A communication system includes a housing, a tray, and a guide arm. The tray has a plurality of ports each having a rear face connectable to a rear cable. The tray is movably engaged with the housing and has a first position substantially inside the housing and a second position substantially outside the housing. The guide arm has a first end pivotably attached to the tray between the plurality of ports and a rear of the housing, and a second free end opposite the first end. The guide arm is adapted to rotate from a first rotational position in which the guide arm is substantially parallel to the rear of the housing to a second rotational position in which the free end points toward the rear of the housing as the tray transitions from the first position to the second position.
