With urgent demand of the high-resolution observation technology development and the high data rate transmission of information, the research of high-rate laser communication networking technology is imminent. Basic requirement and technical difficulties on the space laser communication networking in realization are analyzed. The new networking optical principle is proposed. A technological solution is studied, which can be used for laser communication through multiple targets at the same time, and an optical antenna of multi-mirror combination is designed based on the paraboloid of revolution, relay optical system, receiving and transmission system and acquisition, pointing, tracking (APT) system. It provides a new technical way for space laser communication network.
