still), consider using duct tape and some paper clips to keep things tidy. You can also take advantage of spring-loaded cable reels and spools to help organize your cables while they await installation.

Do not leave wires exposed at the terminals

Do not leave exposed wires. Make sure all cables are connected and protected from damage. This ensures proper insulation and also extends its life. Don't leave more than 1/2 inch of wire outside the end, as it can fray over time from adjacent wires or rough edges on the wall if there isn't a smooth curve inside the electrical box.


Once the termination is complete, check for stray wires coming out of the crimp connector before wrapping with a piece of electrical tape and tying (this is especially true for IDC connectors). Junction boxes are also used to hide them from damage by physical contact with people or objects passing by them.

In addition, distribution boxes allow multiple cables to be bundled in one place, making them easier to manage. They also provide protection against water damage because they are usually located on walls that are higher than other areas such as floors and ceilings.
