SPECIFICATIONS
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.
