摘要
Optical interconnection between LSIC （Large Scale Integrated circuit） is an increasing demand as data communication is growing very fast, whereas electronic interconnection could hardly satisfy the fastgrowing request of data rate. 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.
