NOTICE
1. All HDMI over CAT5 transmission distances are measured using Belden CAT6A (625MHz), 4-Pair, U/UTP-
Unshielded, Riser-CMR, Premise Horizontal Cable, 23 AWG Solid Bare Copper Conductors, Polyolefin
Insulation, Patented Double-H spline, Ripcord, PVC Jacket using Quantum 980 signal HDMI Video Generator
Module Video Pattern Testing.
2. The transmission length is largely affected by the type of category cables, also the type of HDMI sources,
and the type of HDMI display. The testing result shows solid UTP cables (usually in the form of 300m or
1000ft bulk cable) can transmit a lot longer signals than stranded UTP cables (usually in the form of patch
cords). Shielded STP connectors are better suit than unshielded UTP connectors. 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. EIA/TIA-568-B termination (T568B) for category cables is recommended for better performance.
4. To reduce the interference among the unshielded twisted pairs of wires in category cable, you can use
shielded STP cables with shielded connector to improve EMI problems, which occurs in long transmission.
5. Because the quality of the category 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 category
cables. For resolution greater than 1080i or 1280x1024, a solid CAT6 cable is the only viable choice.
