Overview
Surgical lighting systems are becoming imaging hubs. As they integrate high-performance cameras, they support surgical recording, medical education, remote consultation, robotic-assisted procedures, AI-based image analysis, and real-time collaboration — and that raises what the video link underneath has to do.
Conventional transmission is reaching its practical limits. Electrical cable is exposed to electromagnetic interference, mechanical fatigue from continuous arm movement, bulky routing, weight, and distance constraints. Wireless simplifies installation but generally depends on compression and a shared RF environment, which introduces latency, image degradation, and reliability concerns.
The paper sets out how uncompressed optical transmission answers those constraints, and how OptoHub's 4K Camera Optical Interface Board lets OEMs build on it — covering the transmitter and receiver board architecture, power and size figures, and a worked connection example.
