Abstract: A patch panel supports a plurality of energy transmission connectors, and includes a jack holder, a front panel and a cable tray. The jack holder has a plurality of openings in which the connectors can be mounted and has a vertical member and a horizontal member extending at a angle to the vertical member. The vertical member has upper and lower engagement members extending from a surface of the vertical member remote from the horizontal member. The front panel has a vertical section with openings and with upper and lower, rearwardly extending engagement flanges defining a channel between them. The jack holder is mounted in the channel with the engagement members engaging the engagement flanges. The openings of the front panel are aligned with the openings in the jack holder. The cable tray is coupled to and extends forwardly from the vertical section of the front panel.
