As is well known, with the arrival of 10G Ethernet, 10G network transformers have been widely used. Today, the editor will introduce to you the special requirements for using 10G network transformers on transceivers.

Generally speaking, there are POE requirements for 10G network transformers on transceivers. So, how do we determine if the 10G network transformer has POE function?

The difference between two 10G network transformers of the same circuit and size, one with POE function and the other without POE function, lies in the use of internal materials. The reaction of network transformer drawing parameters is generally indicated in the product header description, and the product itself cannot be observed with the naked eye.

For example:

Pulse Electronics: H7008FNL, 10G, NonPoE

Pulse Electronics: H7028FNL, 10G, PoE

The appearance and dimensions are identical; The internal wiring design is also identical; Apart from the difference in printing, the two cannot be distinguished from each other in terms of appearance; The real difference lies in the material used for magnetic rings and enameled wires.

I would like to remind everyone that when purchasing a network transformer, it is important to be cautious of using non PoE network transformers as PoE network transformers.
