Black Box Explains...Category 6.
Category 6 has more stringent specifications for crosstalk and system noise than CAT5e. For cabling to transmit according to CAT6 specs, it must be used in a complete channel solution with vendor-specific jacks, patch cords, and patch panels, and the cabling must be tuned correctly. GigaTrue™ is the channel solution offered by Black Box.
The minimum GigaTrue NEXT (Near-End Crosstalk) specification at 100 MHz is 41.8 dB, allowing for 1.9 dB of headroom above the CAT6 channel specification. In theory, a channel with headroom like this performs better than a channel that only meets the minimum requirements.
