X-Band Optical Uplink | GL952XU
The GL952XU from Global Foxcom’s Sat-Light™ Gold Series is a high-performance optical uplink for X-Band operation. Spanning 7.25 to 8.4 GHz, it enables transparent RF over fiber between ground antennas and control facilities, supporting long inter-facility spans of around 15 km.
Features & Benefits
- Reliable transmission over distances up to 15 km
- Adjustable gain control on both transmitter and receiver
- Low group delay, phase distortion, and slope variation
- Front-panel test port and diagnostic status LEDs
- Compact form factor for rack-mounted deployments
- Compatible with first-generation Sat-Light™ systems
Built for high-frequency uplink applications, the GL952XU ensures low-loss, high-fidelity signal transport across long distances using fiber optics. Supporting the full 7.25 to 8.4 GHz X-Band range, it minimizes slope, group delay, and phase distortion while preserving carrier integrity. With adjustable gain control, front-panel diagnostics, and a compact design, it offers the control and consistency required for uplink chains in satellite ground stations and remote antenna environments.
