Digital signal processing is all about production and transmission of data with little or no interference. The signal interference may originate from within or around the transmission line. Getting to know much of your working environment will help you decide on whether to use shielded or unshielded cable.
The primary causes of ATX are line voltage interference and in-wall cables installation. It is, therefore, wise for the electrical line to cross with the low voltage communication cables at an angle of 90 degrees.
Just like all other communication cables, Ethernet cables have an antenna like the cross-section. The impact of the Alien Cross-Talk (ATX) becomes a major issue at a higher frequency signal transmission. However while using cat 5e and cat6 the ATX is insignificant owing to the low-frequency data transmitted by these types of cables
Crosstalk cancellation technique is only employed in the near or far end of the cables for a known source of interference.
Whether it is the near end cross talk or the foreign interference that causes a primary concern will further determine the choice the cable to be used during installation. To reduce ATX, one should opt for a wholesome shielded cable while NEXT is controlled by a cable with individual twisted pair further shielded.
Although all the shields are electrically bonded, proper grounding is crucial; consider using appropriate couplers and jacks that allow natural grounding.
Choice for industrial environments and healthcare facilities
Cat 6a STP has a significant advantage over a Cat 6a UTP. The shield around the cable put offs radio frequency interference from reaching the twisted pair. Hence STP convenient for places dominated by types of machinery.
Okay. It’s true that the expense of a shielded Ethernet cable per foot is slightly higher than UTP. However, when you consider their excellent performance and shorter testing time, it may be less costly regarding overall cost and installation time.
Future proof communication cables
With the changing technology in the communication sector, it is wise to install a network that will not require the frequent upgrade. Consequently it advisable to use transmission cables that supersedes the current 10 GB/s transmission rate. STP, therefore, makes a good choice along this line of reasoning.
Both UTP and STP have almost equal installation time.
One does not need to discriminate shielded cables by installation time. This is because the new STP comes with easy to fix to die cast jacks; no elaborate steps during installation are necessary. The only caveat here is additional shorter time needed to detach the general shield from the cable.
Unlike UTP that requires a reasonable amount of time for the ATX testing process, STP needs no such trials.
No complicated bonding process for STP
There is the traditional belief that shielded cables require an elaborate grounding and bonding procedure. However, this is baseless. However, just like the grounding of all other equipment, STP is no different, provided the STP’s shield is fixed to the patch panel at the end.
But in overall, the quality of the signal to be received at the end of transmission depends on to a large extent the quality of the data fed in initially.
