Q51:What are the Validating Test and the Authentication Test of the cables?

A:A51: The validating test is used to test whether the lengths of the cables and the connection of the twisted pairs are correct, but it could not be used to test the electric index of the cables. The Authentication Test is used to test the performance of the cables according to some international standard. It includes all the contents of the Validating Test and the indexes of the standard testing cables, such as attenuation and impedance, etc. The Validating Test could not ensure whether the cables can pass through the high-speed data signal of the network, such as 10M or 10MHz. Only the cables fixed achieve the corresponding index so that they can support the signal of 10M or 100M.
