OISLNet | Global Intersatellite Optical Network & Space Transport Backbone
OISLNet provides carrier-grade optical transport in orbit—encapsulating high-capacity client traffic via Optical Transport Network (OTN/ITU-T G.709) frames across high-altitude laser meshes.
OISLNet Space OTN Digital Transport Architecture
Hierarchical framing (OTU4 / ODUflex) over spaceborne DWDM reconfigurable optical add-drop multiplexers
Central System: Client Ingress Gateway - Ethernet, eCPRI and Fibre Channel mapping
Network Nodes
- Client Ingress Gateway
- Spaceborne Micro-ROADM
- Space OTN Framer (ITU-T G.709)
- Multi-Plane OISL Grid
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)
