How do you maintain creepage distance between diff pairs and the LED terminals on an Ethernet connector?
My understanding is that based on EN60950, for 250V IT equipment, the air clearance is 2mm and the creepage distance is 2.5mm. Yet, the placement of LED pins on PCB mount Ethernet connectors almost force you to violate this clearance rule.
Should I be driving my LED’s through a 2kV optical isolator?
Should I be moving my diff pairs to an internal layer? I’ve done this for the unused PoE pairs, but I don’t really want to do this for the active signal pairs because the via’s will act like stubs and introduce an impedance change.
The application notes I’ve found for Ethernet layout seem to only focus on the EMI side of things, and don’t even mention creepage/clearance distances.
Am I trying to solve a problem that doesn’t actually exist? Am I miss-understanding the standard?
Below is a picture of my existing layout.
