Abstract

A communications apparatus for transmitting various communication signals is described. The communications apparatus contains at least two conductors or fibers where the first conductor or fiber comprises a first color and the second conductor or fiber comprises a second color having a lighter tint of the first color. In an embodiment of the invention, using this scheme of a dark shade of a color for one of the conductors or fibers and a lighter color for the other conductor or fiber, the conductors or fibers can always be identified as a pair even after they have been untwisted (and even when the remaining pairs in the cable become untwisted). The invention does not use bandmarks or stripes in the insulation of the second conductor, thereby avoiding the accompanying limitations associated with bandmarks and stripes.

Claims

1. A method of making a communications apparatus, comprising:

providing a first conductor or fiber and second conductor or fiber; and

providing the first conductor or fiber with a first color and a second conductor or fiber with a second color having a lighter tint of the first color.

2. The method of claim 1, including providing the first and second conductors or fibers with a first insulation and a second insulation, respectively.

3. The method of claim 2, wherein the material for the first and second insulation is a polymeric resin mixture and the first and second insulation is provided on the first and second conductors or fibers by an extrusion process.

4. The method of claim 3, including providing the first insulation with the first color and the second insulation with a second color.

5. The method of claim 4, including providing the first insulation with the first color by mixing the material for the insulation with a dye or pigment and including providing the second insulation with the second color by mixing the material for the insulation with a dye or pigment.

6. The method of claim 1, wherein the first and second conductors or fibers are a twisted pair.

7. The method of claim 1, wherein the difference between the first and second colors can be distinguished by the naked eye.
