Which feature is common in Direct Burial STP cables?

Direct Burial STP (Shielded Twisted Pair) cables are specifically designed to be installed underground, where they may be exposed to moisture and environmental conditions. One of the common features that makes them suitable for this application is the presence of gel or other water-resistant materials contained within the cable. This gel helps to repel water and prevents moisture from penetrating the cable, which could otherwise damage the internal wires and lead to signal degradation or loss.

Due to the cable's intended use outdoors and underground, it must withstand various environmental factors. The gel serves as a protective layer, ensuring that the cable remains functional even in damp or wet conditions, which is crucial for maintaining network integrity in outdoor installations.
