A telecommunications device including a chassis having a housing in which a plurality of splitter devices are contained. The housing includes top and bottom walls, front and back ends, and opposing sides. A circuit board is positioned at the back end of the housing. The circuit board includes a front face that faces toward the front end of the housing. The circuit board also includes an upper portion that extends higher than the top wall of the housing and a lower portion that extends lower than the bottom wall of the housing. First telecommunications connectors are mechanically coupled to the front face of the circuit board at the upper portion, and second telecommunications connectors are mechanically coupled to the front face of the circuit board at the lower portion. The chassis of the telecommunications device defines upper open side regions for allowing cables to be routed laterally from adjacent the sides of the chassis to the first telecommunications connectors. The upper open side regions are located above the top wall of the card housing and adjacent to the back end of the card housing.
