when using the new 1000base-t standard, the limitations of cable installations and the steps necessary to ensure optimum performance must be considered.the most important components in your cabling system are patch panel connections, twists of the pairs at connector transition points, the jacket around the twisted-pair cable, bundling of multiple pairs on horizontal runs and punch down blocks. all of these factors affect the performance of 1000base-t technology if not correctly implemented.the following sections are designed to act as a guide to correct cabling for 1000base-t.
