Incorrect.

RJ-45 is for a dedicated single pair data circuit, and has nothing to do
with ethernet.

The connectors themselves do not have any RJ designations until they are
wired for a specific telephone application, as originally defined in
47 CFR 68.502.

The only exceptions might be jacks for alarm applications complying with
RJ-31X or RJ-38X, which have shorting bars, making them difficult to use
for other applications.

Ethernet and Token Ring do not have any RJ designation.

, in the day to day
residential world this is the way its done RJ-11 for telephone and RJ-45
for ethernet.

I remember someone saying they ought to be called 6P4C and 8P8C (and
RJ12 is 6P6C, what is 4P4C or 10P10C?). That describes the specific
connectors, but sounds awkward.
