Shenzhen Noyafa Technology Company Limited: The Leading Cable Tester Supplier

In today’s world, technology has become an integral part of our lives. We rely on technology for communication, work, entertainment, and almost every aspect of our daily lives. With this increased reliance on technology comes the need for reliable and efficient tools to ensure that our devices and equipment function properly. One such tool is the cable tester. A cable tester is an essential tool for testing and verifying the integrity and connectivity of various cables and wires. Shenzhen Noyafa Technology Company Limited is a leading cable tester suppliers and related products. In this article, we will take a closer look at the company, its products, and why it is considered a top supplier of cable testers.

Cable Tester

A cable tester is an electronic instrument that measures the electrical connections in a signal cable or other wired assembly. These devices are used to certify cabling installations for compliance with standards developed by organizations such as the Telecommunications Industry Association (TIA), the International Electro technical Commission (IEC), and the International Organization for Standardization (ISO).

A basic cable tester has a source of electric current and one or more voltage indicators. A more sophisticated product may also have a microcontroller and a display to verify test results automatically.

A network cable tester is an essential tool for technicians. These devices consist of a primary and remote tester connected to a computer or router.

Wire Tracker

SHENZHEN NOYAFA TECHNOLOGY Company LIMITED offers a wide range of cable tester products. They also offer a wire tracker that works excellent for locating cables buried behind drywall.

The NF-816 can find wires and cables up to 3 feet deep and 1000 feet away. This makes it an excellent tool for contractors, electricians, and anyone who needs to track down wires.

This wireless wire tracer works with all types of wires, including Cat5, CAT6, coax, speaker, and phone. It also has an auto-shutoff after 45 minutes of operation.

This tracing device sends a signal to the line, and the receiver then detects it with a tone and LED. It can be set to an analogue, digital, or NCV mode. The NCV mode can detect AC voltage presence.

Cable Length Tester

SHENZHEN NOYAFA TECHNOLOGY Company LIMITED offers a cable length tester that is an excellent tool for measuring the length of network cables. It uses Time Domain Reflectometry (TDR) to determine the length of wires in cabling.

TDR is an accurate and precise measurement technology that relies on the time a signal travels through the cabling to estimate the length of the cable. However, the accuracy of TDR measurements can be affected by other factors, such as the Velocity of the Propagation value of a cable and how the test is performed.

The NF-8209 is a multifunctional TDR cable length tester that can test different kinds of network cabling. It can detect network cable faults such as open, short, cross, reverse connection, and broken wire positioning.

Optical Power Meter

Optical power meters measure average optical power in fibre optic systems using photodiode sensors, usually based on silicon (Si) or near-infrared, and also on germanium (Ge). They are generally less sensitive than thermal power meters and perform well in the microwatt range.

Typically, they display time-averaged power levels and may be capable of measuring pulses at low pulse repetition rates. Nevertheless, this requires the input signal duty cycle to be known and pulse peak power levels to be well below the maximum meter reading, or the detector will saturate and result in wrong average readings.

Optical power meters are used during network commissioning to verify that the transmission equipment meets design specifications for both loss and output power. Test results are then stored as part of the network commissioning test data set.

Engineering Treasures

SHENZHEN NOYAFA TECHNOLOGY Company LIMITED is one of the best cable tester suppliers, offering a wide range of products. These include LCD cable testers, CCTV monitor testers, underground wire locators, laser range finders, optical power meters and engineering treasures.

NOYAFA NF-8209 Network Cable Tester is a great product that measures continuity and checks for connection errors in UTP or STP twisted pairs. It also tests the physical status of the LAN cables and can detect AC voltage presence (50V-1000V). The tester also offers Ethernet link testing and LED flashing to help you locate the port on the Hub or Switch. NF-8209 can also be used for PoE testing, identifying which pins provide power, detecting how much voltage, and identifying the type of PSE (at/af standard). It has a long list of features, making it an excellent choice for any organization that needs to test its cabling.


Shenzhen Noyafa Technology Company Limited is committed to producing high-quality testing equipment. The company uses only the best materials and components in their products, and each product undergoes rigorous testing to ensure that it meets the highest standards of quality and reliability.
