Description

PATCH CORD WITH A LIGHT PIPE
Cross-Reference to Related Applications
[0001] The present application claims priority to U.S. Patent Application Serial No. 60/829,584, filed October 16, 2006, entitled, "Patch Cord With a Light Pipe" and is incorporated herein by reference in its entirety. This application also incorporates by reference in its entirety U.S. Patent Application Serial No. 60/765,907, filed February 7, 2006 and entitled, "Smart Cable Provisioning for a Patch Cord Management System."
Technical Field
[0002] The present invention relates to network documentation and revision systems and more particularly relates to a system for using patch cables having indicators that can be illuminated to guide the installation and removal of the patch cables.
Background
[0003] Patch panels are used in communications networks as intermediate elements between horizontal cabling (to which endpoint devices such as computers and telephones are connected) and network switches. When physical connections between endpoint devices and network switches are moved, added, or changed, patch panels are the points at which technicians complete the required moves, additions, or changes of cabling within patch fields. It is important to keep track of changes that are made to patch cord connections within the patch field. Proper documentation of changes in the patch field assures that the routing of patch cords is always known and further assures that any future changes are completed correctly.
[0004] In interconnect network configurations, one patch panel is placed between the horizontal cabling and the network switch. In an interconnect configuration, the documentation of patch cord connections between the patch panel and the switch will provide the necessary documentation of connections between the switch and the horizontal cabling. It is desirable to have a patch cord management system that enables complete documentation of patch cord connections and that guides network installers as they make moves, adds, or changes to the patch cord connections. It is also desirable for a patch cord management system to have a minimal impact on existing networks. It is further desirable to have a patch cord that allows for the guided installation and removal of patch cords in interconnect network configurations.
Summary of the Invention
[0005] According to one embodiment of the present invention, a patch cord is provided with a light pipe. The light pipe is adapted to accept light at one end of the patch cord and to display the light at the opposite end of the patch cord.
[0006] According to one embodiment of the present invention, a patch cord is provided with a light pipe that accepts light at a patch panel end of the patch cord. The light pipe transmits the light down the length of the patch cord and displays the light at the opposite end of the patch cord, for example at a switch.
[0007] A patch cord according to the present invention may be provided with a light- accepting plug at one end of the patch cord and a light-emitting plug at the other end of the patch cord.
[0008] Systems and methods according to some embodiments of the present invention allow for the illumination of patch panel jacks and patch cord plugs to facilitate the installation and removal of patch cords in interconnect network configurations.

[0013] Fig. 5 is a side view of a patch cord plug plugged into a network switch. Detailed Description of Preferred Embodiments
[0014] The present invention is directed to a patch cord having a light pipe for guiding the installation and removal of the patch cord. Patch cords according to the present invention may be smart patch cords as shown and described in the U.S. Provisional Patent Application having serial number 60/765,907, entitled "Smart Cable Provisioning for a Patch Cord Management System."
[0015] Fig. 1 is a cutaway side view of a patch cord 10 installed between a patch panel 12 and a network switch 14 (for example, a CATALYST® 6509 switch manufactured by Cisco Systems, Inc.). The patch cord 10 has a light pipe 16 that accepts visible light from a light source 18 that is mounted on the patch panel 12. The light pipe 16 accepts the light at a patch panel plug 20 of the patch cable 10. The light pipe 16 transmits the light from the light source 18 along the length of the patch cord 10 to a switch plug 22 of the patch cord 10. In the embodiment shown in Fig. 1 , the light pipe 16 is provided with a bend 24 that reroutes the light to a display area 26 of the switch plug 22. The display area 26 is easily viewable by a technician. According to one embodiment of the present invention, the light source 18 is a light-emitting diode (LED), and the light pipe 16 comprises a plastic optical fiber. The bend 24 in the light pipe 16 may be formed by heating and bending the light pipe 16.
[0016] Fig. 2 shows a front view of a patch panel port 28. In one embodiment of the present invention, each patch panel port 28 is provided with a patch panel jack 30 and a light source 18. The light source 18 is positioned to align with a light input 31 of the patch panel plug 20 (as shown in Fig. 1 ).
[0017] Fig. 3 is a cross-sectional view of a patch cord 32 according to one embodiment of the present invention. A light pipe 16 as described above is provided within the patch cord 32. Twisted pairs of signal conductors 34a-34d are separated by a separator spline 36. Ninth and tenth wires 38a and 38b are also provided, and they may support the smart cable functionality shown and described in the above-referenced provisional patent application entitled, "Smart Cable Provisioning for a Patch Cord Management System." As further described in that application, the ninth and tenth wires 38a and 38b may be used in combination with a "pogo pin" probe switch 42 that is provided on the switch plug 22 (as shown in Figs. 4 and 5). An outer jacket 40 surrounds the patch cord assembly.
[0018] As described above with reference to Fig. 1 , patch cords according to some embodiments of the present invention are asymmetrical in that the two ends of the patch cords have different plugs. Further details of one embodiment of the switch plug 22 are shown in Figs. 4 and 5. Fig. 4 shows an end view of two switch plugs oriented for insertion into a high-density network switch. In such a switch, vertically neighboring plugs are inserted in an opposing over-under configuration. Projections 44 are provided to house the display area 26 and the probe switch 42 of the switch plug 22. To accommodate the opposing over-under configuration necessary in a high-density network switch, the projections 44 are offset from the centers of the switch plugs 22. As shown in Fig. 4, the projections 44 are preferably provided on the side of the switch plug 22 opposite a plug latch 46.
[0019] Fig. 5 shows a side view of a switch plug 22 inserted into a port of a network switch 14. The probe switch 42 is engaged upon insertion of the switch plug 22 into the network switch port. The dotted line in Fig. 5 illustrates the path of the light pipe 16 passing through a boot 48 and through the switch plug 22.
[0020] The principles of the present invention may be applied to other specific systems. In some embodiments, signal contacts of the plugs are configured to mate with RJ-45 jacks. However, patch cords according to other embodiments of the present invention are designed for use in optical communication networks or in other electrical communication networks that do not employ RJ-45 plugs and jacks. Further, multiple light pipes or light inputs may be provided to support more than one color of illumination to provide more guidance during installation, movement, or removal of a patch cord.
