["Jan Vercammen" <jan.vercammen.jv1@xxxxxxxxxxxxxxxx>]

Hello SI-list,

I have a question concerning the  (electric)  isolation properties of RJ-45
connectors used for 10/100Mbit twisted pair ethernet.

We use an AMP connector (the receptor) and its data sheets states: "the
jack
cavity meets FCC part 68 subpart F".

I have a copy of part 68 code and paragraph 68.304 is about leackage
current
and isolation voltages (between telephone signals and other connections).

I am interested in the electrical isolation. What does this mean in
practice? As
far as I understand it there is a 1000Vrms isolation between the connector
pin(s) and the housing. Or should this be 1500Vrms??

Can anyone provide any details on this??



Kind regards,
