1. All transmission distances are measured using Belden 1583A CAT-5e 125MHz LAN 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 LAN cables, the type of video
sources, and the type of display. The testing result shows solid LAN cables (usually in bulk cable
300m or 1000ft form) can transmit a lot longer signals than stranded LAN cables (usually in patch
cord form). Shielded STP cables are better suit than unshielded UTP cables. A solid UTP CAT5e cable
shows longer transmission length than stranded STP CAT6 cable. For long extension users, solid
cables are your only choice.
3. To reduce the interference among the unshielded twisted pairs of wires in LAN cable, you
can use shielded LAN cables to improve EMI problems, which is worsen in long transmission.
4. Because the quality of the LAN cables has the major effects in how long transmission
distance will be made and how good is the received display, the actual transmission length is subject
to your LAN cables. For resolution greater than 1080i or 1280x1024, a CAT-6 cable is recommended.
