Rugged Ethernet & Optical Connectivity for Satellite Systems
Satellite communications—whether for earth observation, broadband backhaul, or telemetry—demand highly reliable and compact data interfaces. LINK‑PP provides shielded magnetic RJ45 connectors, industrial-grade LAN transformers, and optical interface support suitable for satellite terminals, payload modules, and ground stations. Our solutions ensure signal integrity, space efficiency, and environmental durability in aerospace-grade environments.
Connectivity Requirements in Satellite Equipment
- High Data Integrity — Long-distance uplinks require minimized signal loss and excellent EMI immunity
- Compact Form Factors — Space-grade and onboard equipment have stringent volume limitations
- Radiation & Thermal Stability — Components must tolerate extreme temperature and radiation exposure (for spaceborne)
- Multi-interface Compatibility — Ethernet + optical hybrid connectivity is often deployed in telemetry ground stations
