NOTICE
1. All transmission distances are measured using Belden 1583A CAT5e 125MHz Solid UTP cable
and ASTRODESIGN Video Signal Generator VG-859C. The transmission distance is defined as the
distance between the video source and the VGA display.
2. The transmission length is largely affected by the type of CAT5/6 cables, the type of VGA sources,
and the type of VGA display. The testing result shows solid UTP cables (usually in the form of
300m or 1,000ft bulk cables) can transmit a lot longer signals than stranded UTP cables (usually
in the form of fixed length patch cords). Shielded STP cables are better suited than unshielded
UTP cables. A solid UTP CAT5e cable shows longer transmission range than stranded STP CAT6
cable. For long extension users, solid UTP/STP cables are the only viable choice.
3. To reduce the interference among the unshielded twisted pairs of wires in UTP cable, you can
use shielded STP cables to improve EMI problems, which is worsen in long transmission.
4. Because the quality of the CAT5/6 cables has the major effect on how long the transmission limit
can achieve and how good is the received picture quality, the actual transmission range is
subject to one’s choice of CAT5/6 cables. For desired resolutions greater than 1080i or
1280x1024, a Cat-6 cable is recommended.
