When the Dove prism is rotated an angle of at around the longitudinal axis, the image rotates an angle of 2 at. The optical interconnection component consists of the signal transmission system, Dove prim and driving mechanism. The planetary gears are used to achieve the speed ratio of 2：l between the total optical interconnection component and the Dove prism. The Clenses are employed to couple different optical signals in the signal transmission system. The coupling loss between the receiving fiber of stationary part and the transmitting fiber of rotary part is measured.展开更多

A realization of on-board optical connection is described in this paper,of which multimode fibers were buried into the RF4 board by cutting grooves on the surface of the board with a LPKF ProtoMat95sll, and two MT connectors were reconstructed to form an input-and-output couple in the board. Optical transmission at 2.5 Gbit/s× 12 channels data rate was demonstrated and a widely opening eye pattern was achieved. Large scale prototype of dense-multimode-fiber-embeddad board for the backplane aoolication was also fabricated by using the methods mentioned in this oaeer.展开更多
