FSOCommunications Multi-Beam Spatial Diversity Architecture

Quad-laser optical transmitter mitigating scintillation fades across 5km metropolitan links

Central System: Quad-Beam Laser Array - 4x independent 1550nm optical emitters

Network Nodes

• Quad-Beam Laser Array
• Spatial Diversity Receiver
• Active Building Sway Tracker
• Campus DWDM Aggregator

Architectural Protocol Layers

• Spaceborne PHY/MAC Layer (3GPP Rel-17 TS 38.300): Doppler compensation, HARQ disabling, and timing advance extension.
• Orbital Mesh Routing (CCSDS / Delay-Tolerant Networking): Dynamic topology routing over intermittent laser crosslinks.
• Regenerative Core Processing (OpenRAN / 3GPP CU-DU Split): Onboard user plane function (UPF) local breakout.

Key Metrics: < 18ms (LEO Orbit-to-Ground Roundtrip) | 100 Gbps (Optical Crosslink Throughput) | ±48 kHz (Doppler Shift Compensation) | 99.999% (Orbital Constellation Availability)
