3.3-Tb/s compact optical fiber package using pre-formed optical fiber

We developed a compact optical fiber package for rack-to-rack transmission in information communication technology. Using pre-formed optical fiber instead of optical fiber strands and ribbon fiber, we achieved a reduction in the routing area and protection of the optical fiber. We fabricated a prototype mock-up board with optical modules and achieved a bandwidth of 3.3 Tb/s and an area of 4500 mm

. We confirmed a good transmission performance board-to-board with 5 m of optical cable at 25 Gb/s (PRBS: 2
