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
Category 6

3013AKIC6S

Considerations for running 802.3bz 5GBASE-T to support higher data rate of wireless AP would push the required bandwidths to 312MHz, well above the 250MHz specification of ANSI/TIA 568.2-D and ISO/IEC-11801 Category 6. HCI Unshielded Super Cat 6 keystone coupler go beyond extended bandwidth for up to 350MHz. The patented US 9391405 B1 design features Inductance-offset technique to minimize the disturbance caused by Feed-Through connection. Compact structure allows loading into 48-port in 1U high density patch panels and 6-port gang frames. Made in Taiwan 4PPoE Compliant US 9391405 B1 Patented
