Paper Abstract

In this paper, we report the low loss (<0.06dB single-mode, <0.2dB multi-mode) 90°-bent with 1mm-bending radius optical fiber by using 12-fiber ribbon for optical interconnection systems in both the single-mode and multi-mode case. There are a lot of 90° light deflection techniques based on several types of 45° mirrors.[1]-[6] Our 90° light deflection technique is based on bending optical fiber itself.[7] This technology is easy to be adopted for optical surface mount assemblies that need light beam deflection between the vertical surface-emitting lasers or surface-receiving photodiodes and optical paths parallel to an electric circuit board. We describe the target of our developing system, concepts, difficulty of glass fiber bending by failure probability, a single-mode fiber design for small bending with low bending losses, multi-mode 90°-bent structure using polymer materials and the 80μm-cladding 125μm spacing 12-fiber ribbon for dense packaging and easy handling in narrow spaces. We also describe the 90°-bent connector which has guide-pins splice able with conventional 12MT-connector, a 5Gbit/s×12ch parallel-optical module and these characteristics. Our developing optical interconnection system include the 90°-bent with R=1mm connector and parallel module have good performances for the practical use.
