hold the RJ45 connector with the clip pointing away from you and identify the colour order of the wires inside the RJ45 connector this is a Crossover cables reverse view of the RJ45 connector this is a straight through cables reverse view of the RJ45 connector so the topographical view of an Ethernet cable would look like this cables under 30M are usually stranded (multi core) however cables over 30M are usually solid core but this isn't written in stone, some people have successfully used stranded cable for over 100M, solid core cables are also used in a permanent installation (inside walls or under floors) Edit:Tips A straight-thru cable has identical ends A crossover cable has different ends A straight-thru is used as a patch cables in Ethernet connections A crossover is used to connect two Ethernet devices without a hub or for connecting two hubs A crossover has one end with the Orange set of wires switched with the Green set Odd numbered pins are always striped, even numbered pins are always solid coloured Looking at the RJ-45 with the clip facing away from you, Brown is always on the right, and pin 1 is on the left No more than 1/2" of the Ethernet cable should be untwisted otherwise it will be susceptible to crosstalk Do not deform, do not bend, do not stretch, do not staple, do not run parallel with power cables, and do not run Ethernet cables near noise inducing components cable types CAT-5 is rated up to 100M CAT-5e is rated up to 350M CAT-6 and CAT6e is rated up to 550M or 1000M depending on your source CAT-7 is supposedly rated up to 700M or presumably it will function upto 1000M Thanks to Swanen for his Input Edit: Crossover cables are usually in UK, however, as AT said straight thru cabeles are more common in North America
no, because crossover is T568A to T568B but straight through is T568B to T568B[ot]look at the colour of the wires in the left connector closely, the straight through (T568B to T568B) pin 1 is stripped / semi green pin 2 is green pin 3 is semi green pin 4 is blue pin 5 is semi blue pin 6 is green pin 7 is semi brown pin 8 is brown whereas crossover is: (T568A to T568B) pin 1 is semi orange pin 2 is orange pin 3 is semi orange pin 4 is blue pin 5 is semi blue pin 6 is orange pin 7 is semi brown pin 8 is brown BTW: and i'm partially colour blind[/ot] Edit: thanks anyway :good: RHochstenbach, i need people like you, to make sure i'm correct :beer:
Well, my confusion came in when i had to click on the pictures and i wasn't sure of what i was looking at. Maybe you should have labels on the pictures, or just have full sized pictures and not thumbnails. Or just link to the pictures instead. Some other considerations for pictures. http://ftp.ipsyn.net/pub/mirrors/cabling/T568B_scheme_opt.jpg But this is just my opinion, i just thought those were kinda confusing pictures. Anyways, it looks nice, good job.
Just an FYI on this thread, at least in north America, most companies use the 'B' standard for wiring.
