The present invention provides an electromagnetic shielding material and a method for packaging an optical module. The electromagnetic shielding material comprises an electromagnetic shielding layer, and the electromagnetic shielding layer comprises an external flux guide layer, an insulation dielectric layer and an internal flux guide layer. The external flux guide layer has a net-shaped structure, each mesh forms a first guide unit, the first guide unit has a tapered structure, the guide unit forms a first angle with the horizontal direction, and the first angle is greater than 0° and smaller than 90°. The electromagnetic shielding layer has a zigzag cross section. By means of the technical solution of the present invention, there is no need to set a ground point around an optical sub-assembly, adhesive packaging is implemented, and the assembly/disassembly and repair are convenient. The electromagnetic shielding material provided by the present invention is a soft material, only a positioning frame needs to be reserved around the optical sub-assembly, the mounting efficiency is high and the labor cost is low. |
