An optical signal transmission apparatus () for a rotating antenna comprising a plurality of optical modulators () arranged for receiving a respective plurality of analog RF signals () and for modulating a respective plurality of optical signals therewith to produce a plurality of modulated analog optical signals (). A plurality of opto-electrical converters () each converts a respective modulated analog optical signal () into an analog electrical signal. The plurality of optical modulators () are rotationally coupled in optical communication with the plurality of opto-electrical converters () via an optical rotary joint () including a reversion prism.
