Test and Research of Ethernet Physical Layer Chip Photoelectric Characteristics
At present,Ethernet physical layer chip is indispensable in the field of many applications,and the functional performance requirements of Ethernet physical layer chip is getting higher and higher.Therefore,how to verify the photoelectric characteristics of chip functional performance is an urgent problem to be solved.The technical status of verification of Ethernet physical layer chip is mainly introduced,and a photoelectric charac-teristic test method that meets the functional performance application requirements of Ethernet physical layer chip is put forward.Test instruments(such as oscilloscope,logic analyzer,network vector analyzer,etc.)and verification board are used to test the electrical and optical characteristics of data transmission of physical inter-faces in the network.The test results show that the proposed test method meets the test requirements,meets the application requirements of functional performance,and then improves the technical means of domestic high re-liability Ethernet physical layer chip verification.
