Multifibre electro-optical modules compatible with the fibre in board technology

Summary form only given. The electro-optical board technology developed in the framework of the Race 2048 HIBITS program provides a full solution for chip-to-chip and board-to-board optical interconnections. In these electro-optical boards, precision alignment parts are embedded to bend the multi mode fibres towards the board surface. These surface optical taps provide alignment and interconnection facilities for electrooptical packages, a ribbon cable or a flexible optical back panel. In this paper we will discuss the different design approaches and realisations for a fibre in board compatible electro-optical package.
