Chapter 1: Specifications
Table 1-1. CATx interconnect cable.
Cable Type Description
CATx solid-core 24 AWG cable
This S/UTP (CAT5e) cable confoms to EIA/TIA-568-B.
Uses four pairs of 24 AWG wires. Connects according
to EIA/TIA-568-B (1000BASE-T).
CATx solid-core 26/8 AWG cable
This S/UTP (CAT5e) cable confoms to EIA/TIA-568-B.
Uses four pairs of 26/8 AWG wires. Connects according
to EIA/TIA-568-B (1000BASE-T).
NOTE: You can use use type 26/8 AWG flexible cables (patch cables), but the
maximum possible extension distance is cut in half.
