Chip Ethernet Transformer

The PSE port of the PoE switch is not a simple copy and paste of the network port. This article dismantles the design points of the PSE side from five dimensions: network transformer DC bias, multi-port integrated magnetic RJ45 and discrete network transformers, inter-port crosstalk and Bob Smith termination, three-level surge protection and thermal design, and provides a VOOHU on-rack material number selection table.
