1. All HDMI over CATx transmission distances are measured using Belden CAT6A (625MHz),

4-Pair,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 with Video Pattern Testing and shielded

ends.

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 CAT6A cable shows longer transmission length than solid UTP

CAT5E/6E cable.

3. EIA/TIA-568-B termination (T568B) for category cables is recommended.

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

poor wiring environments with unplanned cable runs situated away from EMI interference.

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 signal on the display, the actual transmission length

is subject to high quality category cables. For resolution greater than 1080i or 1280x1024, a

solid CAT6E 250MHz cable is the only viable choice.
