Mechanical, Performance and Guaranteed Parameters

Guaranteed System Margin Guarantees (worst-case margins for specified channel lengths)

Insertion Loss: 2% margin guarantee
NEXT: 1 dB
PSNEXT: 2 dB
ACR-F (ELFEXT): 2 dB
ACRN: 3 dB
PSACRN: 3 dB
TCL: 1 dB
ELTCTL: 4 dB

Notes: Guaranteed margins apply at 20°C for 17–100 m channels (or 17–93 m when using 28 AWG patch cords) and apply when installed and tested by Leviton Network Solutions Certified Installers.

Extended Application Distances (selected from Table 1)

10BASE-T: up to 200 m (Type 1 PoE) / 125 m (Type 2+)
100BASE-TX: up to 140 m (Type 1) / 125 m (others)
2.5GBASE-T: 105 m (Type 1 and Type 2)
5GBASE-T: 100 m (all PoE types shown)

Installation note: Use of 28 AWG patch cords in a channel over 100 m is not allowed; channels >100 m are application-specific.
