A 120Gb/s parallel optical transmitter using 850nm VCSELs for 12-fiber ribbon (12 channels x 10Gb/s/ch) is described and experimentally verified. All channels run simultaneously, driven a custom-built low cost 120Gb/s test station. Open eyes are obtained at 300m and error free operation with margin is confirmed. A 2.3dB penalty is observed for simultaneous transmission compared to single channel operation. The transmitter consumes 1.3W and occupies the same volume as existing 40Gbps modules.
