Abstract

This article describes a plenum cable assembly in which a marking tape carrying identification indicia is embedded under a see-through TEFLON* coating. An external viewer can read the indicia easily and identify the cable. The drawing shows a cross-section and side view of the subject cable. Each functional portion of the cable is identified by appropriate labeling. The plenum cable assembly is comprised of a bundle of signal-carrying conductors identified in the drawing as ECL (Establishment Communications Link) cable internals. The first protective layer, preferably of black ceramic or glass tape, is disposed about the conductors. The marking tape is next disposed on the black ceramic layer. Preferably, the tape is disposed to run along the longitudinal axis of the cable.

A layer of thin material, such as clear FEP (fluorinated ethylene propylene) or ETFE (ethylene-tetrafluoro ethylene), is next disposed over the tape. * Trademark of E.I. du Pont de Nemours & Co.
