Bob smith termination
Web• On the input connector, use a Bob-Smith Termination Network to properly terminate the Ethernet connection. • Use input common-mode chokes. • Use a shielded RJ-45 connector. It is possible to use an integrated connector, which can include common-mode chokes, the Ethernet transformer and the Bob-Smith network. WebPassive PoE pretty much just applies 24V across two of the pairs of the ethernet cable (as far as I know - someone correct me if I'm wrong). If the modem ethernet transformer circuit uses standard Bob Smith Termination you're essentially applying 24V over a 150 ohm resistance, which is going to cause those resistors to get uncomfortably hot and probably …
