Cable shielding, (or screening), can be composed of a metallic braid, or metallic or polyester foil. The shielding can be either wrapped around all 4 pairs of twisted pair cable, just the individual conductor pairs, or both the entire cable and individual pairs. In a shielded product code, the letters preceding the slash are equivalent to the shielding on the whole cable; the code after the slash is equivalent to the shielding for the individual pairs. For example:
As a guide, if you have motors or generators placed next to network cables, EMI and RFI can reek havoc with data transmission on a copper cable. This will result in data errors, and quite possibly downtime. In order to wipe out EMI/RFI interference, you will need to go for shielded cables and connectors.
As you can see from the list below, there are fundamentally two types of cable shields: braided and foil. Which option you plump for will depend on your application.
Here is a glossary of terms to help you decode cable shielding:
Designed for applications where standard patch cables would fail, these exclusive ultra-flexible cable assemblies are rated to 10 million flex-cycles at 1.82" (46.4mm) for continuous motion and automation applications.
The major benefit of using an antenna array over a single Omni directional antenna is that the antenna array provides radiation patterns that a single Omni antenna would not. In most cases, antenna arrays provide greater coverage than a single Omni antenna could.
As our climate becomes more extreme, there is an ever greater need to ensure that your wired and wireless communications equipment can stand up to the elements. If you are thinking about getting stronger protection for your equipment, you may find the following step by step guide useful.
