The difference between 100M and gigabit network transformers

To sum up, the biggest difference between 100 mbit/s network transformers and gigabit network transformers is that 100 mbit/s network transformers have only two groups of lines, while gigabit network transformers have four groups of lines.

The two windings of the 100 mbit/s transformer are connected to the network port with 1/2 and 3/6 pins. A pair of windings are used for sending and receiving signals. The transmission rate of each group is 100M.

Gigabit network has four transformer, i.e., with four lines, corresponding to the front-end ports were 1/2, 3/6, 4/5, 7/8, four windings should be used when the transmission signal, each pair of windings network signal transmission can send and receive at the same time, when the transmission rate is 250 m, 4 of winding is 1000 m, it is worth noting that it to send and receive two direction of carrier frequency is not the same.

Generally speaking, the network transformer 16PIN and the following products for 100m products, and 18PIN 24PIN and above PIN PIN products for gigabit products.

Generally speaking, the gigabit transformer has four groups of lines, and it can be replaced by two two groups of gigabit transformers to use,and the 100 m transformer only two sets of lines can not be replaced by the 1000 M transformer to use.

This is the difference between a gigabit and a gigabit network transformer in a popular sense.
