Notice
- 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.
