Record-high 25.25-Gb/s real-time end-to-end optical orthogonal frequency-division multiplexing transmissions over an intensity-modulation and direct-detection-based 300-m OM2 multi-mode fiber links are achieved with a tri-sub-band transceiver architecture. A 9.75-Gb/s baseband signal is RF multiplexed with two 7.75-Gb/s sub-bands, which are IQ modulated onto a 6.125-GHz RF carrier. The adaptive bit/power-loaded, independently power-optimized sub-bands sampled at 4 GS/s are multiplexed to intensity modulate an EML. Similar BERs and <0.5-dB optical penalties are observed for all sub-bands.
