Patch panel with interchangeable front plate

A patch panel, comprising:

• a box-shaped structure comprising a lower wall, an upper wall, and two side walls, a sliding tray along said lower wall of said box-shaped structure, and a front panel configured to be secured to said sliding tray,
• wherein said front panel has a L-shaped profile defined by a first and a second wall that are orthogonal to each other and join together along a common longer edge,
• wherein on each of said first and said second orthogonal walls of said front panel there are holes or openings adapted to receive fasteners so as to secure said front panel to said tray and to the side walls of the box-shaped structure,
• wherein, on each of the first and said second orthogonal walls of said front panel, there are second holes or openings housing sockets and/or adapters, and
• wherein said front panel is configured to be secured to said sliding tray so that a first one of the orthogonal walls of said front panel is adherent to said sliding tray and a second one of the orthogonal walls of said front panel is orthogonal to the sliding tray and closes a front opening of the box-shaped structure when said sliding tray is completely inserted in the box-shaped structure.
