Recommendations for the twisted pair cable
The transmission of all signals of the DVIVision system is carried out through one
twisted pair cable (category 5e or better).
The data transmission is reliable over a distance of at least 100 metres using a regu-
lar standard twisted pair cable (category 5e or better). The distance that can actually
be achieved depends on the quality of the used cable. High-quality S-STP cables
with an AWG22 wire gauge coding can bridge a distance of up to 140 metres. Patch
cables with an AWG26 wire gauge coding can only bridge a maximum of 80
metres.
To ensure reliable operation even in environments with interference, installation
cables with at least AWG24 coding have to be used for lengths over 80 metres.
The following cables achieved the best results during test operation:

up to 140 metres: Kerpen MegaLine G12-150 S/F AWG22

up to 100 metres: G&D K-C5-HR (see
Order numbers
on page 45)

up to 80 metres: Dätwyler Uninet flex 4P, AWG26, S-STP
The connection of several segments using patch panels and connection ports is
permitted. However, connections through active network components such as
network switches, hubs or repeaters are not permitted.
Wire gauge Cable type Category Recommendation
AWG22 Installation 5e, 6 or 7 up to 140 m
AWG23 Installation 5e, 6 or 7 up to 130 m
AWG24 Installation 5e, 6 or 7 up to 120 m
AWG26/27 Patch cable 5e, 6 or 7 up to 80 m

The lengths that are mentioned in the table above must be interpreted as the sum
of all segments between the devices.
