First, according to the medium transmitted by the Ethernet Signal Tester, it can be divided into two types: a wireless network tester and a limited network tester. The wireless network tester diagnoses the wireless router and the AP, and can view the connection terminal and signal strength of the wireless network, thereby managing accordingly and enhancing a security of the network. The wired network mainly performs network debugging by using twisted pair, optical fiber and coaxial cable as the transmission medium, thereby performing network debugging.
Secondly, according to the function, it can be divided into cable detector, multi-function Network Emulation Tester and network performance tester. The cable tester mainly performs a test on its medium, including some cable specifications, lengths and circuit diagrams. The multi-function network tester is a test device that integrates various test functions such as cable diagnosis, POE detection and topology detection. The network performance tester has a high-end device for network traffic testing, data interception, and IP query.
Finally, it is divided into network construction equipment and network maintenance equipment according to the purpose of the network tester. The network construction equipment is more suitable for accurate measurement of some data in the network construction; and the network maintenance equipment is not obviously distinguished from the network construction equipment, and has multi-functional and multi-purpose.
