Abstract: An HF-shielded module chassis for the reception of electronic and/or optical modules consisting of two side walls, front and rear module bars that are arranged between the side walls and an upper cover and a lower cover. The upper and lower covers include a honeycomb screen and a surrounding frame of metal that is electrically conductive connected with the honeycomb screen. The front and rear module bars each form the front and rear frame strips of the frame. The two lateral frame strips of the frame have means for the mounting on the side walls.
