Abstract
Optical and RF energy may be provided simultaneously or otherwise across a rotary coupler using separate communication paths. The rotary coupler may be provided with an optical transmission line that passes inside or through the center of an inner conductor of a coaxial RF transmission line that itself extends across the rotational interface/s of the rotary coupler. Both the optical transmission line and the RF transmission line may be positioned at, or close to, the axis of rotation of the rotary coupler. The rotary coupler may be configured to transfer optical and RF energy across rotational interface/s of the rotary coupler using an optical rotary joint positioned inside the inner conductor of a RF channel transmission line that itself is substantially centered at, and in line with, the rotational axis of the rotary coupler.
