A parallel-optical interconnect with 12 channels operating at 8.5 Gb/s giving an aggregate data rate of 102 Gb/s is demonstrated, to the authors' knowledge, for the first time. The paper describes and demonstrates 13 × 16-mm cross-section 12-channel parallel-optic transmitter and receiver modules with each channel operating at a data rate of 8.5-10 Gb/s. This was achieved using bottom-emitting 990-nm vertical-cavity surface-emitting lasers and bottom-illuminated InGaAs-InP photodetectors flip-chip bonded directly to 12-channel transmitter and receiver integrated circuits, respectively. In addition, 102-Gb/s link results are demonstrated over 100 m of 50-µm-core standard multimode ribbon fiber. A bit-error ratio of < 10^-13 was measured on a single channel after transmission through 100 m of multimode fiber at a data rate of 8.5 Gb/s with all 12 channels operating simultaneously.
