Making Cables

Posted on November 21, 2007November 21, 2007 by Lori

Tools of the trade!

 You will need to have patch cables, crossover cables, and rollover cables in your networking toolkit.

Use the EIA/TIA Standards for your ends:

568A

White/Green    Green    White/Orange    Blue    White/Blue     Orange  White/Brown    Brown

568B

White/Orange    Orange    White/Green    Blue    White/Blue    Green    White/Brown    Brown

** Note colors are read with the clip of the RJ-45 connector on the bottom.

Patch Cable (straight through) – make both ends the same (we use 568B configuration)

Crossover Cable – make one end 568A and one end 568B

Rollover Cable – use the ribbon cable and make ends opposite.  To check before crimping, place both ends together with the writing on the cable on the same side and the clips both down.  Make sure that they are opposite.

IMPORTANT: You must crimp the ends before testing

When testing with the Fluke 620 LAN Cablemeter meant to test patch cables, your patch/straight through cables should say Pass and give you the length.

When testing a crossover cable with the Fluke 620 LAN Cablemeter you will get a miswire with a wiremap of:

12 36 45 78

36 12 45 78

When testing the rollover with the Fluke 620 LAN Cablemeter, you will get a Split Pair error with the following wire map:

12 36 45 78

87 63 54 21
