Flexible data cable as information carrier

A data cable is a multi-core cable used for simple transmission of data and information. It is important that the information moves securely from the sender to the receiver. To ensure that this happens, there are special shielding requirements.  igus data cables are used wherever large amounts of data must be safely transmitted in motion. They are usually shielded and carry a wide variety of application signals. Their cores are very thin and have coloured insulation to distinguish them. In the past, these cables were used much more frequently – they are gradually being replaced by bus cables in applications. Of course, they still have their uses, and our customers often deploy them. They are an inexpensive solution for transmitting simple data and are available in various mechanical and electrical designs. The cables are available in three different jacket materials. This selection provides additional savings opportunities.
 

Star quad and near end crosstalk

What is a star quad structure anyway?

In a four-core cable, this structure determines the arrangement of the cores within the cable. There are usually coloured cores in the data cable, but here we use the designation 1-4 to simplify our explanation. In a conventional cable, the cores are marked clockwise. This means that, e.g., 1 is at the top left, 2 at the top right, 3 at the bottom right, and finally 4 at the bottom left. In star quad stranding, the core order in the cable is 1, 3, 2, 4. The pairs 1-2 and 3-4 are perpendicular to each other in their magnetic fields to avoid signal overlap. This avoids near end crosstalk. You can find out more about this in our blog.
