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.
