Hi to all, I'm concern about designing a proper protection from Surges, applies on ports for indoor signal lines (E1, Ethernet) at telecommunication centers. According to ETSI EN 300 386 a surge of 1.2/50 us, 0.5 kV shell be applied between Tip & Ring. Because of lack in space on the PWB we can't put the overvoltage protector (sidactor, TVS) isolation transformer and ... close to the connector were we applying the surge. My questions are:
1. Can I locate only the Sidactor close as possible to the connector, while the isolation transformer is about 45 cm ahead ? 2. Can the trace width after the sidactor, till the transformer, be thin as 5 mills?
