6. Ethernet Cables
The performance of a CAT6A rated link is dependent on the cabling, connectors, mated
connections and hardware components that make up the link.
The PoE5 data path passes 10GBASE-T traffic from each test port to the adjacent test port
(ports 1-2, 3-4, etc.). The data path connections are made through magnetics and signal relays
for compatibility with Phy-based cable diagnostics. When passing 10GBASE-T traffic
through the PoE5 data path, it is important to consider the type of cable, plugs and jacks used
as part of that link.
The PoE5 data paths are all tested to the TIA CAT6A permanent link test limit using the
DSX-5000 and the DSX-PLA004 permanent link adapters as shown in Figure 1 below. The
permanent link consists of two 40-meter CAT6A cables. Each 40-meter length of cable
consists of a plug mated to the test port, and a jack mated to the DSX-PLA004 permanent
link adapter. The cable and connector combination shown in Figure 1 provided the best
performance.
