10 I ICT TODAY • Performance: the applications are generally designed for the standard 100 m channel, but there are multiple grey areas where shorter links allow higher performance. The first standardized application for this was 10GBase-T. Although designed for Cat 6A, it could function on Cat 6 for limited distances depending on the quality of products and installation methods implemented. More recently, 2.5GBase-T and 5GBase-T both have similar testing methods to verify possible compliance on existing Cat 5e and Cat 6 for limited distances. And the latest Cat 8, although designed for data centers, could find a place in a commercial environment with a possible 25 Gb/s up to 50 m as shown in Figure 3. With increased cabling, PoE, and better performing topologies, the traditional star topology is beginning to reach its limits.
