Technically there is no difference nor have difference in performance.

Most of existing infrastructures are EIA/TIA 568B. If you are adding to existing infrastructure use same what you have now.

the only difference between two is :B use w/o and o for pin 1 & 2 and w/g & g for pin 3 & 6 , where A use w/g & g for pin 1 & 2 and w/o & o for pin 3 & 6.

thx,

As stated earlier, there is no performance difference. If you wire one end of the cable 568A and the other end 568B you then have a crossover cable.

all of the friends gave good advice and info but they left one thing out . NEVER MIX THE TWO in your structured cabling . As it grows you will have a chaotic situation at hand . Choose and follow one standart all the way.
