Cat5e

Hi could someone please tell me if Cat5e is crossover cable?

TIA

There's no way you could tell just given that.

Cat 5e is a standard that refers to the electrical properties of the
physical wiring and insulation.
It has nothing to do with the way that its made into patch leads.
The actuall copper wires inside the cable can be connected to RJ-45 plugs to
make either straight through or crossover cables.

It's cable.... it has 4 x twisted pairs.

How you wire it makes it straight through or crossover.....

Although it's quite possible to make a crossover out of CAT5E it's
unlikely you'll ever see one. CAT5E is the standard required for gigabit,
and gigabit does not require a crossover to connect two NICs. You use a
crossover to connect two 10/100 NICs and CAT5 is good enough for that, and
cheaper. So a crossover will normally be made from CAT5.

Except plain Cat5 cable is now harder to get and often more expensive than
Cat5e cable. Therefore it is quite likely that you might see a crossover
cable made from Cat5e cable.

On a peripheral subject, is it possible to connect two Gigabit cards
using a crossover cable in the same way as 100Mbit cards? I might afford
two gigabit cards but a gigabit switch is probably excessive for a home
network.

Although I have only used gigabit at work and always with a switch, AIUI
you just connect them with a straight CAT5E cable and they work it out
themselves (as some 100Mb equipment does). Gigabit uses all 8 wires
so I do not think a normal crossover cable will work. Ensure the cards are
set to auto-negotiation.

BTW I find 100Mb perfectly adequate for a home network.

Oh it's perfectly adequate, and I'm sure I will continue to think so
until I install the first gigabit link. I want to link two servers and
it's not significantly more expensive to do it with gigabit cards.

This is exactly the reason why we only supply Cat5e / Cat6. If you want
a crossover cable, we will happily supply you one to Cat5e spec. We
wouldn't recommend the use of Cat5 in any new network deployment now
anyway, as when the decision is made to upgrade it will all need
replacing. Go with Cat5e.
