  • a length of 2 mm wide electroluminescent tape was laminated to a D-shaped jacketed optical fiber cable.
  • a transparent protective sleeve was extruded around the outside of the laminated electroluminescent cable to protect the electroluminescent structure and ensure that it would remain attached to the cable.
  • Connectorization of the terminal ends with an FC style connector yielded an electroluminescent fiber optic patch cord.
  • Power was supplied to the electroluminescent fiber optic patch cord producing a patterned illumination along the patch cord's entire length matching the coated pattern of the electroluminescent layer.
  • the sample being measured was placed on a nonconductive surface.
  • a test probe similar to that described in MIL-G-83528 was placed on the sample such a manner that the weight of the test probe is uniformly distributed on the part or test sample. The entire width of the part was places in contact with each electrode. After a 30-second
  • Additional samples have been prepared using a 25 ⁇ PET protective layer as the base layer for the multilayer electroluminescent structure. Also, several samples were prepared to look at the effects of the thickness of the first electrode on key electrode properties (i.e. surface resistance of the ITO layer). In one sample, a surface resistance of about 10 ohm/sqr was achieved with a 100 nm thick coating of ITO glass on the protective layer. However, if the ITO glass layer gets too thick, the mechanical properties of the first electrode are degraded (e.g. the material can become brittle and result in delamination from the protective layer).
  • the multilayer electroluminescent structure Because of the thinness of the multilayer electroluminescent structure, there is a minimal change to the shape and relative size of any communication cable to which it is applied. In addition, the flexibility of the multilayer electroluminescent tape structure will have a minimal impact on the handleability of the resulting electroluminescent cable.
