The opticalinterconnection component consists of the signal transmission system, Dove prim and driving mechanism. The planetarygears are used to achieve the speed ratio of 2:1 between the total optical interconnection component and the Dove prism.The C-lenses are employed to couple different optical signals in the signal transmission system. The coupling loss betweenthe receiving fiber of stationary part and the transmitting fiber of rotary part is measured. Hits: 3720 Download times: 188 View Full Text    Download reader
