EoVDSL Wiring
VDSL operates over 2-wire Category 3 (CAT-3) or higher twisted-pair wiring. Other
twisted-pair wiring with similar characteristics may work, although the performance
will vary depending on the cable characteristics and distance.
When wiring EoVDSL ports, note the following:
• EoVDSL ports are designed to be used on private communications lines for
point-to-point connections and are not to be connected to the Public Switched
Telephone Network (PSTN).
• To reduce the risk of fire, use only #26 AWG or larger telecommunication line
cord.
• Twisted-pairs are an effective way of reducing both magnetic and capacitive
interference, as they reduce the magnetic loop area to nearly zero and maintain
a consistent distribution of capacitances to both ground and other sources.
Therefore, make sure twisting is consistent throughout the cable length.
