A connector assembly includes a motherboard and a connector. The motherboard defines a first plane and includes at least one fiber trace. The connector includes an optical lens, an electrical/optical converter, an electrical connector, and a circuit board connecting the optical lens and the electrical connector. The optical lens can be arranged to receive and transmit light from the at least one fiber trace in a direction that is parallel or substantially parallel to the first plane. A plane defined by at least a portion of a main surface of the circuit board is perpendicular or substantially perpendicular to the first plane. The at least one fiber trace is arranged to transmit light to and away from an edge of the motherboard and is arranged to receive light at the edge of the motherboard.
