This shielded snagless Cat6 cable is perfect for use with our HDBaseT 
Products or with any other application where long length shielded cable is 
required. This cable is optimized for superior performance in noisy 
environments and is designed to handle bandwidth-intensive applications. 
This cable is designed to meet Cat6 TIA/EIA and ISO/IEC standards for patch 
cable performance. Each individual pair is bonded together to help maintain 
the twist-spacing throughout the cable right up to the termination point. 
The cable design minimizes Near-End Crosstalk (NEXT) levels and features 
high quality solid conductors, full cable shielding and is terminated with 
a snagless boot & shielded plug. The combination of the shielded plug, 
shielded cable, snagless boot and solid conductors provides superior 
performance over standard stranded conductor patch cables when used with 
HDBaseT solutions.
