We have demonstrated 2.5-Gb/s single-mode fiber-optic transmission using room temperature vertical-cavity surface-emitting lasers (VCSELs) operating at 1.54 μm. The experiments were done over 60-km conventional single-mode fiber and over 75-km dispersion shifted fiber without optical amplification. Transmission over 200 km with one optical amplifier was also observed. Single-mode operation was demonstrated with a side-mode suppression-ratio of 50 dB under pseudo-random modulation. The maximum bandwidth was limited by parasitics to 4.7 GHz.
