ISO/IEC ClassEa

3013AKIC6AI

TIA Cat 6A channel ≠ ISO ClassEa channel! Everybody is talking about Cat 6A nowadays. But even the name “Cat 6A” has different definition on transmission performance. Just bear in mind that ISO/IEC 11801 Ed. 2.2 Cat 6A (a.k.a. Class Ea) is the premium choice because it requires 1.8dB stricter at 500MHz than TIA-568.2-D Cat 6A does when it comes to channel performance. The patented US 9391405 B1 design features Inductance-offset technique to minimize the disturbance caused by Feed-Through connection. Made in Taiwan 4PPoE Compliant US 9391405 B1 Patented
Category 6A

3013AKIC6A

ANSI/TIA-568.2-D Cat 6A channel performance supports all kinds of inter-connection or cross-connection you may possibly encounter on the sites. The patented US 9391405 B1 design features Inductance-offset technique to minimize the disturbance caused by Feed-Through connection. Made in Taiwan 4PPoE Compliant US 9391405 B1 Patented
