A high-density multi-port-module patch panel system includes angled multi-port modules. The system accommodates a high density of cable connections, while also providing effective cable management without increasing the maintenance costs or sacrificing the network performance. The angled multi-port modules exert less stress on the connectors and portions of the cabling adjacent to the connectors. Further, the angled arrangement provides a neater arrangement, and better facilitates maintenance and service procedures by providing improved visibility of labeling surfaces.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention generally relates to a cable patch panel, and more particularly, to a high-density multi-port-module patch panel system for use in the telecommunications industry. 
     2. Description of the Background Art 
     In the telecommunications industry, use of cable patch panels with multi-port modules is rapidly growing. Although good cable management may not positively enhance network performance, poor cable management will increase the maintenance costs and indirectly detract from the network performance. 
     Due to limited space in telecommunication closets, there is a continuous need for maintaining a high-density cable patch panel to accommodate more cables such as electrical cables, telephone cables, network cables, fiber optics, etc. However, the conventional patch panel requires additional space for horizontal cable managers, which causes a lower port density for cable connections. 
     Therefore, there is a need in the art for a high-density cable patch panel, which can accommodate more cables while also providing an effective cable management without increasing the maintenance costs or sacrificing the network performance. 
     SUMMARY OF THE INVENTION 
     The present invention fulfills the aforementioned need in the art by providing a high-density multi-port module system. The high-density multi-port module system comprises a rack having a first rail and a second rail; a patch panel frame mounted on the rack; a first plurality of vertical multi-port modules juxtaposed in the patch panel frame at a first angle, relative to normal of the patch panel frame, toward the first rail of the rack; a second plurality of vertical multi-port modules juxtaposed in the patch panel frame at a second angle, relative to normal of the patch panel frame, toward the second rail of the rack; and a first vertical cable manager on the first rail of the rack and a second vertical cable manager on the second rail of the rack, the first and the second vertical cable managers holding cables connected to the first or the second plurality of multi-port modules, respectively.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       FIG. 1  is a perspective view of the high-density multi-port-module patch panel system  100  in accordance with one embodiment of the present invention. The high-density multi-port-module patch panel system  100  comprises a rack  112  having a first or right rail  112   a  and a second or left rail  112   b  and a patch panel frame  102  mounted on the rack  112 . The patch panel frame  102  includes the first plurality of vertical multi-port modules  104  and the second plurality of vertical multi-port modules  106 . However, it should be noted that the multi-port modules  104  and  106  could be horizontal multi-port modules. The patch panel frame  102  has a front face  102   a , which resides in a plane that is substantially parallel with a plane defined by the right rail  112   a  and the left rail  112   b  of the rack  112 . 
     In the embodiment shown in  FIG. 1 , the patch panel frame  102  is a two-tier patch panel frame, i.e., the frame includes two rows of multi-port modules  104  and  106 . However, it should be noted that the patch panel frame  102  could be a one-tier patch panel frame (i.e., only one row of multi-port modules  104  and  106 ) to accommodate less modules. Alternatively, the patch panel frame  102  could have more than two rows of multi-port modules  104  and  106 . Moreover, it should be noted that although the frame may have room for two or more rows of multi-port modules that only one row may be populated. One or more rows may be left empty and accommodate further expansion when additional multi-ports are required. 
     The high-density multi-port-module patch panel system  100  also comprises a first vertical cable manager  108  on the right rail  112   a  of the rack  112  and a second vertical cable manager  110  on the left rail  112   b  of the rack  112 . The first and the second vertical cable managers  108  and  110  hold cables  114  connected to the first and the second plurality of multi-port modules  104  and  106 , respectively. In the embodiment shown in  FIG. 1 , the vertical cable managers are 4-inch CPI cable distribution spools. If only a one-tier patch panel frame (i.e., only one row of multi-port modules) is mounted on the rack  112 , one spool on each side of the rack  112  would be enough to hold the cables  114 . In a two-tier patch panel frame, two spools on each side of the rack  112  are preferred to avoid overloading of cables on an individual spool. 
       FIG. 2  is a close-up perspective view of the high-density patch panel with multi-port modules of  FIG. 1 , removed from the rack  112 . In one embodiment of the present invention, the patch panel frame  102  is made of a lightweight steel sheet, and the patch panel frame  102  includes a steel vertical reinforcement bar  102   b  to provide stiffening and structural integrity. The first plurality of multi-port modules  104  are juxtaposed in the patch panel frame  102  to the right of the reinforcement bar  102   b . The ports of the first plurality of multi-port modules  104  are directed at a first angle, relative to a normal line extending away from the front face  102   a , toward the right rail  112   a  of the rack  112 . The second plurality of multi-port modules  106  are juxtaposed in the patch panel frame  102  to the left of the reinforcement bar  102   b . The ports of the second plurality of multi-port modules  106  are directed at a second angle, relative to a normal line extending away from the front face  102   a , toward the left rail  112   b  of the rack  112 . The ports may be directed at the first or second angle by angling the modules  104  or  106 , or by having the ports formed at an angle within the module  104  or  106 . Furthermore, as mention previously, the multi-port modules  104  and  106  could be horizontal multi-port modules, wherein the ports are angled at the first or second angle. 
