Abstract
Optical signals are transmitted across a rotary junction using an active optical rotary coupler. A rotary optical joint assembly includes a rotatable optical coupler and an optical signal processing system. The rotatable optical coupler aligns two optical fibers for optical communication across a rotary optical junction. The optical signal processing system includes a local optical transceiver that receives the signals and compensates for at least a portion of signal loss or other signal imperfections incurred from transmitting the signal across the rotary optical junction. The local optical transceiver also processes the signals for longer distance transmission.
