Communication cable comprising electrically discontinuous shield having nonmetallic appearance
View Patent ↗A tape can comprise a dielectric film that has a pattern of electrically conductive areas adhering thereto. The conductive areas can be electrically isolated from one another. The tape can utilize means to obscure the metallic finish and can contain indicators to deter installers from grounding the tape at either end. The tape can be wrapped around one or more conductors, such as wires that transmit data, to provide electrical or electromagnetic shielding for the conductors. The resulting cable can have a shield that is electrically discontinuous between opposite ends of the cable.
1. A communication cable comprising:
a plurality of individually insulated electrical conductors, for transmitting communication signals between a first end and a second end of the communication cable; and
an outer jacket covering the plurality of individually insulated electrical conductors and a elongated object that extends between the first end and the second end of the communication cable,
wherein the elongated object comprises:
a substrate comprising electrical insulation;
patches, comprising electrically conductive material, that are attached to the substrate and that are operable to shield at least one of the plurality of individually insulated electrical conductors from interference, wherein a patch at the first end of the communication cable is electrically isolated from a patch at the second end of the communication cable; and
indicia differentiating the elongated object from an electrically continuous elongated object to an installer of the communication cable.
2. The communication cable of claim 1 , wherein the elongated object comprises a tape.
3. The communication cable of claim 1 , wherein the substrate comprises a slender strip of dielectric material.
4. The communication cable of claim 1 , wherein a plurality of the patches are about 1.5 to 2 inches in length.
5. The communication cable of claim 1 , wherein a plurality of the patches are between 1.5 and 2 inches in length.
6. The communication cable of claim 1 , wherein a plurality of the patches are about 4 to 5 centimeters in length.
7. The communication cable of claim 1 , wherein a plurality of the patches are between 4 and 5 centimeters in length.
8. A communication cable comprising:
a plurality of individually insulated electrical conductors, for transmitting communication signals between a first end and a second end of the communication cable;
a flexible member running alongside the plurality of individually insulated electrical conductors and extending between the first end and the second end of the communication cable; and
an outer jacket covering the plurality of individually insulated electrical conductors and the flexible member,
wherein the flexible member comprises:
patches, comprising electrically conductive material, that are operable to shield at least two of the plurality of individually insulated electrical conductors from interference, wherein a patch at the first end of the communication cable is electrically isolated from a patch at the second end of the communication cable; and
indicia differentiating the flexible member from an electrically continuous flexible member to a cable installer.
9. The communication cable of claim 8 , wherein the flexible member is a tape.
10. The communication cable of claim 8 , wherein the flexible member comprises a ribbon of dielectric material to which the patches adhere.
11. The communication cable of claim 8 , wherein the indicia comprises a message informing the installer that the flexible member should remain ungrounded.
12. The communication cable of claim 8 , wherein the indicia comprises a material that is operable to obscure the electrically conductive material from the installer.
13. The communication cable of claim 8 , wherein the indicia comprises a notification intended for receipt by the installer.
14. The communication cable of claim 8 , wherein the flexible member appears substantially non-reflective as viewed by the installer.
15. The communication cable of claim 8 , wherein a plurality of the patches are about 1.5 to 2 inches in length.
16. The communication cable of claim 8 , wherein a plurality of the patches are between 1.5 and 2 inches in length.
17. The communication cable of claim 8 , wherein a plurality of the patches are about 4 to 5 centimeters in length.
18. The communication cable of claim 8 , wherein a plurality of the patches are between 4 and 5 centimeters in length.
