High density telecommunications chassis with cable management

A telecommunications chassis is configured for receiving telecommunications equipment. The chassis defines a top, a bottom, a front side, a rear side, a right side, and a left side. The chassis defines a central longitudinal axis extending between the top and the bottom. A first pair of panels is located at the front side, a second pair of panels is located at the rear side, a third pair of panels is located at the right side, and a fourth pair of panels is located at the left side. Each panel defines a plurality of receptacles for receiving the telecommunications equipment. When mounted to a fixed surface, the chassis is rotatable relative to the fixed surface about the central longitudinal axis. Each panel is pivotable away from the other panel of the any given pair of panels about a pivot axis parallel to the central longitudinal axis.
