Importance of Network Transformers in Ethernet Connections

Why are network transformers used in Ethernet connections? Why is it so important?

Network transformers provide electrical isolation, impedance matching, common mode rejection, DC isolation, preserve SI, etc. This contributes to the reliable and efficient transmission of data over Ethernet networks.

Spot on. Just to add a bit, the electrical isolation aspect is crucial for preventing ground loops and potential differences. This helps in reducing interference and enhancing signal integrity. The impedance matching ensures optimal power transfer between network components. Also, the common mode rejection plays a vital role in minimizing electromagnetic interference. It’s fascinating how these transformers contribute to the overall robustness of Ethernet connections.

Ah ha, so these will stop a network from failing if there is a loop between two switches!?
