What is Patch cord bending radius?
A28:Patch-cord bend radius as stated in TIA/EIA-568-A document section 10.6.3.2,shall not be less than four times the cable diameter for horizontal cable.” This applies to termination on the back of the patch panel and outlet location where the horizontal cables terminate and bend-radius stability can occur due to securing the cables in place by tie wraps or other means, but at the front of the patch panel or work area location patch-cords may be in a state of flux from moves, adds, or changes and securing of patch. cords become impartial in real life. While the standards do not address the bend radius of patch cords, neither do they advocate the kinking of patch cords, which can lead to signal degradation in copper and broken glass in fiber patch cords.
