Optical module
The present disclosure provides an optical module, including a circuit board, an optical chip and an optical chip driver. Where the circuit board includes a first layer provided with a first ground plane, a second layer provided with a second ground plane and a high-speed signal line between the first ground plane and the second ground plane. At least a part of the high-speed signal line is enclosed in a shielding cage which is formed by the first ground plane, the second ground plane and a plurality of metal vias connecting the first ground plane and the second ground plane in a way that the at least a part of the high-speed signal line is electromagnetic shielded by the shielding cage.
