Hi everyone:

I was recently told to purchase an ethernet cable for our 10/100/1000
switched LAN, and was specifically asked to get a CAT5E (capital e),
and not a CAT5e (lower case e). An A/V engineer who I generally respect
is the one who suggested this, but I'd always thought they were about
the same.

Can anyone say for sure whether or not there's a difference between
lower and upercase e?

Not that I know of there are diferent cable types for plenum/nonplenum/
fire retardent use and your local building regs may require a
particular type depending on where you are based.

Absolutely positively the same cable. He probably wanted to emphasize the
fact that he wanted a decent CAT5E cable, not the
"everything-one-dollar-store" variety. Just my wild guess.

Hi John,

both relate to exactly the same specification EIA/TIA-568B. It makes no
difference at all whether you write it in lower case or in a capital letter.
In other words, I have never seen a different specification for these
