Optical Module Cover Plate Processing Technology
CPO enhances interconnect bandwidth and energy efficiency by integrating optics and electronics within a single package, significantly shortening electrical link lengths. This innovation is crucial as data center traffic surges, driven especially by AI and high-performance computing. UTG (Ultra-Thin Flexible Glass) covers are currently the mainstream choice for foldable devices, and their production processes are mainly divided into two types: one-step forming and two-step forming (thinning) methods. The one-step forming method refers to directly producing an ultra-thin sheet. In order to reduce the load mass and solve the problem that the aluminum alloy optical cover plate of exoplanet imaging coronagraph was easy to deform, based on the equal generation design method, this paper designed and determined the configuration of the carbon fiber optical cover plate.
