Abstract
An optical connector includes a printed circuit board, a substrate, a photoelectric die, a number of wires, a lens element, and an optical fiber. The substrate is mounted on the printed circuit board. The photoelectric die is wire-bonded to the substrate by the wires. The photoelectric die is packaged by the lens element, the substrate and the printed circuit board and optically coupled to the optical fiber by the lens element.
Claims6
An optical connector, comprising:
- a printed circuit board;
- a substrate mounted on the printed circuit board and comprising:
- a firs layer positioned on the printed circuit board;
- a second layer positioned on the first layer and defining a first through hole, the second layer comprising a plurality of bonding pads on a side opposite to the first layer;
- a third layer positioned on the second layer and defining a second through hole, the second through hole being concentric with and larger than the first through hole, the second layer comprising a plurality of bonding pads on a side opposite to the first layer and received in the second through hole;
- a fourth layer positioned on the third layer and defining a third through hole being concentric with and lager than the first through hole;
- and
- a plurality of vias connecting the bonding pads to the printed circuit board;
- a photoelectric die positioned on the first layer and received in the first through hole;
- a plurality of wire bonding to the photoelectric die and the bonding pads;
- an optical fiber;
