Always use the Random Lay mantra; “Random lay in the bundle and tray © For Cat 6 cable and Cat 6A “ P. Meijer An existing Class E channel using Category 6 components will have its performance improved to a level where it may comfortably carry 10GBE applications by applying where possible a combination of some of the following; At the Floor Distributor Remove cable ties from bundles in the telecommunication room racks, cabinets and pathways. The majority of ANEXT occurs in the first 15 meters from the patch panel or termination modules where the signal strength is greatest. Apply cable bundle fasteners only where necessary to mechanically support the cables and at both sides of a change in vertical direction of the cabling. Use only ‘hook & loop’ type fasteners, at least 12 mm wide, or approved elastic bundle fasteners. Do not use nylon ties or ‘zip ties’. Upgrade patch cords to CopperTen Cat 6A patch cords. Use longer patch cords to provide more ANEXT noise attenuation, but do not exceed the allowable Channel Insertion Loss. The minimum patch cord length must be metres. 3 metre CopperTen patch cords give even better ANEXT mitigation. Place the patch cords in Random Lay so that there is less chance of coupling from parallel runs. Replace existing Category 6 patch panels with polymer Category 6A staggered-socket patch panels. This increases the separation between outlets and minimises coupling. Where patch panel replacement is not possible, use non-adjacent sockets and non- adjacent channels for the 10GBE. Use patch cord management systems like the ADC Glide Managers that allow room and facility for Random Lay and/or patch cord separation. Change from a cross-connect to an interconnect cabling arrangement. The unused cross-connect panels or modules are .
