Qual é a diferença entre o cabeamento Ethernet Cat 6 e Cat 6e?
Não há um padrão para o cabo Cat 6e, portanto, não pode ser comparado ao cabo Cat 6 (para o qual há um padrão).
Existem padrões Cat 6 / Classe E e Cat 6a / Classe Ea (talvez você quis dizer um destes)? Veja abaixo e De-Mystifying Cabling Specifications De 5e a 7A para mais informações.

Cabo da categoria 6
Following the finalization of Cat 6, a number of manufacturers began offering "Category 6e" cables as an enhancement to the Category 6 standard—presumably naming it after Category 5e. However, no legitimate Category 6e standard exists, and Cat 6e is not a recognized standard by the Telecommunications Industry Association.
While all Cat 6e cables presumably meet Category 6 standards, the actual increase in transfer speeds and the maximum cable length can vary from manufacturer to manufacturer owing to the lack of a recognized industry standard.

Category 6/Class E
Category 6/class E cabling delivers double the signal-to noise margin (attenuation-to-crosstalk margin is positive to 200 MHz) of category 5e/class D cabling and provides the performance headroom desired by end-users to ensure that their cabling plant can withstand the rigors of the cabling environment and still support 1000BASE-T when it comes time for an application upgrade.
The category 6/class E cabling specification development process also brought to light the need to limit the conversion of differential mode signals to common mode signals and vice versa through the characterization of component balance, resulting in cabling systems with improved electromagnetic compatibility (EMC) performance.
Category 6A/Class EA
Category 6A/class EA cabling requirements were developed to address the extended frequency bandwidth and alien crosstalk headroom required to support 10GBASE-T over 100 meters of cabling containing up to four-connectors.
Category 6A/class EA cabling delivers positive signal-to-alien crosstalk margin up to 500 MHz and is recommended as the minimum grade of cabling capable of withstanding the rigors of the cabling environment and supporting 10GBASE-T when it is time for an application upgrade. Balance requirements for channels and permanent links are also specified for the first time, thereby ensuring better electromagnetic compatibility (EMC) performance than any previous generation of cabling.
