Product details
Foxcom Iridium Optical Link by is a high-performance fiber optic solution designed to extend Iridium satellite connectivity deep into enclosed, underground, or isolated environments. By eliminating the need for a direct line of sight to the sky, it ensures uninterrupted, mission-critical communications inside military bunkers, submarines, maritime vessels, underground facilities, and offshore oil rigs when primary networks fail. Iridium Optical Link bridges the gap between isolated indoor environments and external satellite constellations. In complex structures where traditional, bulky coaxial cables suffer from severe signal attenuation, optical fiber delivers near-zero transmission loss, superior signal quality, and complete electrical isolation against lightning risks. Optical fiber helps reduce RF transmission loss, improve signal quality, provide lightning protection, and support safer, easier installation. The core system kit features Foxcom ruggedized Sat-Light G4000 Series outdoor unit (ODU), a compact indoor unit (IDU), dual high-gain outdoor Iridium antennas, and all necessary RF coaxial jump cables. For facilities requiring comprehensive situational awareness, the system is fully expandable; Foxcom can integrate or co-deploy separate GPS and Inmarsat systems alongside the Iridium link to create a unified, multi-constellation satellite coverage footprint.
