Abstract Based on the research of more than 20 international standards related to shielding
effectiveness test method for communication cables, connectors and their assemblies, five
test methods for shielding effectiveness which are commonly used are summarized. The
theory, applicable product scope, frequency range, dynamic range, advantages and
disadvantages are analyzed for each method. And the matters needed to pay attention to
while using each test method to test, are also mentioned.
Keywords shielding effectiveness; communication cable; connector; assembly; test method