     In one embodiment of the present invention, the first angle ranges from approximately ten degrees to approximately forty-five degrees. The second angle also ranges from approximately ten degrees to approximately forty-five degrees. The first and second angles are preferably the same. However, the first and second angles can be different based on the individual applications of the present invention. In the embodiment shown in  FIG. 2 , the first angle and the second angle are approximately twenty degrees and are symmetrical to a normal line, which extends away from the front face  102   a  of the patch panel frame  102  at ninety degrees. 
     The first plurality of multi-port modules  104  are positioned on the right side of the patch panel frame  102  adjacent to the first cable manager  108 . The second plurality of multi-port modules  106  are positioned on the left side of the patch panel frame  102  adjacent to the second cable manager  110 . The first plurality of multi-port modules  104  and the second plurality of multi-port modules  106  are illustrated as being juxtaposed in the patch panel frame, but may be slightly spaced apart in their adjacent state. Furthermore, each of the multi-port modules has a ridge  104   a  or  106   a . A plane defined by the ridges  104   a  and a plane defined by the ridges  106   a  are parallel to the front face  102   a  of the patch panel frame  102 . 
     By mounting the multi-port modules  104  and  106  at the first and second angles, one can conduct or direct the cables  114  toward the cable managers  108  and  110 , respectively. Therefore, the angled modules  104  and  106  exert less stress on the jacks and the portions of the cables  114  near the jacks, as compared to cables  114  connected to the modules at ninety degrees relative to the frame  102 . Furthermore, the angled arrangement makes the technician&#39;s job easier to manage the cables, because the existing cables do not block the labels  200  on the modules, the technician can easily identify a specific cable and plug or unplug a cable into the identified port, without removing other cables. 
     In one embodiment of the present invention, the first and second plurality of multi-port modules  104  and  106  are standard “1100 series” modules, which have six ports. However, the present invention can be used in conjunction with other known or custom designed multi-port modules. Furthermore, the first and second modules do not have to be the same type of modules. It is within the scope of the invention to employ different types of modules for the first and second modules based upon the user&#39;s needs. 
     In the embodiment shown in  FIG. 2 , the patch panel frame  102  can accommodate twenty-eight of the “1100 series” type modules, each of which has six ports; i.e., there is a one hundred and sixty eight port capacity for cable connection in a 5 U sized patch panel frame. This would provide a 33.6 ports per U density. Such a 33.6 ports per U density is a higher density, as compared to conventional designs. Further, this higher density layout is accomplished in an environment, which provides improved strain relief on the connectors, better visibility of labeling, and a neater appearance. 
       FIG. 3  is a perspective view of the frame of the high-density patch panel of  FIG. 2 . As shown in  FIG. 3 , the patch panel frame  102  comprises slots  103  configured at the first angle, and slots  105  configured at the second angle to accommodate the first and the second plurality of multi-port modules  104  and  106 , respectively. The slots  103  are configured to allow only one-way insertion of the multi-port modules  104  and  106 . The slots  103  and  105  lock the first and the second plurality of multi-port modules  104  and  106 , after the first and the second plurality of multi-port modules  104  and  106  are engaged in the slots  103  and  105 . 
       FIG. 4  is a back view of the high-density multi-port-module patch panel of FIG.  2 . The backs of the multi-port modules  104  and  106  include connectors for connection to wires, which are in turn connected to various system devices (not shown), such as devices associated with a network system, a telephone exchange system, etc. The connection of wires to the backs of the modules may be accomplished by wire wrapping of terminals, or insulation displacement connectors (IDCs) or any other type of connectors. 
     The present invention also can be applied to different cable patch panel systems such as electrical cables, telephone cables, and/or network cables of the electrical or fiber optic types. For example,  FIG. 5  is a perspective view of the high-density patch panel frame  202  employing fiber optics modules  204  and  206 , in accordance with another embodiment of the present invention. 
     Accordingly, the high-density patch panel system of the present invention provides a higher port density than conventional patch panel systems because additional space for the horizontal cable manager is not required in the present invention. The present invention also effectively reduces the stress imposed on the cables and connectors adjacent to jacks, and facilitates the technician&#39;s management and maintenance. 
     The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
