    Abstract: The present invention provides an electromagnetic shielding material and a method for packaging an optical module, where the electromagnetic shielding material includes an electromagnetic shield layer. The electromagnetic shield layer includes an external flux guide layer, an insulation medium layer, and an internal flux guide layer. The external flux guide layer is of a mesh structure, and each mesh forms a first guiding unit. The first guiding unit is of a tapered structure, and the guiding unit forms a first included angle with a horizontal direction. The first included angle is greater than 0 degrees and less than 90 degrees. A cross section of the electromagnetic shield layer is in a sawtooth shape. By means of technical solutions in the present invention, a ground point does not need to be disposed around an optical sub-assembly, adhesive packaging is implemented, and disassembly and assembly, and return for repair are convenient. The electromagnetic shielding material provided in the present invention is a soft material, and only a positioning frame needs to be reserved around the optical sub-assembly. Therefore, mounting efficiency is high, and labor costs are low.

    Abstract: Latch mechanism for communication modules. In an example embodiment, a module latch mechanism includes a follower configured to be slidingly positioned relative to a housing and a driver configured to be rotatingly positioned relative to the housing. The follower includes a first arm configured to facilitate selective engagement of the housing with a host device. The follower may further include a fastening mechanism configured to facilitate selective engagement of the follower with the housing. The driver is configured to be positioned relative to the follower such that the driver urges the follower toward a first position relative to the housing as the driver is rotated from an unlatched position to a latched position.
