Pluggable Optical Board Interconnection System With Flexible Polymeric Waveguides

Pluggable optical board interconnection system using flexible optical waveguide for direct-coupling to reduce the transmission loss is proposed and demonstrated. For the direct coupling between waveguides of boards, we use optical plug and adaptor with flexible polymeric waveguide and guide pins. Flexible polymeric optical waveguide is fabricated using hot embossing technique. Eye pattern and jitter characteristics of the backplane system is presented at 10 Gb/s.
