Optical Inter-satellite Links (OISL) are communication systems that use laser beams to transfer data between satellites in space. These links offer high-speed, high-capacity communication without the need for ground-based relays, allowing satellites to share information directly with each other over long distances. By using optical, rather than radio frequency (RF) communication, OISLs can transmit data at much higher rates with less signal interference,  as well as a low probability of detection. This makes them ideal for satellite constellations in low-Earth orbit (LEO) and beyond, such as for Earth observation, weather monitoring, and global internet services.

OISL are providing expansive communication abilities which enable faster, more efficient data exchange in space, reducing latency, and improving global connectivity as satellite networks continue to expand. MPBC offers space-qualified and customizable optical amplifiers tailored to your mission requirements. Our TRL-9 technology is enabling optical communication for satellite constellations around the globe.
