In the race of commercial spaceflight, an invisible key player is emerging—the companies providing communication arteries for satellites.

A leading domestic enterprise is considered an invisible champion in this field. As one of only two companies worldwide and the only domestic manufacturer capable of mass-producing 100Gbps inter-satellite laser communication modules, it holds over 50% market share in China, with technology levels firmly standing in the international top tier.

How hardcore are their products? Transmission distances exceed 1000 kilometers, with low power consumption and miniaturized designs perfectly adapted to extreme space environments. 400G has been successfully validated in orbit, and 1.6T is still in development. Behind the scenes, they are deeply integrated with national satellite internet projects (over 4 billion yuan in orders), and are also a core supplier for SpaceX Starlink. In 2024, this business segment alone generated 800 million yuan in revenue.

Financial data is even more noteworthy: confirmed revenue of 120 million yuan in the first half of 2025, an estimated 650 million yuan for the full year, and a potential breakthrough to over 1.5 billion yuan by 2026. By vertically integrating the entire industry chain from optical chips to modules, the chip self-sufficiency rate exceeds 70%, with a gross profit margin of 48%, becoming a new engine for performance growth.

This is a microcosm of domestic substitution in satellite internet—accelerating the formation of an independent and controllable industrial closed loop from underlying chips to system integration.
