OISLComm | 고속 광 위성 간 레이저 통신 및 우주 포토닉스 시스템

OISLComm은 1550nm 코히어런트 광 트랜시버와 서브 마이크로 라디안 지향 정밀도를 활용하여 100Gbps~1Tbps 궤도 간 크로스링크를 실현하는 광 위성 간 링크(OISL)를 표준화합니다.

OISLComm 100 Gbps Coherent Intersatellite Optical Crosslink

Sub-micro-radian acquisition, tracking, and pointing (ATP) pipeline between orbital planes

Central System: 1550nm DFB Seed Laser - Radiation-hardened EDFA booster (+33 dBm)

Network Nodes

1550nm DFB Seed Laser
Fast Steering Mirror (FSM)
Coherent Optical DSP
Orbital Ephemeris Pointing

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)
