Enhanced Category 5 is now the MINIMUM performance category recommended by the TIA for data communications.
Consider this: Our enhanced system gives you an additional 6.8 dB headroom over Cat 5e for NEXT at 100 MHz. Your equipment hears less than one-quarter of the crosstalk permitted by Category 5. Enhanced Category 5e cable even provides low power sum crosstalk and low skew. Both of these parameters are important for applications such as 1000BASE-T and other future applications which may deploy multi-pair transmissions.
