Ethernet and Others

GAO Tek offers a selection of affordable and high-quality Ethernet Testers and other cable solutions such as time analyzers, and PTN/IP RAN testers. Products under this category are designed for telecommunication testing and have protocols that measure accuracy up to nanosecond. Furthermore, they are designed to analyze, and evaluate the synchronization deviation on a variety of time and frequency interfaces. Our products are built to improve both work efficiency and quality at the same time.

Functions of Ethernet and Others

Ethernet Testers are handheld devices that integrate functions such as network test and monitoring, data packet sniffing, traffic generator, cable test and BER test into one single unit. It is widely used in testing BER of layer1, layer2, layer3, and full-featured RFC-2544. It can also analyze the network quality and locate the fault rapidly.

Time and frequency analyzers evaluate time and frequency synchronization and perform high-precision measurements based on the IEEE 1588v2 time and clock synchronous system. It also performs statistics and analysis on time signal with random deviation and makes the creative asymmetric compensation measurement.


GAO Tek’s Ethernet Testers and other cable products are affordable, ergonomic, and portable products. Our products have several special features designed to enhance performance, which include LCD color touch screens with smart menu-driven operations, and auto power save functions. Other features for these products are large storage capability, display of results graphically or numerically, and RFC2544 automated test, capable of fast network testing and locating the fault. Additionally, some of the products have real-time capture and display TOD messages, store test results of TOD seconds deviation and real-time display of PTP protocol synchronization process, and show the grand clock information.

Applications and Industries

GAO Tek’s Ethernet Testers and other cable solutions have a variety of applications. Some of them include helping technicians to confirm that the traffic they are transmitting is getting properly received, and determine if the link has errors or is operating nominally. The products are used to evaluate the performance of various devices, services, and network systems with an Ethernet interface. They can efficiently and accurately verify whether network systems and services meet the specified quality and functionality. Other applications include terminal mode test, traffic performance test, data loopback, G.703 E1 PING test, and V interface PING test within others.
