Cables should be kept at a distance of at least 12 inches from power cables. In an environment prone to high
EMI, it is best to use shielded cables. Most Cat5e cables are unshielded, which makes them more exible,
durable and inexpensive. But they are also more suscepble to EMI. If using unshielded cables, keep them
away from any source of EMI such as other cables, transformers and light xtures. In high RF environments,
it is best to use shielded cables.
The same applies to shielded connectors. In a shielded connector, the signal pins are surrounded by a metal
shield and further reduce electromagnec interference. Shielded connectors provide a beer t and therefore
beer performance.
HDBaseT delivers the 5Play feature set over 100m/328. One of the factors that aects distance is the quality
of the cable used, the working environment, and the video resoluon expected. Higher quality cable will
keep the signal beer than low quality cable over distances. A noise-free environment will deliver beer
performance over the distance than a noisy or EMI-prone environment. Some HDBaseT equipment allows for
Long Reach connecvity -150m/492- for lower resoluons of 720p.
If possible, avoid patch cords or cables altogether, as every connecon introduces losses in the transmission.
If absolutely necessary, make sure to use less than two per cable run and keep each less than ve meters
from the end.
One of the advantages of HDBaseT’s using of LAN cables os that they are easily eld terminated. That means
there is no need to pre-measure cables and bring all the set-up ready ahead of me, saving me & money.
Make sure to use proper equipment for terminaon, such as cable strippers, electrician scissors, and crimpers.
Alos, make sure that both ends of the cable are wired according to the same scheme, either T568A or T568B.
Never use both in the same installaon. It is also recommended to check with HDBaseT manufacturers which
scheme their products are opmized and equalized for, to take full advantage of the expected performance.
Tesng is crucial to guarantee both cable quality and signal integrity. Pre-tesng ca save hours and resources
from troubleshoong any issue ahead of me. During and aer installaon, a professional test equipment
will check connecons and transmission of the installed infrastructure, beyond broken or mismatched wires,
but also any hidden issues that may cause interference or loss of signal. Make sure to test every cable as it is
installed and terminated, to idenfy individual problems as the installaon goes.
Document and label all cabling components to facilitate any upgrades or expansions later, including
diagrams. Remove any abandoned cables to prevent accidents or re hazards. Avoid roung cables through
pipes and holes, which may limit addional future cable runs.
