Structured Cabling is manufactured and installed to strict international performance standards, Your assurance that an investment in Structured Cabling today is one that will last well into the future.

The next level in the cabling hierarchy is Category 6 (ANSI/TIA/EIA-568-B.2-1), which was ratified by the TIA/EIA. CAT6 provides higher performance than CAT5e and features more stringent specifications for crosstalk and system noise. 

The quality of the data transmission depends upon the performance of the components  of the channel. So to transmit according to CAT6 specs, jacks, patch cables, patch panels, cross-connects, and cabling must all meet CAT6 standards. 

(The channel basically includes everything from the wallplate to the wiring closet.) The CAT6 components are tested individually, and they are also tested together for performance.

There are three main cabling standards: 

EIA/TIA 568A   This is the American standard and  was the first to be published (1991). 

ISO/IEC 11801  The International standard for structured cabling systems. 

CENELEC EN 50173  The European cabling standard  (the British version is BS EN 50173).
