in this one link:

Cat basically just stands for "Category" or basic cable able to carry data
at 10mbps, 5e is the type of cable you also have Cat 3 and there is a Cat 6,
with Cat5e the "e" stands for enhanced, it can carry data up to 100mbps.

| true, but the original poster asked about the difference
between category 5 and 5e
knowing the "e" means enhanced, I think he/she was asking
what that enhancement was.
With the exception of noise suseptibility, I couldn't find any
differences.

| From the notes I took while preparing for the exam, Cat5 is rated 100Mbps
and Cat5e is rated fup to 200Mbps. I have read other places that Cat5e is
rated to 350 Mbps. In terms of why you would use Cat5e overCat5, the reason
I was told was to ensure compatability with future upgrades in network
speeds without having to replace cabling.

Cat5e has replaced Cat5 in the standards; while Cat5 is still widely
deployed it is now obsolete and not generally used in new installations.
The two have the same bandwidth rating, which is 100 MHz (*not* 100
Mbps.) The difference between MHz and Mbps has to do with the different
modulation and encoding technologies that can transfer more than one bit
per transition (cycle, or baud). For example, 1000 Mbps Gigabit Ethernet
actually transmits 4 channels at 250 Mbps, each at about 125 MHz -- 2
bits per cycle.
The differences between Cat5 and Cat5e are in the more detailed
performance specifications such as crosstalk, not raw bandwidth. Cat5e
also must pass more tests to be certified.

| I believe the mail difference is that the physical copper wires inside are a
little bit larger.

| Hi Charles
more twists per foot?
insulated pairs?
