Ethernet Cables
Cat 6 vs. Cat 8.1
Comparing 2 standards across 15 specifications. 15 key differences identified.
Comparing:
Cat 6
Cat 8.1
Category 6 (Cat 6) is a twisted-pair Ethernet cable standard defined in ANSI/TIA-568-B.2-1. Rated up to 250 MHz, it supports 1 Gbps at 100 meters and 10 Gbps (10GBASE-T) up to 55 meters in low-crosstalk environments, featuring tighter pair twists and a central longitudinal spline separator.
Category 8.1 (Cat 8.1) is an Ethernet cabling standard defined in ANSI/TIA-568-C.2-1 (Category 8) and ISO/IEC 11801 Class I. Operating at 2000 MHz (2 GHz), it supports 25GBASE-T and 40GBASE-T data rates over a 30-meter channel using backward-compatible 8P8C (RJ45) shielded connectors.
